To investigate the association between blood pressure and all-cause mortality in Shanxi, China. The '2002 China Nutrition and Health Survey' baseline data in Shanxi province was used. A retrospective investigation was performed in 2015. The effects of SBP and DBP on the all-cause mortality were analyzed using the Cox regression model. The hazard ratio (HR) and 95% confidence interval (CI) were estimated by the sex and age groups. The follow-up rate was 76.52% over 13 years, while the cumulative mortality rate for all participants was 917.12/100,000 person-years. The mortality rose with an increasing SBP (χ2 trend = 270.537, P < 0.001) or DBP level (χ2 trend = 57.240, P < 0.001). After adjustment for the confounding factors, a significant association between mortality and high SBP (≥ 160 mmHg) and high DBP (≥ 100 mmHg), with adjusted HR ranging from 1.405- to 2.179-fold for SBP and 1.550- to 2.854-fold for DBP, was noted. Significant HRs for most DBP subgroups were found in > 60-year-old participants. Males with DBP ≥ 100 mmHg had a significantly higher mortality, with an HR (95% CI) of 2.715 (1.377–5.351). Adults with SBP > 160 mmHg and DBP > 100 mmHg had a higher mortality risk. Sex and age difference was noted in both DBP and mortality risk. [ABSTRACT FROM AUTHOR]

This study aimed to assess the association of waist circumference (WC) with all-cause mortality among Chinese adults. The baseline data were from Shanxi Province of 2002 China Nutrition and Health Survey. The death investigation and follow-up visit were conducted from December 2015 to March 2016. The visits covered up to 5,360 of 7,007 participants, representing a response rate of 76.5%. The Cox regression model and floating absolute risk were used to estimate hazard ratio and 95% floating CI of death by gender and age groups (≥ 60 and < 60 years old). Sensitivity analysis was performed by excluding current smokers; participants with stroke, hypertension, and diabetes; participants who accidentally died; and participants who died during the first 2 years of follow-up. This study followed 67,129 person-years for 12.5 years on average, including 615 deaths. The mortality density was 916 per 100,000 person-years. Low WC was associated with all-cause mortality among men. Multifactor-adjusted hazard ratios (HR) were 1.60 (1.35–1.90) for WC < 75.0 cm and 1.40 (1.11–1.76) for WC ranging from 75.0 cm to 79.9 cm. Low WC (< 70.0 cm and 70.0–74.9 cm) and high WC (≥ 95.0 cm) groups had a high risk of mortality among women. The adjusted HR s of death were 1.43 (1.11–1.83), 1.39 (1.05–1.84), and 1.91 (1.13–3.22). WC was an important predictor of death independent of body mass index (BMI). WC should be used as a simple rapid screening and predictive indicator of the risk of death. [ABSTRACT FROM AUTHOR]

Obesity is recognized as a significant risk factor for diabetes and hypertension. The present study aimed to examine the associations between adults' obesity risk and childhood and parental obesity. A total of 204 children aged 6-17 years were recruited in 2002 with an average follow-up period of 13.2 years. Height and body weight were measured by trained staffs. Overweight and obesity were defined based on the Chinese standard for children and adults. T-test, analysis of variance, and Chi-square analysis were used for single factor analysis. Multiple linear and logistic regression analyses were used to perform multifactor analysis. The percentage of non-obese children who grew up to be non-obese adults was 62.6%, and that of obese children who grew up to be obese adults was 80.0%. There was a significant association between childhood body mass index (BMI) and adulthood BMI with a β regression coefficient of 3.76 [95% confidence interval (CI): 1.36-6.16], and between childhood obesity and adulthood obesity with an odds ratio of 5.76 (95% CI : 1.37-24.34). There was no statistical difference between parental obesity at baseline and children's adulthood obesity, after adjustment of confounders. Male participants and those aged 10.0-13.0 years had a higher risk of adulthood obesity with odds ratios of 2.50 (95% CI : 1.12-5.26) and 3.62 (95% CI : 1.17-11.24), respectively. Childhood obesity is an important predictor of adulthood obesity. [ABSTRACT FROM AUTHOR]
