Background: Adolescence is a unique stage of life accompanied by physiological and psychological modifications, along with stress, confusion, and depression. Materials and methods: The present descriptive-analytical cross-sectional research was done on 267 male adolescents who studied at high schools in Zanjan, Iran. Demographic characteristics questionnaires, a 48-item food frequency questionnaire, a short version of the International Physical Activity Questionnaire (IPAQ), the Depression Anxiety Stress Scale (DASS-21), and the Pittsburgh Sleep Quality Index (PSQI) were used to collect data. Results: The mean ± standard deviation (SD) of age, weight, height, and sitting time was 15.94 ± 0.91 years, 68.53 ± 15.28 kg, 1.75 ± 0.06 m, and 449.25 ± 322.06 min, respectively. The study results showed that students with poor sleep quality showed a higher rate of depression than those with good sleep quality in the high and low physical activity groups (p < 0.05). The stress, depression, and anxiety scores significantly correlated with sleep quality in the physical activity groups (p < 0.05). The structural equation model analysis results showed that mental health directly affected sleep quality; this association was significant in the low physical activity group. Conclusion: We found that sleep quality was independently related to mental health in young Iranian men. However, dietary intake was not a significant predictor of mental health or sleep quality. More studies are required to evaluate the association between dietary intake and sleep quality in adults. [ABSTRACT FROM AUTHOR]

Background/Objectives: Very low birth weight (VLBW) infants may require enhanced nutrition, even during complementary feeding. However, there are limited data on macronutrient intake during this period, particularly concerning the individual timing of the introduction of solid foods in a representative VLBW infant population. Methods: This prospective observational study analyzed macronutrient intake in VLBW infants with a gestational age < 32 weeks based on whether solid foods were introduced early (<17 weeks corrected age (CA)) or late (≥17 weeks corrected age) Nutritional intake was analyzed using a 24 h recall at 6 weeks CA and 3-day dietary records at 12 weeks, 6, 9, and 12 months CA. Results: In total, 115 infants were assigned to the early and 82 to the late group. The timing of solid food introduction did not affect macronutrient intake, except for a lower fat and higher carbohydrate intake (% of energy) in the early group at 12 weeks and 6 months CA: early vs. late, fat—12 weeks: 47.0% vs. 49.0%, 6 months: 39.2% vs. 43.3%; carbohydrates—12 weeks: 44.9% vs. 43.2%, 6 months: 51.3% vs. 48.0%. Apart from docosahexaenoic acid (DHA) and arachidonic acid (AA), dietary intake recommendations were met in both groups. While nutrient intakes varied significantly between breastfed and formula-fed infants, those with comorbidities exhibited similar nutrient intake levels compared to those without. Conclusions: Our findings suggest adequate macronutrient intakes in VLBW infants irrespective of the timing of solid introduction. However, there is a notable need to enhance dietary intakes of DHA and AA. Future research is crucial to assess whether current nutrient intakes are sufficient for VLBW infants with comorbidities.

To evaluate the influence of early nutritional intake on the growth pattern of very preterm infants. This was an observational study including 109 newborns (< 32 weeks gestational age). Perinatal morbidities, nutritional therapy (first four weeks of life), and weight, length, and head circumference (HC) growth at term-equivalent age were evaluated. Growth restriction was defined as a difference > 1.2 SD between the birth and term age measurements. Growth restriction at term-equivalent age: 52.3% (weight), 42.9% (length), and 22% (HC). Morbidities were positively correlated with nutrition therapy and negatively correlated with the total energy provision: protein ratio. The duration of parenteral nutrition, the time to reach full enteral feedings, and the total energy provision: protein ratio were significantly correlated. Nutrient intake influenced weight, length, and HC growth, and cumulative energy deficit was significantly associated with HC growth restriction. Conclusion: Perinatal morbidities interfere with nutritional therapy and early nutrient intake, leading to insufficient energy and energy provision: protein ratio for growth. What is Known: • The intake of macronutrients early in life, mainly protein, is important for the optimal growth of pretem infants. • The severity of morbidities and low gestational ages impact the nutritional management of preterm infants. What is New: • The number of morbidities, reflecting the severity of the neonatal clinical course, had a detrimental effect on the nutritional therapy and nutrients intake. • The inadequate energy provision per gram of protein ratio was significantly associated with growth restriction in all growth measures at the second week of life, persisting for head circumference up to the fourth week, highlighting the importance of its measurement, as it could be a precocious sign of development risk.

Orofacial clefts (OFC) are the most common congenital malformation of the craniofacial skeleton. Attempts have been made to correlate the components of maternal diet as triggers for the development or prevention of OFC. To analyze nutritional status as a predictive factor for the development of cleft lip and palate in an Amazonian population. A total of 152 mothers within 3 months of delivery were interviewed for comparison: 51 mothers of children with nonsyndromic cleft lip and palate (CLP) (study group) and 101 mothers of children without OFC (control group). A food frequency questionnaire was used to assess maternal nutrition and to analyze the influence of macro- and micronutrients on the possible predisposition or protection for CLP. The study group showed higher percentage of lipid intake than did the control group (p = 0.01). Among the participants with no family history of OFC, the study group had a higher percentage of lipid intake (p = 0.002) and lower vegetable intake (p = 0.037). Maternal micronutrient intake among the participants with a positive family history was lower in the study group for vitamins B2 (p = 0.03), B5 (p = 0.036), E (p = 0.03), and folate (p = 0.022). Nutritional analysis indicated that higher maternal lipid intake increased the likelihood of having offsprings with nonsyndromic CLP. Moreover, families with a history of OFC and low maternal folate intake showed heightened risk of nonsyndromic CLP in their offsprings. [ABSTRACT FROM AUTHOR]

This study aimed to determine changes in energy and nutrient intakes over three consecutive days, including the day of the shift, and the days before and after the shift, in healthcare workers working in a 24 h shift system. This study is an observational follow-up study conducted with a total of 500 volunteer healthcare professionals. Food consumption records were taken over 3 consecutive days: pre-shift (off day), shift day (24 h shift), and post-shift (off day). Mean daily intakes of energy, carbohydrate, protein, fat, saturated fat, caffeine, vitamins B1 , B2 , niacin, B6 , folate, and B12, potassium, magnesium, phosphorus, iron, and zinc are listed from highest to lowest as shift day > pre-shift > post-shift (p < 0.05 for all pairwise comparisons). While fiber, vitamin C, and calcium intakes were similar on the shift day and pre-shift day, they were significantly lower on the post-shift day (p < 0.05). The lowest dietary reference intake percentages on the post-shift day were calcium, fiber, and folate, respectively. In the present study, significant differences were detected in the energy, micronutrient-intake, and macronutrient-intake levels between the pre-shift day, shift day, and post-shift day of healthcare workers. Awareness should be increased regarding the decreased nutrient intake seen especially on the first day after a 24 h shift, and appropriate precautions should be taken to increase calcium, fiber, and folate intake levels.

Background: Female obesity prevalence was higher than male in 2018 at 44.4% and 26.6%, respectively, according to Badan Pusat Statistik (BPS). There is conflicting evidence on the effect of hormonal contraception on weight gain. While in Indonesia, hormonal contraception has been the most popular method. Objectives: Examining the association between hormonal contraception usage, macronutrient consumption, and nutritional status. Methods: This cross-sectional study involves 106 non-pregnant women aged 20-45 recruited using consecutive sampling methods. Respondents were grouped into hormonal and non-hormonal contraceptive users. Data analysis utilized chi-square, Fischer exact and multiple linear regression. Results: More than half (59.5%) used hormonal contraception, while 40.5% used nonhormonal contraceptives. We found no significant correlation between hormonal contraception and Body Mass Index (BMI) (p-value=0.081), waist circumference (pvalue=0.789), and macronutrient intake (p-value of energy=0.0675; protein=0.758; fat=0.156; carbohydrate=0.23). There was no significant relationship between the duration of contraceptive usage and BMI (p-value=0.163 and 0.248) or waist circumference (p-value=0.282 and 0.066) for either users or nonusers. Linear regression models showed that only fat and carbohydrate intake significantly contribute to waist circumference (The adjusted R2 of the model was 0.244, F 12.3, Sig.<0.001) and BMI (The adjusted R2 of the model was 0.206, F 7.8, Sig.<0.001). Conclusions: There was a relationship between BMI, body fat percentage, junk food consumption pattern (type, frequency, amount of intake and fat), energy intake, fat intake, emotional overeating, diet attitude, and oral control of the abdominal circle. There was no significant relationship between fiber intake and abdominal circumference. [ABSTRACT FROM AUTHOR]

Abstract Background Despite the positive impact of trade liberalization on food availability in India, severe inequality in nutrition consumption at the district level persists. Empirical evidence on the relationship between trade liberalization and nutrition consumption inequality often offers a country-level perspective and generates disputed outcomes. The study aimed to explore the effects of trade liberalization on inequality in nutrition consumption at the district level in India and to examine the heterogeneity of the impact on different nutrition consumption. Methods Our study employed the Gini Index to measure nutrition consumption inequality of 2 macronutrients and 5 micronutrients at the district level in India during 2009–2011, utilizing the comprehensive FAO/WHO individual food consumption data. The import tariff was adopted as a proxy for trade liberalization, as its externally imposed nature facilitates a causal interpretation. We further identified the direct causal relationship between food trade liberalization and inequality in nutrition consumption using a fixed effects model. Results The results show that more than 50% of the individuals in the survey districts did not meet the dietary standards for both macronutrients and micronutrients. Food trade liberalization hindered the improvement of inequality in nutrition consumption. As import tariffs were reduced by 1%, the inequality in intake of calories, zinc, vitamin B1, and vitamin B2 increased significantly by 0.45, 0.56, 0.48, and 0.66, respectively, which might be related to food market performance. The results also highlight the positive role of the gender gap, female-headed households, and caste culture on inequality in nutrition consumption in India. Conclusions To ease the shock of liberalization and minimize its inequality effects, complementary measures should be adopted, such as improving food logistic conditions in poor areas, and nutrition relief schemes.

Background Sports nutrition is an impactful component to sports performance. The purpose of the current study was to investigate the sports nutrition knowledge of National Collegiate Athletic Association collegiate athletes and assess self-reported perceived requirements for energy and macronutrient intake. A secondary aim was to evaluate the awareness of physical and emotional perceptions associated with mindful eating.Methods Participants included NCAA Division I (DI, n = 45), II (DII, n = 31), and III (DIII, n = 47) athletes. Athletes completed a validated questionnaire designed to assess sports nutrition knowledge and were asked questions about their perceived dietary energy and macronutrient requirements. Daily energy intake values were calculated using a recommended relative energy intake value of 40, 50, and 60 kcal/kg/day for low, moderate, and high activity levels, respectively. Carbohydrate recommendations were calculated using 4, 6, and 8 g/kg/day, protein recommendations were calculated using relative intakes of 1.4, 1.6, and 1.8 g/kg/day, and fat recommendations were calculated from a relative percentage of total predicted daily energy requirements, equating to 15, 25, and 30% of daily energy. Additionally, athletes completed a questionnaire to assess mindfulness regarding eating habits.Results Overall, athletes answered 45.5 ± 13.5% of questions correctly on the nutrition questionnaire with significant differences observed between male (48.6 ± 13.6%) and female athletes (43.6 ± 13.2%; p = 0.044), as well as significant differences observed between DI athlete scores (38.8 ± 14.1%) and DII athletes (47.7 ± 11.4%; p = 0.002), and DI athletes and DIII athletes (51.71 ± 11.83%; p =

Fat mass and obesity-related (FTO) gene single nucleotide polymorphisms (SNPs) interferes with food preferences that impact macronutrient intake. Few studies have investigated the relationship of this polymorphisms with the intake of micronutrients. Moreover, studies have shown multiple micronutrient deficiencies in patients with obesity. This work evaluated the effect of the FTO rs9939609 gene polymorphism on dietary nutritional quality and food intake of macronutrients and vitamins in of women with obesity candidates for metabolic surgery. The study included 106 women (24 to 60 years old) with BMIs of 36.1 to 64.8 kg/m2. A food frequency questionnaire validated for the local population was applied to obtain information about food intake. The Index of Nutritional Quality (INQ) was used to assess the adequacy of macronutrient and vitamin intake. Energy, protein and lipid intakes were higher in carriers of the A allele compared to TT in the younger age groups but were similar in the class of subjects aged ≥45 years. The INQ for protein was higher in carriers of the A allele than in carriers of the TT allele. The INQs for protein, carbohydrate, vitamins B2, B3 and B6 decreased, whereas the INQ for vitamin C increased with advancing age. The INQ for vitamin A was lower in AA than in TT, regardless of age, whereas vitamin E was higher in younger AA than in older AA. The INQ for vitamin B9 was higher in younger women than in older women. In conclusion, the FTO gene contributed to the intake of more energy, protein and lipids and interfered with the intake of vitamins B9, A and E. With the exception of vitamin A, the effect of the genotype was attenuated with ageing.

The effects of increasing Internet use in developing economies have attracted various attention from politicians and academic researchers, while the literature investigating the effects of Internet use on nutrition and health is insufficient. In particular, research on China, with its large overweight population, is still not clear and complete. This study aims to evaluate the effect of Internet use on body mass index (BMI) and overweight for males in China and shed light on the underlying mechanisms of the effect. To address the non-random distribution problem of Internet use and control for unobservable factors that might bias the estimates we are interested in, an endogenous switching regression model is applied, an econometric method in which counterfactual analysis is used to obtain the average treatment effect of Internet use on BMI and overweight. The study sample is chosen from longitudinal research data from the China Health and Nutrition Survey, with 12,846 observations covering 5 waves. Estimation results indicate that Internet use could reduce BMI and the probability of being overweight by 3.626% and 33.963%, respectively. Heterogeneity analysis shows that Internet use has a greater effect on males living in urban areas and those with higher education. We also reveal that reducing total energy intake and macronutrient intake and increasing dietary knowledge levels and the time spent on exercising serve as important mechanisms through which Internet use can have an effect on BMI and overweight. This study shows that Internet use has a beneficial effect on BMI and overweight of males in China. Therefore, internet platforms may be an effective way to regulate males’ macronutrient intake and BMI and overweight. More importantly, using Internet platforms to circulate information about healthy diets may contribute to improving dietary knowledge and the prevalence of overweight.

ObjectiveTo explore the relationship between macronutrient intake and sleep quality， the current sleep quality of pregnant women from ten cities in China was investigated.MethodsMultistage stratified sampling was used to investigate the nutrient intake and sleep quality of 863 pregnant women in ten Chinese cities. Twenty-four dietary intake， sleep quality， perinatal depression， and other information was obtained using physical measurements and a questionnaire. Logistic and multiple linear regression models were used to explore the relationship between macronutrient intake and sleep quality.ResultsThe prevalence of poor sleep quality among pregnant women was 46.12%； pregnant women who were in the third trimester， who had depression， were currently unemployed， passively smoked during pregnancy， and had a history of previous alcohol consumption， demonstrated a higher levels of poor sleep quality （P

Abstract Objective: Diets with a low proportion of energy from protein have shown to cause overconsumption of non-protein energy, known as Protein Leverage. Older adults are susceptible to nutritional inadequacy. The aim was to investigate associations between protein to non-protein ratio (P:NP) and intakes of dietary components and assess the nutritional adequacy of individuals aged 65–75 years from the Nutrition for Healthy Living (NHL) Study. Design: Cross-sectional. Nutritional intakes from seven-day weighed food records were compared with the Nutrient Reference Values for Australia and New Zealand, Australian Guide to Healthy Eating, Australian Dietary Guidelines and World Health Organisation Free Sugar Guidelines. Associations between P:NP and intakes of dietary components were assessed through linear regression analyses. Setting: NHL Study. Participants: 113 participants. Results: Eighty-eight (59 female and 29 male) with plausible dietary data had a median (interquartile range) age of 69 years (67–71), high education level (86 %) and sources of income apart from the age pension (81 %). Substantial proportions had intakes below recommendations for dairy and alternatives (89 %), wholegrain (89 %) and simultaneously exceeded recommendations for discretionary foods (100 %) and saturated fat (92 %). In adjusted analyses, P:NP (per 1 % increment) was associated with lower intakes of energy, saturated fat, free sugar and discretionary foods and higher intakes of vitamin B12, Zn, meat and alternatives, red meat, poultry and wholegrain % (all P < 0·05). Conclusions: Higher P:NP was associated with lower intakes of energy, saturated fat, free sugar and discretionary. Our study revealed substantial nutritional inadequacy in this group of higher socio-economic individuals aged 65–75 years.

Background/Objectives: Very low birth weight (VLBW) infants may require enhanced nutrition, even during complementary feeding. However, there are limited data on macronutrient intake during this period, particularly concerning the individual timing of the introduction of solid foods in a representative VLBW infant population. Methods: This prospective observational study analyzed macronutrient intake in VLBW infants with a gestational age < 32 weeks based on whether solid foods were introduced early (Results: In total, 115 infants were assigned to the early and 82 to the late group. The timing of solid food introduction did not affect macronutrient intake, except for a lower fat and higher carbohydrate intake (% of energy) in the early group at 12 weeks and 6 months CA: early vs. late, fat—12 weeks: 47.0% vs. 49.0%, 6 months: 39.2% vs. 43.3%; carbohydrates—12 weeks: 44.9% vs. 43.2%, 6 months: 51.3% vs. 48.0%. Apart from docosahexaenoic acid (DHA) and arachidonic acid (AA), dietary intake recommendations were met in both groups. While nutrient intakes varied significantly between breastfed and formula-fed infants, those with comorbidities exhibited similar nutrient intake levels compared to those without. Conclusions: Our findings suggest adequate macronutrient intakes in VLBW infants irrespective of the timing of solid introduction. However, there is a notable need to enhance dietary intakes of DHA and AA. Future research is crucial to assess whether current nutrient intakes are sufficient for VLBW infants with comorbidities.

Many epidemiological studies have evaluated the intake of macronutrients and the risk of mortality and cardiovascular disease (CVD). However, current evidence is conflicting and warrants further investigation. Therefore, we carried out an umbrella review to examine and quantify the potential dose-response association of dietary macronutrient intake with CVD morbidity and mortality. Prospective cohort studies from PubMed, Embase, and CENTRAL were reviewed, which reported associations of macronutrients (protein, fat, and carbohydrate) with all-cause, CVD, cancer mortality, or CVD events. Multivariable relative risks (RR) were pooled, and heterogeneity was assessed. The results of 124 prospective cohort studies were included in the systematic review and 101 in the meta-analysis. During the follow-up period from 2.2 to 30 years, 506,086 deaths and 79,585 CVD events occurred among 5,107,821 participants. High total protein intake was associated with low CVD morbidity (RR 0.88, 95% confidence interval 0.82–0.94), while high total carbohydrate intake was associated with high CVD morbidity (1.08, 1.02–1.13). For fats, a high intake of total fat was associated with a decreased all-cause mortality risk (0.92, 0.85–0.99). Saturated fatty acid intake was only associated with cancer mortality (1.10, 1.06–1.14); Both monounsaturated fatty acid (MUFA) and polyunsaturated fatty acids (PUFA) intake was associated with all-cause mortality (MUFA: 0.92, 0.86–0.98; PUFA: 0.91, 0.86–0.96). This meta-analysis supports that protein intake is associated with a decreased risk of CVD morbidity, while carbohydrate intake is associated with an increased risk of CVD morbidity. High total fat intake is associated with a low risk of all-cause mortality, and this effect was different in an analysis stratified by the type of fat. [ABSTRACT FROM AUTHOR]

Humans choose which foods they will eat from multiple options. The use of cafeteria-style diets with rodent models has increased our understanding of how a multichoice food environment affects eating and health. However, the wide variances in energy density, texture, and the content of micronutrients, fiber, and protein can be interpretatively problematic when human foodstuffs are used to create rodent cafeteria diets. We minimized these differences with a custom rodent cafeteria diet (ROD) that varied similarly to a previously used human-foods cafeteria diet (HUM) in fat and sugar content. Here, we used our custom Five-Item Food Choice Monitor to compare the intake and meal patterns of rats offered ROD and HUM in a crossover design. Compared with chow, rats consumed more calories, sugar, and fat and less protein and carbohydrate while on either of the choice diets (p < 0.05). While energy intake was similar between HUM and ROD, there were differences in the responses. Rats consumed more of the low-fat, low-sugar choice on the ROD compared with the nutritionally similar choice on the HUM leading to differences in fat and carbohydrate intake between the diets (p < 0.05). The stability of macronutrient intake while on either choice diet suggests macronutrient intake is determined by the available foods and is strongly regulated. Therefore, interpretative consideration must be given to the nature of food choices in the context of available options when interpreting cafeteria-diet intake. [ABSTRACT FROM AUTHOR]

Background and Objectives: Macronutrients play a vital role in liver dysfunction and affect tuberculosis treatment and prognosis. However, macronutrients intake was inadequate for most tuberculosis patients. This study aimed to clarify the associations between macronutrients intake or energy percentages and liver dysfunction in tuberculosis patients. Methods and Study Design: In this cross-sectional study, 2581 active tuberculosis patients aged =18 years were included from local tuberculosis clinics in Linyi, China. Macronutrients intake and energy percentages were assessed by 24-hour dietary recalls. The concentration of alanine transferase (ALT) or aspartate transaminase (AST) greater than 40 U/L was defined as liver dysfunction. A restricted cubic spline (RCS) was applied to determine the dose-response relationships. Results: Liver dysfunction was assessed for 14.6% (377 patients) of tuberculosis patients. Higher protein (Q2-Q4 in model 1 and 2) or fat intake and fat-to-energy percentages and lower carbohydrate-to-energy percentages (Q4 in model 1) were associated with a decreased incidence of liver dysfunction (p-trend < 0.05). Among those who were male, normal BMI, or consumed energy <1636 kcal/d, inverse associations between protein or fat intake and the risks of liver dysfunction in models were suggested (ptrend < 0.05). Moreover, J-shaped curves in RCS were evident in liver dysfunction tuberculosis patients with protein or fat intake (p-nonlinearity < 0.05). Conclusions: Significant linear associations between macronutrients intake or energy percentages and liver dysfunction prevalence were found only in male, normal BMI, or less energy intake patients. The shapes of liver dysfunction-morbidity differed significantly by macronutrients intake or energy percentage. [ABSTRACT FROM AUTHOR]

Diet quantity and quality in older adults is critical for the proper functioning of the musculoskeletal system. In view of hip surgery, old patients should consume 1.2–1.5 g of proteins and 27–30 kcal per kilo of body weight daily, and adhere to healthy eating habits. In this analytical study, we studied diet quantity and quality in relation to the clinical chemistry and functional status of 57 older adults undergoing elective hip replacement. Nine in ten patients did not meet suggested protein and energy intakes and only one in ten patients exhibited high adherence to the Mediterranean diet. Legume consumption adjusted for sex, age, body mass index, and health status successfully forecasted haemoglobin levels (p < 0.05), and patients regularly consuming olive oil reported minor hip disability compared to those using it less frequently (p < 0.05). Patients who reported daily ingestion of <1 serving of meat versus those consuming >1.5 servings had greater cumulative comorbidity (p < 0.05), with meat consumption independently predicting walking ability, mobility, and balance in the fully adjusted model (p < 0.01). In conclusion, our patients seem to eat poorly. There is room for improvement in pre-operative pathways to make older adults eat better, but there is a need to plan an interventional study to fully understand the cause–effect of a dietary pattern or specific food in enhancing recovery after surgery.

Background: A mother's nutritional knowledge, attitude, and children's macronutrient intake can affect the nutritional status of elementary school-age children. Objectives: This research analyzes the relationship between a mother's nutritional knowledge, attitude, children's macronutrient intake, and children's nutritional status at SDN Gedangrowo Prambon Sidoarjo. Methods: This research used a quantitative approach with a cross-sectional research design. It involved 110 students as research participants. The data were collected using multiple instruments. The research used the mother's nutritional knowledge test sheet to see the mother's nutritional knowledge knowledge. While an attitude questionnaire was distributed to investigate mothers' attitudes, the intake of macronutrients was measured using the Semi Quantitative Food Frequency Questionnaire (SQ-FFQ). These data were then analyzed using Logistic Regression Analysis. Results: The results showed that mothers' nutritional knowledge (p=0.002), attitude (p=0.002), children's energy intake (p=0.001), protein intake (p=0.000) and carbohydrate intake (p=0.008) had a relationship with children's nutritional status. Nevertheless, no relationship was found between fat intake (P=0,067) and children's nutritional status. The nutritional status of children is divided into undernutrition, good nutrition, and overnutrition. Conclusions: Mother nutritional knowledge, attitude, and children's energy, protein, and carbohydrate intake are related to children's nutritional status. There is no relationship between fat intake and children's nutritional status. Based on multivariate analysis, it is reported that protein intake has a strong relationship with children's nutritional status. [ABSTRACT FROM AUTHOR]

IntroductionMacronutrient intake can be one of the most influential factors in cognitive and neural development in adolescents. Adolescence is a specific period of cognitive and neural development, and nutritional effects during this period could be life-long. Therefore, understanding the effects of macronutrient intake on cognitive and neural development in adolescents is crucially important. We thus examined the association across macronutrient intake, intelligence, and neural development using population-based cohort data.MethodsWe conducted two studies. In study 1, we included a total of 1,734 participants (boys, 907, age [mean ± standard deviation] 171.9 ± 3.44 months; range 163.0–186.0 months) from the Tokyo TEEN Cohort (TTC) to examine the association between macronutrient intake and intelligence quotient (IQ). In study 2, we included a total of 63 participants (boys, 38, age 174.4 ± 7.7 months; range 160.7–191.6 months) to investigate the effect of nutrition intake on neural development using graph theory analysis for resting-state functional magnetic resonance imaging (rs-fMRI) derived from a subset of the TTC.ResultsTTC data revealed that a higher IQ was associated in boys with increased protein intake (β = 0.068, p = 0.031), and in girls, with reduced carbohydrate intake (β = −0.076, p = 0.024). Graph theory analysis for rs-fMRI at approximately age 12 has shown that impaired local efficiency in the left inferior frontal gyrus was associated with higher carbohydrate and fat intake ([x, y, z] = [−51, 23, 8], pFDR-corrected = 0.00018 and 0.02290, respectively), whereas increased betweenness centrality in the left middle temporal gyrus was associated with higher carbohydrate, fat, and protein intake ([x, y, z] = [−61, −43, −13], pFDR-corrected = 0.0027, 0.0029, and 0.00075, respectively). Moreover, we identified a significant moderating effect of fat and protein intake on the relationship between change in betweenness centrality over a 2-year measurement gap in the left middle temporal gyrus and intelligence (β = 12.41, p = 0.0457; β = 12.12, p = 0.0401, respectively).ConclusionOur study showed the association between macronutrient intake and neural development related to intelligence in early adolescents. Appropriate nutritional intake would be a key factor for healthy cognitive and neural development.

Background: It has been suggested that the quality of our sleep plays a significant role in developing Metabolic Syndrome (MetS). However, limited research is available on the association between sleep quality and MetS. Aim and Objectives: The objective of this study was to explore the prevalence of MetS and its relationship with nutritional status and sleep quality in the military forces. Material and Methods: A total of 190 people were surveyed using various questionnaires, including demographic, PSQI, DASS, and FFQ questionnaires. One-variable logistic regression, t-test, and Chi-square were used to analyze data. Results: The study included a total of 169 out of 190 individuals surveyed. The subjects' average age was 35.78 years, with a median sleep quality score of 6.61 (SD=3.0). No statistically significant relationship was found between MetS and biochemical components, macronutrient intake, and sleep quality. For every unit increase in protein and carbohydrate consumption, the likelihood of experiencing poor sleep quality increased by 2% and reduced by 1%, respectively (p

This study aimed to determine changes in energy and nutrient intakes over three consecutive days, including the day of the shift, and the days before and after the shift, in healthcare workers working in a 24 h shift system. This study is an observational follow-up study conducted with a total of 500 volunteer healthcare professionals. Food consumption records were taken over 3 consecutive days: pre-shift (off day), shift day (24 h shift), and post-shift (off day). Mean daily intakes of energy, carbohydrate, protein, fat, saturated fat, caffeine, vitamins B1, B2, niacin, B6, folate, and B12, potassium, magnesium, phosphorus, iron, and zinc are listed from highest to lowest as shift day > pre-shift > post-shift (p < 0.05 for all pairwise comparisons). While fiber, vitamin C, and calcium intakes were similar on the shift day and pre-shift day, they were significantly lower on the post-shift day (p < 0.05). The lowest dietary reference intake percentages on the post-shift day were calcium, fiber, and folate, respectively. In the present study, significant differences were detected in the energy, micronutrient-intake, and macronutrient-intake levels between the pre-shift day, shift day, and post-shift day of healthcare workers. Awareness should be increased regarding the decreased nutrient intake seen especially on the first day after a 24 h shift, and appropriate precautions should be taken to increase calcium, fiber, and folate intake levels.

Abstract Objective Evaluate the adequacy of energy/macronutrient intake in adolescents according to the Slovenian national recommendations adopted from the recommendations of the German Nutrition Society and to identify differences in energy/macronutrient intake between differently active adolescents. Methods Data on energy and macronutrient intake (24-hour dietary recall), physical activity (SHAPES questionnaire), and anthropometric characteristics (body mass and height) of adolescents were obtained on a representative sample of first-year secondary school students (average (SD) age: 15.3 (0.5) years; N = 341), who were included in the national survey The Analysis of Children’s Development in Slovenia (ACDSi) in 2013/14. Results 75% of adolescents met the national recommendations for carbohydrates and proteins and 44% for fats, whereas only 10% of adolescents met the recommendations for energy intake. Energy/macronutrient intakes were significantly higher in vigorously physically active (VPA) boys compared to moderately (MPA) and less (LPA) physically active boys. No such differences were observed between girls of different physical activity levels. Conclusion Adolescents need to be encouraged to meet their energy needs according to gender and physical activity (especially VPA girls) and to reach for higher quality foods in adequate macronutrient proportions.

AimMany studies have examined the relationship between chronotype and general health. Because healthy eating is the basis of health aim of this study is to evaluate the relationship between healthy nutrition attitudes and chronotype in young adults. Methods: This cross-sectional study was conducted with 1,400 young adults (936 females and 464 males). Chronotype was assessed by the Turkish version of the Morningness-Eveningness Questionnaire (MEQ) and the Attitude Scale for Healthy Nutrition (ASHN) was applied by face-to-face interview. Furthermore, 24-h dietary recall was collected. The scores of nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were calculated. The anthropometric measurements including body weight and height were taken.ResultsThe chronotype distribution of participants according to the MEQ score and MAR score were not significantly different between females and males (p > 0.05). The percentage of participants with high healthy eating attitude was lowest in the evening chronotype and highest in the morning chronotype (49.7, 37.7 and 25.4% in morning-, intermediate-, evening-types, respectively; p = 0.000 for all groups according to the reciprocal comparisons). There was a positive correlation of the MEQ scores with the scores of ASHN (r = 0.282, p

Abstract Background Nutritional intake plays an important role in determining energy availability which is vital to health, wellbeing, and sports performance in an active population. This research assessed the sports undergraduates' nutritional intake compared to the Dietary Guidelines for Americans and nutrition goals provided by WHO. Methods This study is a quantitative, cross-sectional descriptive study. One hundred and one (n = 101) sports undergraduates aged between 20 to 23 years were recruited and the nutrient intake was assessed using the three-day food diary method and quantified the macro and micronutrients by the food composition database. One sample t-test was performed to compare the mean nutrient intakes with the lowest recommendation values. Results Though most undergraduates were able to meet the dietary requirements in carbohydrates, they were deficient in their protein intake and exceeded in fats intake. Further, both male and female students were deficient in their daily energy intake (1723 kcal, 1607 kcal) and dietary fiber intake (8 g, 11 g). The saturated fat intake was met by all students while 20% of males and 21% of females exceeded the recommendations (

Although Volleyball is one of the most widely played sports in the World, there is little scientific information on how the ergo nutritional practice of female players should be designed. Therefore, the main aim of this narrative review is to resolute concise nutritional recommendations for volleyball women who players. Research databases such as PubMed, Scielo, Scopus, Medline or Academic Search Complete summarize and synthesize the recent evidence on the role of nutrition and its relationship with health and performance in this sporting discipline. Based on a literature review, we highlight that the individual adjustment of the energy value of the diet is one of the key factors for the physical performance of female volleyball players. An adequate intake of macronutrients allows for the achievement of correct energy values. To improve training adaptation, between 1.6 and 2.2 g·(kg·day)-1 of protein should be consumed. For optimal pre-competition muscle glycogen storage, 6-10 g·(kg·day)-1 of carbohydrates should be consumed, and 7- 10 g·(kg·day)-1 of carbohydrates should be consumed for adequate recovery. Micronutrients should be consumed in amounts corresponding to the recommended dietary allowances. Women volleyball players should take particular attention to the most adequate intake of these micronutrients, as well as vitamins such as iron, calcium, and vitamin D. Proper fluid intake, according to the player's needs, is crucial to maximize exercise performance. The diet of a female athlete is often characterized by low energy values, which increases the risk of various health consequences related to low energy availability. This diet of volleyball players must therefore be controlled carefully. [ABSTRACT FROM AUTHOR]

Evidence suggests that athletes competing in team sports do not follow dietary recommendations. However, only few studies have investigated energy needs and supplement use in adolescent athletes, and whether they are meeting their energy requirements. This observational study examined energy expenditure, dietary energy intake, and use of nutritional supplements in 58 adolescent (14–17 years old) volleyball athletes (15 males, 43 females) and 58 age-matched nonathletic controls (13 males, 45 females). Participants completed an online survey including questions on demographic information, body mass, and a series of standardized questionnaires assessing energy expenditure, dietary energy, macronutrient, micronutrient, and supplement intake. Energy expenditure relative to body mass was higher in athletes than nonathletes by 13 kcal/kg/day (group effect, p < 0.001), and in males compared to females by 5.7 kcal/kg/day (sex effect, p = 0.004). Athletes had higher energy intake than nonathletes (+6.4 kcal/kg/day, p = 0.019) and greater consumption of fruits (p = 0.034), vegetables (p = 0.047), grains (p = 0.016), dairy (p = 0.038), meats and meat alternatives (p < 0.001), as well as higher intakes of fat (p < 0.001), carbohydrates, protein, sugar, fiber, vitamin C, calcium, and sodium (p = 0.05) compared to nonathletes. The average protein intakes exceeded the upper recommendations in all groups, suggesting that this is not a nutrient of concern for young volleyball athletes. However, athletes were only meeting 60% of the estimated energy requirements (EER) for their age, height, body mass, and physical activity score, (3322 ± 520 kcal/day), while nonathletes were meeting 74% of the EER (p < 0.001). The relative energy balance of male athletes was lower compared to both female athletes (p = 0.006) and male nonathletes (p = 0.004). Finally, more athletes reported using performance-related supplements than nonathletes, but there were no differences in the consumption of other dietary supplements. Overall, when compared to nonathletic controls, both male and female adolescent volleyball athletes were found to match their higher energy expenditure with a greater dietary energy intake; however, all adolescents were below the estimated energy requirements, a finding more profound among the volleyball athletes.

Background: Learning from home is a government policy to decrease the number of COVID-19 in Indonesia. This condition requires university students to adapt to new technology that has the potential to affect sleep and consumption patterns that will influence their nutritional status. Objectives: The purpose of the study was to analyze the relationship between energy, macro-nutrient consumption, and sleep duration with the nutritional status of new students of FKM UNAIR. Methods: The research was an observational study with a cross-sectional design. A total of 55 students were randomly selected to be the research sample. Research data collection was done by using Google Forms. Research data were analyzed using the Spearman correlation test. Results: Most of the new FKM UNAIR students were female (87.3%), had sleep duration <7 hours/day (56.4%), and had normal nutritional status (69.1%). Most of the respondents had less intake of energy (47.3%), fat (54.5%), carbohydrates (60%), and excess protein intake (52.7%). The statistical tests showed that energy intake (p-value = 0.426), macronutrients including protein (p-value = 0.170), fat (p-value = 0.129), and carbohydrates (p-value = 0.884), also sleep duration (p-value = 0.190) was not related to the nutritional status of new students of FKM UNAIR. Conclusions: There was no correlation between energy intake, macronutrients, and sleep duration with the nutritional status of new FKM UNAIR students. Instead, students should pay attention to the duration of sleep and intake following the principles of balanced nutrition. [ABSTRACT FROM AUTHOR]

Many epidemiological studies have evaluated the intake of macronutrients and the risk of mortality and cardiovascular disease (CVD). However, current evidence is conflicting and warrants further investigation. Therefore, we carried out an umbrella review to examine and quantify the potential dose-response association of dietary macronutrient intake with CVD morbidity and mortality. Prospective cohort studies from PubMed, Embase, and CENTRAL were reviewed, which reported associations of macronutrients (protein, fat, and carbohydrate) with all-cause, CVD, cancer mortality, or CVD events. Multivariable relative risks (RR) were pooled, and heterogeneity was assessed. The results of 124 prospective cohort studies were included in the systematic review and 101 in the meta-analysis. During the follow-up period from 2.2 to 30 years, 506,086 deaths and 79,585 CVD events occurred among 5,107,821 participants. High total protein intake was associated with low CVD morbidity (RR 0.88, 95% confidence interval 0.82–0.94), while high total carbohydrate intake was associated with high CVD morbidity (1.08, 1.02–1.13). For fats, a high intake of total fat was associated with a decreased all-cause mortality risk (0.92, 0.85–0.99). Saturated fatty acid intake was only associated with cancer mortality (1.10, 1.06–1.14); Both monounsaturated fatty acid (MUFA) and polyunsaturated fatty acids (PUFA) intake was associated with all-cause mortality (MUFA: 0.92, 0.86–0.98; PUFA: 0.91, 0.86–0.96). This meta-analysis supports that protein intake is associated with a decreased risk of CVD morbidity, while carbohydrate intake is associated with an increased risk of CVD morbidity. High total fat intake is associated with a low risk of all-cause mortality, and this effect was different in an analysis stratified by the type of fat.

Humans choose which foods they will eat from multiple options. The use of cafeteria-style diets with rodent models has increased our understanding of how a multichoice food environment affects eating and health. However, the wide variances in energy density, texture, and the content of micronutrients, fiber, and protein can be interpretatively problematic when human foodstuffs are used to create rodent cafeteria diets. We minimized these differences with a custom rodent cafeteria diet (ROD) that varied similarly to a previously used human-foods cafeteria diet (HUM) in fat and sugar content. Here, we used our custom Five-Item Food Choice Monitor to compare the intake and meal patterns of rats offered ROD and HUM in a crossover design. Compared with chow, rats consumed more calories, sugar, and fat and less protein and carbohydrate while on either of the choice diets (p < 0.05). While energy intake was similar between HUM and ROD, there were differences in the responses. Rats consumed more of the low-fat, low-sugar choice on the ROD compared with the nutritionally similar choice on the HUM leading to differences in fat and carbohydrate intake between the diets (p < 0.05). The stability of macronutrient intake while on either choice diet suggests macronutrient intake is determined by the available foods and is strongly regulated. Therefore, interpretative consideration must be given to the nature of food choices in the context of available options when interpreting cafeteria-diet intake.

Malnutrition in children can contribute to growth limitations, and susceptibility to infection, which ultimately can inhibit the children’s growth and development. This study aimed to determine the fulfillment of macronutrient intake, micronutrient intake, and nutritional status of elementary school children at State Elementary School (hereafter SDN) Ammatoa Area, Kajang District, and Bulukumba Regency. This research was a descriptive study involving a population of 131 children and a sample of 65 children obtained by accidental sampling. The data were analyzed by using descriptive analysis of the percentage test. The results showed that the majority of macro-carbohydrate intakes (56.9%) were in the sufficient category, the majority of protein and fat (61.5% and 84.6%) were in the less category, while the intake of micronutrients, namely iron, zinc, and calcium primarily (83.1%, 80%, and 92.3%) in the less category, and the majority of nutritional status (86.2%) in the normal category. It was concluded that the intake of macro and micronutrients in elementary school children at the SDN Ammatoa region tended to be still lacking/low, despite their nutritional status, which tended to be normal. It is hoped that the relevant agencies will provide counselling to students regarding healthy and nutritious food by utilizing local food diversification in the Ammatoa customary area.

Simple Summary: This paper looks at changes in weight, physical activity, and food/dietary intake during the first year of the COVID-19 pandemic in undergraduate students enrolled in a Canadian university. The investigation used an online survey format to collect data at the end of the two lockdown periods over one year. Participants were recruited from universities across Canada. The results show a modest weight gain accompanied by a decrease in physical activity and an unhealthy change in diet. Specifically, students reported that their engagement in specific physical activities and overall activity levels decreased during the lockdowns. The number of calories also decreased over time, while the foods consumed decreased in nutritional value. Thus, the modest weight gain observed may have resulted from the decrease in physical activity and diet quality. In conclusion, Canadian food and physical activity recommendations were not met during the lockdowns caused by the pandemic, which highlights the physical and nutritional implications of confinement. This study examined changes in body mass and body mass index (BMI), physical activity, and dietary intake in Canadian university students during the first year of the COVID-19 pandemic. Two self-reported recall surveys were conducted: after the first lockdown in September 2020 (T1) and following the second lockdown in March 2021 (T2). Eligible participants were full-time undergraduate students attending a Canadian university and residing in Canada during the first year of the pandemic. At T1, 510 students (99 male, 411 female) completed the survey, and of those, 135 (32 males, 103 females) completed the survey at T2 (73% attrition). At both T1 and T2, most participants were 18–24 years of age (93% and 90%, respectively), Caucasian (73% and 78%, respectively), and resided in the province of Ontario (79% and 80%, respectively). Body mass increased from T1 to T2 (+0.91 ± 3.89 kg t(132) = −2.7, p = 0.008). BMI also increased from T1 to T2 (+0.30 ± 1.33 kg/m2 [t(130) = −2.5, p = 0.012), with a greater number of participants within the overweight range (19.8% versus 24.4%, respectively). At T1, 38% of the participants reported a decrease in physical activity, while the number of students reporting a decrease in activity increased to 56% at T2. Dietary energy intake decreased from 1678 ± 958 kcal/day at T1 to 1565 ± 842 kcal/day at T2 [c2(1) = 7.2, p = 0.007]. Diet quality also decreased, with participants not meeting the recommended daily allowance for essential macro and micronutrients. A decrease was observed in daily servings of fruits (−27%, p < 0.001), vegetables (−72%, p < 0.001), and grains (−68%, p < 0.001). In conclusion, despite a small decrease in dietary energy intake, a modest weight gain occurred during the first year of the COVID-19 pandemic in this cohort of Canadian university students, which was potentially related to decreased physical activity and diet quality.

Further, both male and female students were deficient in their daily energy intake (1723 kcal, 1607 kcal) and dietary fiber intake (8 g, 11 g). The saturated fat intake was met by all students while 20% of males and 21% of females exceeded the recommendations (< 10%). The micronutrient intake of vitamins such as C, B1, B2, B9, and B12 and minerals such as Calcium, Magnesium, and Potassium, were significantly below the recommendations (p < 0.05) except for vitamin B3 niacin. Conclusions: Providing a nutritionally valuable meal is essentially required to maintain both physical and mental fitness. Our results revealed that the Sri Lankan sport science undergraduates do not have an adequate daily dietary intake of energy, proteins, calcium, magnesium, potassium, and vitamins such as C, B1, B2, B9, and B12.

Adequate nutrition during childhood is vital for proper growth and development. However, nutrient intakes of Filipino school-age children are shown to be inadequate. This study assessed the nutrient intakes among school-age children from districts with the highest malnutrition rate in Davao City, Philippines. Using 3-day food records, dietary intake data were collected from a representative sample of 165 schoolchildren (aged 10-12 years) from six public schools in Poblacion, Paquibato, and Marilog districts. The nutrient intakes were calculated from the indicated food quantities, and the USDA food composition table was used as the primary database. These were compared with the 2015 Philippine Dietary Reference Intake values. Intake of total energy (102.56%), protein (165.11%), and some micronutrients reached the required amounts. On the other hand, inadequacies in several nutrients were identified: lipid intake was 49.01% of the recommended level, carbohydrate at 91.68%, dietary fiber at 53.16%, vitamin C at 54.98%, folate at 67.69%, vitamin E at 43.48%, vitamin D (IU) at 89.20%, calcium at 48.93%, and iron at 53.70%. Excess intakes of sodium (683.07%) and vitamin B12 (520.74%) were also reported. These findings suggest the need for targeted intervention programs that address nutrient inadequacies among Filipino school-age children. [ABSTRACT FROM AUTHOR]

NOVA classification distinguishes foods by level of processing, with evidence suggesting that a high intake of ultra-processed foods (UPFs, NOVA category 4) leads to obesity. The Australian Dietary Guidelines, in contrast, discourage excess consumption of "discretionary foods" (DFs), defined according to their composition. Here, we (i) compare the classification of Australian foods under the two systems, (ii) evaluate their performance in predicting energy intakes and body mass index (BMI) in free-living Australians, and (iii) relate these outcomes to the protein leverage hypothesis of obesity. Secondary analysis of the Australian National Nutrition and Physical Activity Survey was conducted. Non-protein energy intake increased by 2.1 MJ (p < 0.001) between lowest and highest tertiles of DF intake, which was significantly higher than UPF (0.6 MJ, p < 0.001). This demonstrates that, for Australia, the DF classification better distinguishes foods associated with high energy intakes than does the NOVA system. BMI was positively associated with both DFs (−1. 0, p = 0.0001) and UPFs (−1.1, p = 0.0001) consumption, with no difference in strength of association. For both classifications, macronutrient and energy intakes conformed closely to the predictions of protein leverage. We account for the similarities and differences in performance of the two systems in an analysis of Australian foods. [ABSTRACT FROM AUTHOR]

Summary: Background/Objectives: Few studies have assessed the independent and longitudinal effects of each macronutrient intake on adiposity throughout childhood. We aimed to prospectively assess the independent associations between each macronutrient intake at 4, 7, and 10 years (protein, carbohydrates, fat, and fibre) and each measure of adiposity from 7 to 10 years of age by sex. Methods: Data from the population‐based birth cohort Generation XXI was used (n = 3999). At 4, 7, and 10 years old, dietary, anthropometric and sociodemographic data were collected. The dietary intake of the children was evaluated by a validated food frequency questionnaire. Age‐ and sex‐specific body mass index z‐scores (zBMI), percentage of body fat (%FM) from bio‐impedance, and waist‐to‐hip ratio (Whr) were used as measures of adiposity. Path analysis tested the independent associations between each macronutrient intake (protein, carbohydrates, fat, and fibre) and each measure of adiposity from 7 to 10 years of age. Results: In fully adjusted models, an increase in energy from fibre intake at the age of 7 was associated with lower zBMI at the same age (β = −0.073; 95%CI [−0.127,‐0.019]) and at 10 years (β = −0.083; 95%CI [−0.137,‐0.029]). Similar results were found for %FM and Whr, and in each sex separately. At the age of 10, an increase in energy from fibre intake was associated with lower %FM and Whr, while an increase in energy from protein was associated with an increase in Whr (β = 0.061; 95%CI [0.014, 0.107]). Conclusions: Our study supports the protective effect of fibre intake on adiposity development during childhood in both sexes. [ABSTRACT FROM AUTHOR]

Selective pressures exerted on the feeding behaviour of animals have been extensively studied to understand their foraging patterns. In herbivores, specific within‐plant patterns of resource exploitation have been reported, but their determinants remain poorly understood.Here, we describe and decipher the determinants of the foraging pattern of the pollen beetle Brassicogethes aeneus, a pollinivorous insect that is a pest of oilseed rape Brassica napus. This insect feeds from flowers for almost all of its life cycle, except for a couple of weeks preceding blossoming. During this period, only flower buds are available and the insect destroys them to feed from the pollen they contain, causing serious yield losses.We found that during this critical period, pollen beetles exhibit a stereotypic intra‐inflorescence feeding pattern that depends on flower bud maturity. To explain this pattern, we first deciphered the selective pressures driving pollen beetles' feeding behaviour. Using a set of manipulative laboratory experiments, including behavioural experiments on plant tissues and artificial substrates, chemical characterization of plant tissues and performance experiments, we show that the pollen beetles' feeding behaviour does not seem to be driven by specialized metabolites or an attempt to reach an optimal nutrient balance, but rather by a process of maximization of total macronutrient intake. Next, using optimal diet choice models, we found that one aspect of the intra‐inflorescence feeding pattern, the preference for young over old flower buds, could be well‐explained through the lens of total macronutrient intake maximization per unit of time to access the resource.Our study provides new insights into small‐scale foraging patterns and highlights the need to characterize and assess the relative influence of several components of diet quality when deciphering selective pressures driving foraging patterns.

BackgroundAdolescence is a critical stage in the life cycle that presents a window of opportunity for the formation of lifetime habits or an aversion to childhood malnutrition effects. This study assessed the lifestyle habits, macronutrient intakes, and obesity prevalence among adolescents in some selected Senior High Schools in rural communities in Ho Municipality.Materials and methodsA cross-sectional survey was conducted among 272 adolescents aged 13–19 years and attending senior high schools in the Ho Municipality of Ghana. Data on sociodemographic, physical activity levels, dietary habits, and anthropometrics were obtained. A body mass index (BMI) and waist circumference (WC) were determined, while a repeated 24-h dietary recall was used to collect the dietary intakes of the participants.ResultsThe majority of the adolescents did not meet the Recommended Dietary Allowances (RDA) for calories (94.5%), dietary protein (68.8%), and fibre (91.5%). Adolescent boys consumed more calories (1,969.7 ± 579.9 Kcal) on average than adolescent girls (1,658.0 ± 458.7 Kcal) (p = 0.001). Overweight and obesity prevalence were 15.8 and 8.5%, respectively. About 90.4% of the adolescents did not meet the WHO recommended 150 min per week of physical exercise. On sedentary, 97.6% of adolescents spent half an hour to 5 h per day watching television when at home. Breakfast was the most frequently skipped meal (47.9%), and 59.6% of adolescents consumed fast foods such as pizza, burgers, and ice cream one to three times per week. Adolescent girls also had higher odds of being overweight or obese compared with adolescent boys (AOR = 2.4, p = 0.094, 95% CI = 0.9–6.4). Adolescents who did not meet the RDA for calories had lower odds of being overweight or obese compared with those who did (UOR = 0.3, p = 0.045, 95% CI = 0.1–0.9).ConclusionPoor dietary habits and intake, sedentary lifestyle, and obesity prevalence were observed among the adolescents. Being an adolescent girl was associated with obesity risk, while not meeting caloric intake showed a protective effect. Efficient and effective nutrition and lifestyle education programme should be promoted in communities to improve the dietary intake and lifestyle habits of adolescents.
