Background Distal tibia osteomyelitis (DTO) treatment has become a challenging problem due to its difficult treatment and special location. Our goal is to provide a comprehensive and individualized treatment strategy, and to investigate the associated complications.Methods We retrospectively analyzed the data of 70 patients with DTO diagnosed and treated in our hospital from January 2015 to January 2022. The average age was 42.5 years (12–73 years), there were 34 cases accompanied by bone defects, and the average length of the bone defect was 3.2 cm (2 cm–17 cm). We divided the patients into three groups based on infection severity and specific location: 25 cases of a simple type (S type), 23 cases of complex ankle non-involved type (CAN type), and 22 cases of complex ankle involved type (CAI type). Comprehensive individualized treatment, including debridement, reconstruction, arthrodesis, and other surgical methods, was performed on patients of various types, rehabilitation exercises were guided, and patients were closely monitored. The efficacy was assessed using the following criteria: (1) treatment and related complications; (2) infection and defect healing; (3) improvement of ADL, VAS, and AOFAS scores; (4) evaluation of patients undergoing Ilizarov distraction osteogenesis; and (5) evaluation of patients undergoing ankle arthrodesis.Results The follow-up time was 30 months (10–84 months). With the exception of three patients who required amputation due to aggravated infection and concomitant basic diseases, all patients achieved infection control and healing, and the complications were properly treated. Three scores of patients with different types were significantly improved, and the differences were statistically significant. Patients undergoing Ilizarov distraction osteogenesis had satisfactory results, and the superior rates of ASAMI bone evaluation and function evaluation were 89%. All patients with ankle arthrodesis finally achieved bone healing, and the average fusion time was 4.5 months (3–7 months).Conclusion The comprehensive individualized treatment strategy is reliable for the treatment of DTO, as it can guide individualized treatment under different conditions, solve the problem of bone and soft tissue defects while controlling infection, reduce complications and properly handle them, and save as much function of the affected limb as possible.

Diet is an important factor that can exacerbate or ameliorate chronic inflammation, which has been implicated in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). However, no prospective study has yet investigated the relation between the inflammatory potential of diet and NAFLD. The aim of this study was to investigate the association between the inflammatory potential of the diet and the risk of NAFLD.The study included 12,877 participants aged over 18 years (mean [standard deviation]: 39.4 [11.5] years). Dietary intake was assessed at baseline through food frequency questionnaires. Using white blood cell count as the inflammatory marker, we newly created a dietary inflammatory potential score by reduced rank regression and stepwise linear regression. NAFLD was identified by abdominal ultrasound during yearly health checkups. Cox proportional hazards regression models were used to estimate the association between the dietary inflammatory potential score and the risk of NAFLD.During a median follow-up period of 4.2 years, 2744 first incident cases of NAFLD occurred. After adjustment for potential confounders, the multivariable hazards ratios (95% confidence intervals) for NAFLD across increasing quartiles of the dietary inflammatory potential score were 1.00 (reference), 1.01 (0.90, 1.13), 1.15 (1.03, 1.29), and 1.26 (1.13, 1.41), with P for trend0.0001. This positive association appeared greater in men than in women (P for interaction = 0.02).Our results indicate that a dietary pattern with high inflammatory potential is associated with a higher risk of NAFLD. Such findings provide the support that inflammation may be a potential mechanism linking diet to the risk of NAFLD.

Ultra-processed foods make up more than 50% of daily energy consumed in Western countries and are rapidly increasing in China. However, little is known about the association between ultra-processed food intake and muscle strength, a predictor for physical disability in senior years. We aimed to investigate the association of ultra-processed food intake with longitudinal changes in grip strength among middle-aged and older Chinese adults. This prospective cohort study included a total of 5409 adults aged 40 years and over (61.3% men). Ultra-processed food intake was obtained by means of a validated food frequency questionnaire and classified according to the NOVA classification system. Grip strength was measured annually using a handheld digital dynamometer. Multivariable linear regression models were used to examine the association between ultra-processed food intake and annualized change in grip strength and weight-adjusted grip strength. In the fully adjusted models, annualized changes in grip strength and weight-adjusted grip strength per 10% increment in the proportion of ultra-processed foods in the diet were − 0.3708 kg (95% confidence interval − 0.5687, − 0.1730; P 0.05). Our data indicate that higher ultra-processed food intake was associated with faster grip strength decline in middle-aged and older Chinese adults.

Background: Soy foods contain high levels of soy protein or isoflavones, which can stimulate muscle protein synthesis and increase antioxidant capacity, and thus ameliorate muscle strength decline. However, data from epidemiological studies investigating the association of habitual soy food consumption with muscle strength decline among general Chinese adults are limited. Methods: This study included 29,525 participants (mean age: 41.6 years; 16,933 (53.8%) males). Soy food consumption was evaluated using a validated 100-item food frequency questionnaire. Handgrip strength (HGS) was assessed with a hand dynamometer. Analysis of covariance were performed to assess the multivariable-adjusted least square means (LSM) and 95% confidence interval (CI) for HGS. Results: The multiple adjusted LSM (95% CI) of HGS across soy food consumption were 35.5 (34.2, 37.1) kg for

Background Both absolute (kg) and relative (kg per kg of body weight) handgrip strength (HGS) have been used as indicators of HGS. Multiple studies have explored HGS associations with type 2 diabetes (T2DM); however, prognostic values were inconsistent. We aimed to examine the associations between both absolute and relative HGS and incident T2DM. Methods A total of 12,957 participants aged 40 years and older (mean age 51.0 years, 58.4% men) were followed and enrolled in the Tianjin Chronic Low-grade Systemic Inflammation and Health (TCLSIH) Cohort Study. Cox proportional hazards regression models were used to examine the association of HGS with incident T2DM. Other prospective studies on HGS and risk of T2DM were identified by searching several electronic databases up to November 31, 2021. Meta-analysis was performed by combining the results from the TCLSIH study and previous prospective cohort studies. Results From the TCLSIH Cohort study, after adjustment, relative HGS was inversely associated with T2DM (hazard ratio per 0.1 higher relative HGS 0.667, 95% confidence interval [CI] 0.616, 0.722). However, no significant association between absolute HGS and incident T2DM was found. The meta-analyses showed that per 5 kg higher HGS was associated with a 5% (95% CI 2%, 8%) lower risk of T2DM and each 0.1 higher relative HGS was associated with a 22% (95% CI 14%, 29%) lower risk of T2DM. Conclusion The results from our cohort study and meta-analysis suggest that relative HGS was better than absolute HGS in predicting incident T2DM. Adiposity was an important factor that mediates the association between HGS and T2DM.

Two large prospective cohorts from China and the UK have firstly demonstrated that habitual onion consumption was associated with a lower risk of depressive symptoms in the general population.

Summary Background and aims Prospective cohort studies linking dietary patterns and non-alcoholic fatty liver disease (NAFLD) are limited, especially in Asian populations. This study aimed to prospectively investigate the association between dietary patterns and risk of NAFLD in a general Chinese adult population. Methods This study included a total of 17,360 participants free from NAFLD at baseline. Dietary patterns at baseline were identified with factor analysis based on responses to a validated 100-item food frequency questionnaire. NAFLD was diagnosed by abdominal ultrasound after excluding other causes related to chronic liver disease. Cox proportional regression models were used to assess the association between dietary patterns and risk of NAFLD. Results During a median follow-up of 4.2 years, 4034 NAFLD cases were documented. Three main dietary patterns were extracted: sugar rich dietary pattern, vegetable rich dietary pattern, and animal food dietary pattern. After adjusting for age, sex, body mass index, smoking, alcohol, education, occupation, income, physical activity, total energy intake, personal and family history of disease, depressive symptoms, dietary supplement use, inflammation markers, and each other dietary pattern score, comparing the highest with the lowest quartiles of dietary pattern scores, the multivariable hazard ratios (95% confidence interval) of NAFLD were 1.11 (1.01, 1.23) for sugar rich dietary pattern, 0.96 (0.86, 1.07) for vegetable rich dietary pattern, and 1.22 (1.10, 1.36) for animal food dietary pattern. Further adjustment for waist circumference instead of body mass index provided similar results. Conclusion Dietary patterns rich in animal foods or sugar were associated with a higher risk of NAFLD among Chinese adults, whereas a vegetable rich dietary pattern was not associated.

BACKGROUND Although preserved egg is a traditional Chinese delicacy widely consumed in China and Southeast Asian countries, whether habitual preserved egg consumption is associated with nonalcoholic fatty liver disease (NAFLD) remains unknown. OBJECTIVES This study aimed to examine the association between preserved egg consumption and risk of NAFLD in a cohort of Chinese adults. METHODS This prospective cohort study included 15,883 participants aged 19-88 y (58% women) from the TCLSIH (Tianjin Chronic Low-grade Systemic Inflammation and Health) cohort study who were free of liver diseases, cancer, and cardiovascular disease at baseline. Preserved egg consumption was assessed using an FFQ at baseline. NAFLD was diagnosed by transabdominal sonography during an annual health examination. Multivariable Cox proportional hazards regression models were used to calculate HRs and 95% CIs across categories of preserved egg consumption. RESULTS During 56,002 person-years of follow-up, 3683 first incident cases of NAFLD were recorded. After adjustment for sociodemographic characteristics, lifestyle risk factors, total energy intake, egg intake, and eating patterns, the multivariable HRs (95% CIs) of incident NAFLD according to categories of preserved egg consumption were 1.00 (reference) for never, 1.05 (0.98, 1.14) for

The independent role of muscular strength in the prevention of chronic disease is increasingly being recognized. However, no cohort study has assessed the relationship between handgrip strength and the incidence of hypertension among the middle-aged and older population. The aim of this prospective cohort study was to investigate whether handgrip strength is related to incident hypertension among people aged 40 years and over.This prospective cohort study (n = 8,480) was performed between 2013 and 2019 as part of the Tianjin Chronic Low-grade Systemic Inflammation and Health (TCLSIH) Cohort Study, Tianjin, China.Participants without baseline hypertension were followed up for ~6 years (median 4.0 years). Hypertension was defined according to the JNC7 criteria. Handgrip strength was measured using a hydraulic handheld dynamometer. Adjusted Cox proportional hazards regression models were used to assess the relationships between weight-adjusted handgrip strength and the risk of incident hypertension.The incidence rate of hypertension per 1000 person-years was 70. The fully adjusted hazards ratios (95% confidence interval) of the incidence of hypertension for increasing quartiles of weight-adjusted handgrip strength were: 1.00(reference), 0.84 (0.75-0.95), 0.78 (0.69-0.88), and 0.66 (0.58-0.75) (P for trend0.0001). Moreover, the adjusted hazards ratio (95% confidence interval) of incident hypertension for per unit increase in weight-adjusted handgrip strength was 0.17 (0.10-0.27) (P0.0001). Similar results were observed in males and females.The present cohort study is the first to find that high weight-adjusted handgrip strength, but not absolute handgrip strength, is significantly and independently related to low risk of incident hypertension among the middle-aged and older population.

It has been suggested that added sugar intake is associated with non-alcoholic fatty liver disease (NAFLD). However, previous studies only focused on sugar-sweetened beverages; the evidence for associations with total added sugars and their sources is scarce. This study aimed to examine the associations of total added sugars, their physical forms (liquid vs. solid), and food sources with risk of NAFLD among adults in Tianjin, China. We used data from 15,538 participants, free of NAFLD, other liver diseases, cardiovascular disease, cancer, or diabetes at baseline (2013-2018 years). Added sugar intake was estimated from a validated 100-item food frequency questionnaire. NAFLD was diagnosed by ultrasonography after exclusion of other causes of liver diseases. Multivariable Cox proportional hazards models were fitted to calculate hazards ratios (HRs) and corresponding 95% confidence intervals (CIs) for NAFLD risk with added sugar intake. During a median follow-up of 4.2 years, 3,476 incident NAFLD cases were documented. After adjusting for age, sex, body mass index and its change from baseline to follow-up, lifestyle factors, personal and family medical history, and overall diet quality, the multivariable HRs (95% CIs) of NAFLD risk were 1.18 (1.06, 1.32) for total added sugars, 1.20 (1.08, 1.33) for liquid added sugars, and 0.96 (0.86, 1.07) for solid added sugars when comparing the highest quartiles of intake with the lowest quartiles of intake. In this prospective cohort of Chinese adults, higher intakes of total added sugars and liquid added sugars, but not solid added sugars, were associated with a higher risk of NAFLD.

Introduction: Mounting evidence has demonstrated that skeletal muscle and visceral adiposity play crucial roles in glucose metabolism. The purpose of this study was to investigate whether the appendicular skeletal muscle mass index (ASMI) to trunk fat mass (TFM) ratio (ASMI/TFM) is a more specific and identifiable factor for type 2 diabetes mellitus (T2DM) in older adults than conventional anthropometric measures. Methods: This cross-sectional study included 1,370 older adults from the Tianjin Chronic Low-Grade Systemic Inflammation and Health (TCLSIH) cohort. ASMI and TFM were measured by using a bioelectrical impedance analyzer, and T2DM was defined with the criteria of the American Diabetes Association. Odds ratios (ORs) were evaluated using multivariable logistic analysis. Results: The prevalence of T2DM is 20.0% in this study. The multivariable-adjusted ORs (95% confidence interval) of T2DM for increasing categories of ASMI/TFM, BMI, and waist circumference (WC) were 1.00 (reference), 0.70 (0.49, 1.02), 0.61 (0.42, 0.89), and 0.45 (0.30, 0.67; p for trend p for trend = 0.10); and 1.00 (reference) and 1.78 (1.19, 2.74; p < 0.01), respectively. Conclusions: Higher ASMI/TFM was associated with a lower prevalence of T2DM in this study of older adults. The T2DM predictive value of ASMI/TFM may be stronger than BMI and WC in this population.

Results of in vitro and in vivo studies showed that green leafy vegetables (GLV) could attenuate liver steatosis. However, little is known regarding the association between GLV intake and nonalcoholic fatty liver disease (NAFLD) in human. We examined the association of GLV intake with NAFLD in a large-scale adult population.This cross-sectional study investigated 26,891 adults in China who participated in health examinations from 2013 to 2017. Newly diagnosed NAFLD was detected by liver ultrasonography. Dietary intake was assessed by using a validated and standardized food frequency questionnaire. Multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) across categories of GLV intake. After adjustment for sociodemographic characteristics, lifestyle factors, and other dietary intakes, the OR (95% CI) for comparing the highest vs. lowest GLV intake categories (≥7 times/week vs. almost never) was 0.72 (0.59, 0.90) (P 0.0001). In addition, a linear inverse association was demonstrated between GLV intake and NAFLD in women (P for trend = 0.04), but ORs for any intake category did not reach significance. Stratified analyses suggested a potential effect modification by obesity status; the ORs (95% CIs) for comparing the highest vs. lowest GLV intake categories was 0.72 (0.54, 0.97) in normal/overweight individuals and 1.04 (0.65, 1.65) in obese individuals (P-interaction 0.0001).This large population-based study shows that high GLV intake is inversely associated with NAFLD, particularly in women and non-obese participants.

Fish contain many important nutrients and are primarily known for high n-3 polyunsaturated fatty acids (n-3 PUFA) content. Studies have shown that supplementation of fish oil-derived n-3 PUFA improves muscle mass and strength. Here, we hypothesized that fish consumption might improve muscle strength. To test this hypothesis, we performed this cross-sectional study (n = 29,084) in Tianjin, China. The frequency of fish consumption was assessed using a valid self-administered food frequency questionnaire. Handgrip strength (HGS) was used as the indicator of muscle strength, and was measured using a handheld digital dynamometer. Analysis of covariance was used to examine the relationship between fish consumption and HGS. In men, after adjusted potential confounding factors, the least square means (95% confidence intervals) of HGS across saltwater fish consumption categories were 41.5 (41.1, 43.7) kg for1 time/week, 44.6 (43.2, 45.8) kg for 1 time/week, and 44.7 (43.3, 46.1) kg for ≥2 to 3 times/week (P for trend0.001). In men, the least square means (95% confidence intervals) of HGS across the ascending quartiles of dietary n-3 PUFA intake were 43.6 (43.2, 44.4) kg, 43.7 (43.2, 44.6) kg, 44.4 (43.0, 45.8) kg, and 44.6 (43.1, 46.0) kg (P for trend0.01). The results showed that saltwater fish consumption was positively related to HGS in men, but not in women, suggesting that saltwater fish contain nutrients that may be used to improve HGS.

BACKGROUND Wholegrains contribute a range of beneficial nutrients, such as dietary fiber and several minerals and vitamins, that are beneficial to depressive symptoms. However, there are a few studies aimed at exploring whether a wholegrain diet is related to depressive symptoms. We conducted this study to investigate the relationship between wholegrains consumption and depressive symptoms. METHODS This cross-sectional study included a total of 24,776 (mean age: 39.9 years, age range: 18.1-91.3 years; males, 54.1%) inhabitants living in Tianjin, China. Wholegrains consumption was assessed using a valid self-administered food frequency questionnaire. Depressive symptoms were evaluated using the Chinese version of Zung Self-Rating Depression Scale (SDS) and the cutoff point was set at 45. Multiple logistic regression analysis was used to estimate the relationship between wholegrains consumption and depressive symptoms. RESULTS The prevalence of depressive symptoms was 19.1% and 22.4% in males and females, respectively. After adjustments for potential confounding factors, the odds ratios (95% confidence intervals) of depressive symptoms across wholegrains consumption were 0.77 (0.65-0.91) for

Thyroid hormones (THs) play an important role in both serum uric acid (SUA) excretion and purine nucleotide metabolism. Past research mainly focused on the relationships between thyroid dysfunction and hyperuricemia. Although most subjects at risk for hyperuricemia are euthyroid, few studies have investigated the predictive values of THs on incident hyperuricemia in euthyroid adults. This study aimed to examine how free triiodothyronine, thyroxine, and thyroid-stimulating hormone are related to incident hyperuricemia in euthyroid subjects.Participants without baseline hyperuricemia were recruited from Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study and followed up for ∼6 years. Thyroid function was determined by chemiluminescence immunoassay methods. Hyperuricemia was defined as SUA ≥416.5 μmol/L for males and ≥357.0 μmol/L for females. Thyroid function and SUA were assessed yearly during follow-up. Adjusted Cox proportional hazards regression models were used to assess the relationship between thyroid function and hyperuricemia.The incidence rates of hyperuricemia were 109 and 50 per 1000 person-years in males and females, respectively. In males, compared with the lowest quartile, the multivariable-adjusted hazards ratios for hyperuricemia in the highest quartiles of triiodothyronine, thyroxine, and thyroid-stimulating hormone were 0.57 (0.50-0.66), 0.63 (0.54-0.73), and 1.03 (0.90-1.19) (P for trend.0001,.0001, and .51), respectively. However, no statistically significant correlations between thyroid function and incident hyperuricemia in females were found.This cohort study is the first to demonstrate that higher THs are related to lower risk of incident hyperuricemia in a male population with euthyroid status.

Seaweeds have numerous biologically active ingredients, such as polysaccharides, polyphenols and carotenoids, that are beneficial to human health. Although these benefits might be related to the synthesis, secretion or reabsorption of uric acid, no studies have explored the relationship between seaweeds consumption and hyperuricaemia (HUA) in the general population. The aim of this study was to investigate whether seaweeds consumption is related to HUA in a large-scale adult population. A cross-sectional study was conducted with 32 365 adults (17 328 men and 15 037 women) in Tianjin, People’s Republic of China. Frequency of seaweeds consumption was assessed by a validated self-administered FFQ. HUA was defined as serum uric acid levels >420 μmol/L in men and >350 μmol/L in women. The association between seaweeds consumption and HUA was assessed by multiple logistic regression analysis. Restricted cubic spline functions were used for non-linearity tests. The prevalence of HUA in men and women was 21·17 % and 5·93 %, respectively. After adjustments for potential confounding factors, the OR (95 % CI) for HUA across seaweed consumption (g/1000 kcal per d) were 1·00 (reference) for level 1, 0·91 (95 % CI 0·81, 1·02) for level 2; 0·90 (95 % CI 0·81, 1·01) for level 3; 0·86 (95 % CI 0·78, 0·97) for level 4 in men and 0·90 (95 % CI 0·73, 1·10) for level 2; 0·82 (95 % CI 0·67, 1·00) for level 3; 0·84 (95 % CI 0·68, 1·03) for level 4 in women, respectively. A negative correlation between seaweeds consumption and HUA in males but not in females was observed. Further studies are needed to explore the causal relationship.

Thyroid hormones, including free triiodothyronine (FT3), free thyroxine (FT4), have well-recognized effects on the cardiovascular system. However, the evidence is lacking regarding the relationship between repeated FT3, FT4, and thyroid-stimulating hormone (TSH) measurements and incident hypertension. The aim of this cohort study was to examine how longitudinal trends of serum FT3, FT4, and TSH levels are related to the development of hypertension in a euthyroid population. A prospective study (n = 5926) was performed in Tianjin, China. Participants without a history of hypertension were followed up for ~4 years (median: 3 years). Hypertension was defined according to the criteria of JNC7. FT3, FT4, and TSH were determined by chemiluminescence immunoassay methods. FT3, FT4, TSH, and blood pressure were assessed yearly during follow-up. Adjusted Cox proportional hazards regression models were used to assess the relationships between baseline, means, and annual changes in FT3, FT4, TSH, and hypertension. The incidence rate of hypertension per 1000 person-years was 73. Compared with the lowest quartile, the multivariable-adjusted hazards ratios (95% confidence interval) for hypertension in the highest quartiles of changes in FT3, FT4, and TSH were 1.51 (1.23-1.84), 2.04 (1.67-2.48), and 1.20 (0.99-1.45), respectively. Similar relationships were observed between the means of FT3, FT4, TSH, and hypertension. However, we found no correlations between baseline FT3, FT4, TSH, and incident hypertension. The present study is the first to demonstrate that the annual changes and means, but not baseline FT3 and FT4 values are independently related to the risk of incident hypertension in the euthyroid general population.

Background Previous studies suggest that muscle-derived cytokines (myokines) are linked with brain function. Although muscle strength measured by handgrip strength is a prognostic indicator of functional decline, epidemiological studies directly examining the association between grip strength and mental health remain scarce. The aim of this study is to clarify the association between grip strength and depressive symptoms in the general adult population. Methods This is a cross-sectional study of 24,109 Chinese adults (41. 5 ± 11.9 years; 46.0% females). Grip strength was measured by dynamometer and the greatest force was normalized to body weight (NGS, kg/kg). Depressive symptoms were assessed using the Self-Rating Depression Scale (SDS). Models of logistic regression were conducted to assess the association between NGS and depressive symptoms, with adjustment for established confounding factors. Results Of the 24,109 participants, the prevalence of depressive symptoms (SDS ≥45) was 16.8% (males 15.7%, females 18.0%). After adjusting for multiple confounding factors, the odds ratios and 95% confidence interval for depressive symptoms in the quartiles of NGS were 1.00, 0.96 (0.84–1.10), 0.91 (0.79–1.05), and 0.91 (0.78–1.07) (P = 0.03) in males; 1.00, 0.92 (0.80–1.06), 0.90 (0.77–1.04), and 0.80 (0.69–0.94) (P = 0.0002) in females, respectively. Limitations This cross-sectional study cannot determine causality. Conclusions Grip strength was inversely associated with depressive symptoms, with stronger association observed among females than males. Further prospective studies or randomized trials are required to clarify these findings.

BACKGROUND Animal studies have shown that soy protein and isoflavones can increase antioxidant capacity and improve insulin resistance, and thus ameliorate nonalcoholic fatty liver disease (NAFLD). However, only limited epidemiological studies have examined the association of soy food intake with NAFLD. OBJECTIVES We investigated the association between soy food intake and NAFLD in a Chinese cohort. METHODS A total of 24,622 participants aged 20-90 y were included in the study. Diet information was collected using a validated 100-item FFQ. NAFLD was defined as having fatty liver diagnosed by ultrasonography and excluding men and women who consumed >210 g alcohol/wk and >140 g/wk, respectively. Logistic regression analysis was used to assess the association of soy food intake with NAFLD. RESULTS After adjustment for potential confounders, and taking those with

Research evidence supports a positive link between sugar-containing soft beverages and hyperuricemia. However, data thus far are mostly from Caucasian populations. And in sugar-containing soft beverages overall, sugar-containing carbonated beverages are purchased most often. Therefore, we investigated whether the high consumption of sugar-containing carbonated beverages was associated with the prevalence of hyperuricemia among adults in China.A cross-sectional study was conducted with 25,507 adults (13,013 men and 12,494 women) in Tianjin, China. Sugar-containing carbonated beverages intake was assessed by a validated semi-quantitative food frequency questionnaire. Hyperuricemia was defined as serum uric acid levels ≥7.0 mg/dL in men and ≥ 6 mg/dL in women. The association between carbonated beverages consumption and hyperuricemia was assessed by multiple logistic regression analysis. The prevalence of hyperuricemia in men and women was 23.4% and 8.2%, respectively. After adjustments for potential confounding factors, the odds ratios (95% confidence interval) for hyperuricemia across sugar-containing carbonated beverages consumption were 1.00 (reference) for almost never, 1.18 (1.05, 1.32) for1-3 cups/week, 1.49 (1.25, 1.77) for ≥4 cups/week in men (P for trend 0.005) and 1.11 (0.91, 1.34) for1-3 cups/week (P for trend = 0.27), 1.70 (1.23, 2.31) for ≥4 cups/week in women (P for trend0.001), respectively.This cross-sectional survey demonstrated that increased consumption of sugar-containing carbonated beverages is associated with hyperuricemia among adults in China. Restricted sugar-containing carbonated beverages intake might be beneficial to the prevention of hyperuricemia in the general population.

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome. Recent evidence has suggested the protective effects of honey consumption against the metabolic syndrome, but the association between honey intake and NAFLD is still unclear. We investigated how the consumption frequency of honey was associated with NAFLD in the general population. This was a cross-sectional study of 21 979 adults aged 20–90 years. NAFLD was diagnosed based on the ultrasound-diagnosed fatty liver without significant alcohol intake and other liver diseases. Diet information, including consumption frequency of honey, was assessed by a validated 100-item FFQ. OR with 95 % CI were calculated by the binary logistic regression model, adjusting for confounding factors identified by the directed acyclic graph. Overall, 6513 adults (29·6 %) had NAFLD. Compared with participants consuming ≤1 time/week of honey, the multivariable OR of NAFLD were 0·86 (95 % CI 0·77, 0·97) for 2–6 times/week and 1·10 (95 % CI 0·95, 1·27) for ≥1 times/d (Pfor trend = 0·90). The results were generally similar in subgroups of BMI at a cut-point of 24·0 kg/m2 (Pfor interaction = 0·10). In this large-scale study, consuming honey 2–6 times/week was inversely associated with NAFLD, whereas consuming honey ≥1 times/d had no association with NAFLD. These results need replication in other large-scale prospective studies.

Thyroid hormones (THs) have multiple effects on lipid synthesis, mobilization, and degradation, suggesting that THs may affect the development of dyslipidemia. However, prospective studies on the association between serum THs levels and incident dyslipidemia in euthyroid subjects are limited. Therefore, we conducted a cohort study (~5-year follow-up period, median: 3.0 years) to explore whether THs can affect incident dyslipidemia in a general euthyroid population aged 18 years old and over. Dyslipidemia is characterized by elevated total cholesterol (TC), triglyceride (TG), or low-density lipoprotein cholesterol (LDL-C), or reduced high-density lipoprotein cholesterol (HDL-C). Serum free triiodothyronine (FT3), free thyroxine (FT4), and thyroid-stimulating hormone (TSH) were determined by chemiluminescence immunoassay. Multivariable Cox proportional hazards regression models were used to assess the association between baseline FT3, FT4, TSH, and the risk of various dyslipidemias. During follow-up period, the incidence of elevated TC, TG, LDL-C, and reduced HDL-C was 29.3%, 20.7%, 24.8%, and 19.5%, respectively. After adjustment for multiple confounders, we found that per unit increase in FT3 concentrations were associated with decreased incidence of elevated TC and LDL-C, and the hazard ratios (95% confidence interval) were 0.87 (0.79–0.97) (P

Garlic-derived organosulfur compounds have numerous potential benefits (e.g. antioxidant and anti-inflammatory effects) on human health. Although these functions might be related to the onset and progression of muscle strength decline, no studies have explored the relationship between garlic consumption and muscle strength in the general population. The aim of this study was to investigate whether raw garlic consumption is related to handgrip strength in a large-scale adult population.A cross-sectional study (n = 28,958) was performed in Tianjin, China. Frequency of raw garlic consumption was assessed using a valid self-administered food frequency questionnaire. Handgrip strength was measured using a handheld digital dynamometer. Analysis of covariance and multiple logistic regression were used to evaluate the relationship between raw garlic consumption and handgrip strength.In males, after adjusted potential confounding factors, the least square means (95% confidence intervals) of handgrip strength across raw garlic consumption categories were 42.5 (40.2-44.9) for almost never; 43.0 (40.7-45.5) for1 time/week; 43.4 (41.0-45.8) for 1 time/week; and 43.8 (41.5-46.3) for ≥2-3 times/week (P for trend0.0001). The adjusted odds ratios (95% confidence intervals) of low handgrip strength (20th percentile of handgrip strength) across the categories of raw garlic consumption in males were 1.00, 0.86 (0.76, 0.98), 0.76 (0.67, 0.87), and 0.66 (0.58, 0.74) (P for trend0.0001). Similar results were also observed in females.The study firstly revealed a positive correlation between raw garlic consumption and handgrip strength in both males and females. Further studies are needed to explore the casual relationship.

A cross-sectional study was conducted to explore the association between soft drink consumption and handgrip strength (HGS) in subjects aged 40 years and older (n = 14,925). After multivariable-adj...

Banana contains many kinds of substances that are beneficial to depressive symptoms. However, there are no epidemiological researches directly to explore the association between banana consumption and depressive symptoms. This study aimed to investigate whether the banana consumption is related to depressive symptoms in a general adult population.A cross-sectional study was performed in 24,673 adults in Tianjin. Banana consumption was evaluated via a validated food frequency questionnaire. Depressive symptoms were assessed by using Self-Rating Depression Scale (SDS). The association between banana consumption and depressive symptoms was analyzed by multiple logistic regression analysis.The prevalence of depressive symptoms was 16.1% in males and 18.4% in females (SDS ≥ 45), respectively. In males, comparing to the reference group (almost never), the multivariable adjusted odds ratios (ORs) (95% confidence intervals) of depressive symptoms across banana consumption were 0.86 (0.74, 0.99) for1 time/week, 0.76 (0.66, 0.88) for 1-3 times/week and 0.97 (0.82, 1.16) for ≥4 times/week. By contrast, the multivariable adjusted ORs (95% confidence intervals) were 1.11 (0.94, 1.32) for1 time/week, 0.99 (0.85, 1.16) for 1-3 times/week and 1.22 (1.02, 1.46) for ≥4 times/week in females. Similar association was observed when other cut-offs (SDS ≥ 48 and 50) were used to define depressive symptoms.This is a cross-sectional study, causality remains unknown.Findings from this study suggested a negative association between moderate banana consumption and depressive symptoms in males. In females, high banana consumption is positively related to depressive symptoms.

Prospective cohort studies linking ultra-processed foods (UPF) and subclinical thyroid dysfunction (SCTD) are limited, especially in Chinese adults.

Prospective cohort studies linking organ meat consumption and nonalcoholic fatty liver disease (NAFLD) are limited, especially in Asian populations. This study aimed to prospectively investigate the association between organ meat consumption and risk of NAFLD in a general Chinese adult population. This prospective cohort study included a total of 15,568 adults who were free of liver disease, cardiovascular disease, and cancer at baseline. Dietary information was collected at baseline using a validated food frequency questionnaire. NAFLD was diagnosed by abdominal ultrasound after excluding other causes related to chronic liver disease. Cox proportional regression models were used to assess the association between organ meat consumption and risk of NAFLD. During a median of 4.2 years of follow-up, we identified 3,604 incident NAFLD cases. After adjusting for demographic characteristics, lifestyle factors, vegetable, fruit, soft drink, seafood, and red meat consumption, the multivariable hazard ratios (95% confidence intervals) for incident NAFLD across consumption of organ meat were 1.00 (reference) for almost never, 1.04 (0.94, 1.15) for tertile 1, 1.08 (0.99, 1.19) for tertile 2, and 1.11 (1.01, 1.22) for tertile 3, respectively (P for trend0.05). Such association did not differ substantially in the sensitivity analysis. Our study indicates that organ meat consumption was related to a modestly higher risk of NAFLD among Chinese adults. Further investigations are needed to confirm this finding.

Background Serum ferritin is an important iron storage protein in the human body, which indicates iron storage and the body’s nutritional status, and is associated with a variety of chronic diseases. Few prospective studies have assessed the association between serum ferritin levels and non-alcoholic fatty liver disease (NAFLD). This prospective cohort study aimed to explore whether serum ferritin levels were associated with the incidence of NAFLD in a large-scale adult population. Methods A total of 15,748 participants without baseline NAFLD were enrolled in the cohort study (1-9 years follow-up periods, median: 4.5 years). Serum ferritin levels were determined by protein chip-chemiluminescence method, and NAFLD was diagnosed by abdominal ultrasonography. Multivariable Cox proportional hazards regression models were used to assess the association between baseline serum ferritin levels and the risk of NAFLD. Results During the follow-up period, 3,374 new NAFLD cases were observed, and the incidence rate of NAFLD was 83.4 per 1000 person-years. In the fully adjusted model, the hazards ratios (95% confidence interval) for incident NAFLD across serum ferritin levels quartiles were 1.06 (0.94-1.19), 1.25 (1.11-1.41), and 1.52 (1.28-1.79) (P for trend

Wholegrain contributes a range of beneficial nutrients and is considered to play a role in the prevention of chronic diseases, but evidence of their influence on nonalcoholic fatty liver disease (NAFLD) is limited. We conducted this study to investigate the prospective association between daily wholegrain consumption and NAFLD in the general population.This prospective cohort study included a total of 14,968 (42.2% men) inhabitants living in Tianjin, China. Participants without a history of CVD, cancer, alcoholic fatty liver disease, other liver diseases, or NAFLD were followed up for 1-6 years with a median follow-up duration of 4.2 years. Wholegrain consumption was assessed using a validated self-administered food frequency questionnaire. NAFLD was diagnosed with the results of liver ultrasonography without significant alcohol consumption and other causes of liver disease. Cox proportional hazards regression models were used to estimate the association between wholegrain consumption and NAFLD.A total of 3505 (2171 men) first incident cases of NAFLD occurred during 53,303 person-years of follow-up (median follow-up of 4.2 years). After adjusting for several potential confounders and setting "almost never" as the control group, the multivariable hazard ratios (95% confidence intervals) of the NAFLD were 0.82 (0.73, 0.92) when they consuming ≤1 time/week, 0.78 (0.69, 0.88) when they consuming 2-6 time/week and 0.77 (0.66, 0.90) when they consuming ≥1 time/day (p for trend0.001).The results from our prospective study demonstrated that the higher consumption of wholegrain is associated with a decreased risk of NAFLD in Chinese adults.

Background Previous studies have posited that an association exists between thyroid function and the heart and vasculature. It remains unclear, however, whether longitudinal trends in thyroid function contribute to the development of atherosclerosis. We conducted a cohort study to examine the association of longitudinal trends in thyroid function with incident carotid atherosclerosis (CA) in middle-aged and older euthyroid subjects. Methods This cohort study’s participants were recruited from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study in Tianjin, China. Free triiodothyronine (FT3), thyroxine (FT4) and thyroid-stimulating hormone (TSH) were measured using chemiluminescence immunoassay. CA was assessed using carotid ultrasonography. Thyroid function and ultrasonography were assessed yearly during follow-up. Multivariable Cox proportional hazards regression models were used to assess the association between thyroid function and incident CA. Results A total of 3,181 participants were enrolled in the cohort study. Within 7,762 person-years of follow-up, 944 participants developed CA, the incidence rate of CA was 122 per 1,000 person-years. The fully adjusted hazards ratios (95% confidence interval) of CA for per 1-unit increase in changes of FT3, FT4 and TSH were 1.34(1.22–1.47), 1.22(1.19–1.26) and 0.92 (0.77–1.09) (P Conclusions These findings suggest that higher mean levels and higher values of changes in thyroid hormones were associated with a higher risk of incident CA in middle-aged and older euthyroid subjects.

This study aimed to evaluate the longitudinal association between sweet potato intake and risk of NAFLD in the general adult population. In total, the number of 15,787 participants (males, 42.4%) was included in this prospective cohort study. Sweet potato intake was assessed by using a validated food frequency questionnaire. NAFLD was diagnosed by transabdominal sonography during an annual health examination. Cox proportional hazards regression models were fitted to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) across categories of energy-adjusted sweet potato intake. Compared to participants with the lowest tertile of sweet potato intake, the finally adjusted HRs (95% CIs) of incident NAFLD for those with the highest tertile were 0.87 (0.78, 0.97) in males (p for trend = 0.009); and 1.05 (0.92, 1.21) in females (p for trend = 0.52). Our study revealed that sweet potato intake was inversely associated with the risk of NAFLD in males.

Non-alcoholic fatty liver disease (NAFLD) is a strong risk factor for type 2 diabetes. However, no study has investigated whether dietary intake can modify this effect. Therefore, we aimed to investigate the effect of dietary pattern modification on the association between NAFLD and type 2 diabetes.A large prospective cohort study (n = 24,602) was conducted in China. NAFLD was diagnosed using liver ultrasonography considering alcohol consumption. Dietary data were assessed using a validated self-administered food frequency questionnaire. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs).Following a 93,873 person-year follow-up, 787 (3.20%) participants developed type 2 diabetes. In a multivariable adjusted model, compared with participants without NAFLD, the HR (95% CI) of incident type 2 diabetes for NAFLD patients was 3.04 (2.51, 3.68). On subgroup analyses, the adjusted HRs (95% CIs) of incident type 2 diabetes for NAFLD patients with low (≤median score) and high (median score) vegetable pattern intakes were 4.08 (3.05, 5.46) and 2.38 (1.85, 3.07) (p for interaction0.01), respectively. Higher vegetable intake was also found to attenuate the risk effect of phenotype groups of NAFLD on incident type 2 diabetes, especially in the lean NAFLD group.The present study demonstrated that NAFLD is a strong risk factor for type 2 diabetes in the Chinese population. Notably, adherence to a dietary pattern rich in vegetables can attenuate this risk, especially in lean NAFLD patients.

Background: Timing the fixator removal is vital for a successful external fixation treatment. The purpose of this study was to determine the effectiveness of axial load-share ratio in vivo as a supplemental decision support tool for the safe removal of an Ilizarov external fixator.Methods: This prospective observational study consists of 83 patients undergoing tibial or femoral lengthening with Ilizarov circular external fixation in our institution, from January 2011 to October 2019. In group Ⅰ (38 patients), the external fixator was removed based on the surgeon’s clinical experience and radiographs from January 2011 to June 2015. In group Ⅱ (45 patients), from July 2015 to October 2019, the supplemental axial load-share (LS) ratio test was accomplished without the knowledge of the clinical results by another medical team. The test was performed by electronically measuring forces in the fixator rods and in a ground force plate. When the LS ratio < 10% was consistent with the conclusion (dense bone formation was achieved in the distraction zone) drawn from the corresponding routine radiographs by the treating surgeon, the external fixator was removed.Results: There was no statistical significance in demographic data between the two groups (P>0.05). In group Ⅰ, 4 of the 38 patients suffered refracture (the refracture rate was 10.5%) after fixator removal, and bone union was finally achieved with further intervention by intramedullary nail. In group Ⅱ, 36 patients terminated the external fixation after the first mechanical test, and another 9 patients terminated the external fixation at the subsequent test. None of the 45 patients in group Ⅱ suffered refracture (the refracture rate was 0%). There was statistical significance in the refracture rate between the two groups (PConclusions: Adequate assessment of bone regenerate is crucial before removing an external fixator to prevent deformation or refracture. The axial load-share ratio in vivo is a practically quantitative method to supplement radiography and clinical experience for the assessment of regenerate healing, and the axial load-share ratio dropped below 10% is a safe limit for the Ilizarov external fixator removal.

Background: Basic studies have found that xanthine oxidase inhibitors extracted from mushrooms have inhibitory effects on hyperuricemia. However, the association between mushroom consumption and hyperuricemia is unknown in humans. Objective: We therefore designed a large-scale cohort study to examine whether mushroom consumption is a protective factor for developing hyperuricemia in adults. Methods: This prospective cohort study investigated 19 830 participants (mean age: 39.4 years; and 9906 [50.0%] men) who were free of hyperuricemia, cardiovascular disease, and cancer at the baseline. Mushroom consumption was measured at the baseline using a validated food frequency questionnaire. Hyperuricemia is defined as serum uric acid levels >420 μmol L−1 in men and >350 μmol L−1 in women. Cox proportional hazards regression models were used to examine the association of mushroom consumption with incident hyperuricemia. Restricted cubic spline regression was used to estimate the dose–response relationship between mushroom consumption and risk of hyperuricemia. Results: A total of 4260 first incident cases of hyperuricemia occurred during 61 421 person-years of follow-up (median follow-up of 4.2 years). After adjusting for demographic characteristics, lifestyle factors, dietary intake, and inflammatory markers, the multivariable hazard ratios (95% confidence intervals) for incident hyperuricemia were 1.00(reference) for 5.52 g per 1000 kcal per day, respectively (P for trend = 0.007). Conclusions: This population-based prospective cohort study has firstly demonstrated that higher mushroom consumption is significantly associated with lower incidence of hyperuricemia among general adults.

Background: The existing approaches to treating elbow fractures include anterior, external, internal, and posterior approaches. Of these, the anterior approach is often not chosen by surgeons to avoid damaging important nerves and blood vessels. In fact, the anterior approach has unique advantages. The purpose of this study was to report the outcomes in 38 patients with coronal plane elbow fractures treated through the anterior approach.Methods: We retrospectively analyzed 38 cases of coronal plane elbow fractures treated through an anterior approach at our institution between March 2015 and July 2019. The length of the surgical incision, operation time, intraoperative blood loss, and postoperative complications were recorded. The range of flexion, extension, and rotation of the affected elbow and the healthy elbow were collected at follow-up. Functional outcomes were evaluated using the Mayo Elbow Function Score (MEPS).Results: All 38 patients were followed up. At the final follow-up, solid osseous union was confirmed for all coronal plane elbow fractures. The mean elbow flexion arc was 129.26 ± 6.9 degrees, and the extension arc was 8.87 ± 6.13 degrees. The mean pronation arc was 83.45 ± 2.9 degrees, and the supination arc was 80.05 ± 2.92 degrees. The mean MEPS was 90.0±7.53 points, with 18 excellent cases and 20 good cases. There was no significant difference in elbow extension, flexion, and pronation between 31 cases of single fracture and the healthy elbow (P > 0.05); the arc of supination was slightly worse than that of the healthy elbow (P < 0.05). The VAS pain scores of the patients before the operation, three months after the operation, and during follow-up were compared. The pain of the patients was significantly reduced after treatment (P < 0.05). Two patients experienced transient postoperative median nerve paralysis, from which they recovered within three months. One patient had mild heterotopic ossification and was not treated because it did not affect the function of the elbow joint. All patients returned to work and were satisfied with the treatment.Conclusion: The anterior approach has the benefits of simplicity, safety, minimal invasion, excellent exposure, and satisfactory prognosis for coronal plane elbow fracture.

High dietary fibre intake has been associated with a lower risk of diabetes, but the association of dietary fibre with prediabetes is only speculative, especially in China, where the supportive data from prospective studies are lacking. This study aimed to examine the association between dietary fibre intake and risk of incident prediabetes among Chinese adults. We performed a prospective analysis in 18 085 participants of the Tianjin Chronic Low-grade Systemic Inflammation and Health cohort study who were free of diabetes, prediabetes, cancer and CVD at baseline. Dietary data were collected using a validated 100-item FFQ. Prediabetes was defined based on the American Diabetes Association diagnostic criteria. Cox proportional hazard models were used to estimate hazard ratios (HR) and 95 % CI. During 63 175 person-years of follow-up, 4139 cases of incident prediabetes occurred. The multivariable HR of prediabetes for the highest v. lowest quartiles were 0·85 (95 % CI 0·75, 0·98) (P for trend = 0·02) for total dietary fibre, 0·84 (95 % CI 0·74, 0·95) (P for trend < 0·01) for soluble fibre and 1·05 (95 % CI 0·93, 1·19) (P for trend = 0·38) for insoluble fibre. Fibre from fruits but not from cereals, beans and vegetables was inversely associated with prediabetes. Our results indicate that intakes of total dietary fibre, soluble fibre and fibre derived from fruit sources were associated with a lower risk of prediabetes.

Background Previous studies have reported that tea extract supplementation has potential benefits on the risk factors of non-alcoholic fatty liver disease (NAFLD); however, no study has investigated the direct effect of daily tea consumption on the prevalence of NAFLD in the general population. This cross-sectional study aimed to evaluate the associations between tea consumption and the prevalence of newly diagnosed NAFLD among Chinese adults. Methods The present cross-sectional study was based on the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. In total, 19,350 participants were enrolled in the analyses. Tea consumption was assessed via a self-administered food frequency questionnaire. NAFLD was diagnosed via liver ultrasonography and no history of heavy alcohol intake. Logistic regression analysis was used to estimate the associations between tea consumption and the prevalence of NAFLD. Results Consumption of green tea, oolong tea, and black tea were positively associated with the prevalence of newly diagnosed NAFLD before adjustments. Compared with the participants who never drink tea, the odds ratios (95% confidence interval) of newly diagnosed NAFLD in the highest categories (≥ 1 cup/day) of green tea, oolong tea, black tea, and jasmine tea were 1.48 (1.33, 1.65), 1.50 (1.33, 1.68), and 1.28 (1.13, 1.46), and 1.36 (1.20, 1.54) before adjustments, respectively. However, no significant association was found between tea consumption and the prevalence of NAFLD after adjusting for socio-demographic, behavioural, anthropometric, dietary, and clinical confounding factors. Conclusion There is no significant association between daily tea drinking and newly-diagnosed NAFLD in general Chinese adults.

Background/Objectives Many studies have suggested that probiotics may be applied as a therapeutic agent for non-alcoholic fatty liver disease (NAFLD). However, the effects of frequent yogurt consumption (as a natural probiotic source) on NAFLD remain poorly understood. This study was to examine the association of habitual yogurt consumption with newly diagnosed NAFLD in the general adult population. Subject/Methods Overall, 24,389 adults were included in this cross-sectional study. Yogurt consumption was estimated by using a validated self-administered food frequency questionnaire. NAFLD was diagnosed by abdominal ultrasonography. We used logistic regression models to assess the association between yogurt consumption categories and newly diagnosed NAFLD. Results The multivariable odds ratios with 95% confidence interval of newly diagnosed NAFLD were 1.00 (0.88, 1.14) for 1 time/week, 0.91 (0.81, 1.02) for 2–3 times/week, and 0.86 (0.76, 0.98) for ≥4 times/week (P for trend = 0.01), compared with those who consumed Conclusion Higher yogurt consumption was inversely associated with the prevalence of newly diagnosed NAFLD. These results are needed to be confirmed in randomized controlled trials or prospective studies.

Background and aims Metabolic syndrome (MetS) is a combination of metabolic disorders that increase the risk of developing cardiovascular disease, and inflammation is considered as a pathological basis for MetS. Immunoglobulins (Igs) are the major secretory products of the adaptive immune system. However, no large-scale population study has focused on a possible relationship between Igs and MetS. We designed a cross-sectional study to investigate the relationship between Igs and prevalence of MetS in a large-scale adult population. Methods and results A total of 10,289 participants were recruited among residents in Tianjin, China. Metabolic syndrome was defined in accordance with the criteria of the American Heart Association scientific statements of 2009. Serum levels of Igs were determined by immunonephelometry. Multiple logistic regression models were used to assess the relationship between the quintiles of serum levels of Igs and the prevalence of MetS. The overall prevalence of MetS was 36.1%. The mean (standard deviation) values of Igs (IgG, IgE, IgM, and IgA) were 1205.7 (249.3) mg/dL, 93.1 (238.9) IU/mL, 105.7 (57.3) mg/dL, and 236.2 (97.6) mg/dL, respectively. The adjusted odds ratios (95% confidence interval) of MetS for the highest quintile of Igs (IgG, IgE, IgM, and IgA), when compared to the lowest quintile, were 0.81 (0.70, 0.95), 0.97 (0.83, 1.12), 1.13 (0.97, 1.33), and 1.52 (1.30, 1.77), respectively. Conclusions This study demonstrated that decreased IgG and increased IgA are independently related to a higher prevalence of MetS. The results indicate that the Igs might be useful predictive factors for MetS in the general adult population.

BACKGROUND Red blood cell distribution width (RDW) was related with increased risk of mortality and adverse cardiovascular outcomes. However, it is uncertain whether RDW is related to the prevalence of atrial fibrillation (AF) in Asian population. The aim of this study was to assess the relationship between RDW and AF in a large Chinese population. METHODS We performed a cross-sectional study to examine the relationship between RDW and AF among 106 998 subjects who were from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. AF was diagnosed using electrocardiography, and RDW was measured using an automated hematology analyzer. Multiple logistic regression models were conducted to examine the relation between tertiles of RDW and AF. RESULTS The overall prevalence of AF was 0.1% (129/106 998). After adjustments for potential confounding factors, the odds ratios (95% confidence intervals) of AF across increasing tertiles of RDW were 1.00 (reference), 1.08 (0.69, 1.67), and 2.65 (1.75, 4.07) (P for trend

Context Thyroid hormones (THs) have direct and indirect effects on hematopoiesis. However, few studies have directly evaluated the effect of THs on incident anemia among euthyroid subjects. This cohort study aimed to explore whether THs under physiological conditions can affect the development of anemia in the general population. Design A total of 12,310 participants were enrolled in the cohort study (∼5-year follow-up period; mean, 3.1 years). A chemiluminescence immunoassay was used to measure free T3 (FT3), free T4 (FT4), and TSH, and anemia was defined according to the World Health Organization recommendation. THs, TSH, and Hb were assessed yearly during follow-up. Multivariable Cox proportional hazards regression models were used to assess the association between THs, TSH, and incident anemia. Results The fully adjusted hazards ratios (95% CI) of anemia per 1-unit change in FT3, FT4, and TSH concentrations were 0.70 (0.56, 0.87), 0.93 (0.88, 0.98), and 1.19 (0.94, 1.50) (P < 0.01, P < 0.01, and P = 0.14, respectively). Moreover, a significant and positive association between FT3, FT4, and annual changes in Hb (standard regression coefficients of 0.056 and 0.028, respectively; both P < 0.01) was observed. Similar associations were observed when the participants who had thyroid dysfunction upon follow-up were excluded. Conclusions The current study demonstrated that THs significantly predict future anemia and annual changes in Hb, even in the euthyroid population.

Many components in diet have regulated oxidative stress, inflammatory reaction and even balance oestrogen levels. Because these factors are closely associated with depressive symptoms in postmenopausal women, it is considered that dietary factors are able to prevent and control depressive symptoms. On the other hand, a dietary pattern that considers the correlations and synergies between foods and nutrients is expected to have a greater impact on disease risk. The aim of the present study is to evaluate whether dietary patterns are associated with depressive symptoms in Chinese postmenopausal women. A cross-sectional study of 2051 postmenopausal women (mean age: 58·8 (sd 7·4) years) was conducted in Tianjin, China. Dietary consumption was assessed by a valid self-administered FFQ. Principal component analysis was used to derive three major dietary patterns: ‘healthy’, ‘sweets’ and ‘traditional Tianjin’ from eighty-eight food items. Depressive symptoms were assessed using the Zung Self-Rating Depression Scale, and cut-off point of 48 indicating serious depressive symptoms. The association between quartile of dietary patterns and depressive symptoms was assessed using multiple logistic regression analysis. The multivariable-adjusted OR of having depressive symptoms for increasing quartile of dietary patterns were as follows: healthy, 1·00, 0·79 (95 % CI 0·49, 1·28), 0·62 (95 % CI 0·37, 1·04) and 0·57 (95 % CI 0·33, 0·97); sweets, 1·00, 0·75 (95 % CI 0·42, 1·3), 1·08 (95 % CI 0·64, 1·81) and 1·66 (95 % CI 1·03, 2·71); and traditional Tianjin, 1·00, 1·02 (95 % CI 0·58, 1·79), 0·96 (95 % CI 0·54, 1·71) and 2·53 (95 % CI 1·58, 4·16), respectively. The present study demonstrated that a healthy dietary pattern was inversely associated with depressive symptoms. On the contrary, greater adherence to sweets and traditional Tianjin dietary patterns was associated with a higher prevalence of depressive symptoms.

Prediabetes has been a growing health problem in China, and it is a high-risk state for developing diabetes and cardiovascular disease. In previous studies, low grip strength has been associated with diabetes. However, few population-based studies have examined the relationship between grip strength and prediabetes. Thus, the purpose of this study was to investigate whether grip strength is related to prediabetes in a large-scale adult population.A total of 27,295 participants aged 20 to 90 years were included from the 2013-2016 Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. Grip strength was assessed using an electronic hand-grip dynamometer and the greatest force was normalized to body weight. Prediabetes was diagnosed based on the American Diabetes Association criteria. Multiple logistic regression analysis was conducted in 2018 to assess the relationship of grip strength to the prevalence of prediabetes, while controlling for age, BMI, smoking, drinking, physical activities, dietary patterns, and other confounders.Of the 27,295 participants, 28.5% (7,783) had prediabetes. After adjusting for potential confounders, a one unit increase in grip strength per body weight was associated with 52% lower odds of having prediabetes for men (OR=0.48, 95% CI=0.30, 0.74, p0.01) and 62% lower odds of having prediabetes for women (OR=0.38, 95% CI=0.20, 0.70, p0.01).Increased grip strength is independently associated with lower prevalence of prediabetes in Chinese adults, suggesting that grip strength may be a useful marker for screening individuals at risk of prediabetes.

Objectives Non-alcoholic fatty liver disease (NAFLD) is one of the most common public health issues worldwide. Oranges are the most popular fruit consumed in the world. Admittedly, flavonoids in oranges act as antioxidants and improve liver steatosis. However, oranges also are rich in fructose, which is a risk factor in the progress of NAFLD. Therefore, we hypothesize that orange intake may be a double-edged sword in the development of NAFLD. To our knowledge, there currently is little evidence of the effect of dietary orange intake on NAFLD. The aim of this study was to investigate how orange intake is related to NAFLD in a general adult population. Methods We randomly recruited 27,214 adults into the Tianjin Chronic Low-Grade Systemic Inflammation and Health Cohort Study. NAFLD was diagnosed by liver ultrasonography. Raw orange intake was assessed by a validated self-administered food frequency questionnaire. Multiple logistic regression analysis was used to evaluate the association between orange intake and the prevalence of NAFLD. Results There was a 27.18% prevalence of NAFLD among the participants. Consumption of orange was positively associated with the prevalence of NAFLD after adjustment for all potential confounding factors (Ptrend = 0.04). The odds ratios (95% confidence interval) of the categories of orange intake in the NAFLD were 1.00 (reference) for less than once per week, 1.02 (0.95–1.11) for 1 to 6 times per week, and 1.17 (1.03–1.33) for ≥7 times per week, respectively. Conclusions The present study demonstrated that orange intake is positively associated with the prevalence of NAFLD.
