Interpretation of the Standards of Basic Dataset of Chronic Diseases Behavior Risk Factor Surveillance in Adults

BACKGROUND China’s Behavioral Risk Factor Surveillance System(BRFSS)originated from the World Bankfunded HealthⅦLoan Project in the 1990s,which conducted behavioral risk factor surveillance in seven cities and one province^([1]).Drawing on the World Health Organization’s(WHO)STEPwise approach to surveillance(STEPs)and the U.S.Behavioral Risk Factor Surveillance System(BRFSS)^([2,3]).

Childhood BMI and Adult Obesity in a Chinese Sample:A 13-Year Follow-up Study

Objective 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. Methods 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. Results 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. Conclusion Childhood obesity is an important predictor of adulthood obesity.

Abdominal Obesity and Its Attribution to All-cause Mortality in the General Population with 14 Years Follow-up:Findings from Shanxi Cohort in China

Objective This study aimed to assess the association of waist circumference(WC)with all-cause mortality among Chinese adults.Methods 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.Results 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 HRs of death were 1.43(1.11–1.83),1.39(1.05–1.84),and 1.91(1.13–3.22).Conclusion 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.

Association between Baseline SBP/DBP and All-Cause Mortality in Residents of Shanxi,China:A Population-based Cohort Study from 2002 to 2015

Objective To investigate the association between blood pressure and all-cause mortality in Shanxi,China.Methods 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.Results 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(χ_(trend)^(2)=270.537,P<0.001)or DBP level(χ_(trend)^(2)=57.240,P<0.001).After adjustment for the confounding factors,a significant association between mortality and high SBP(≥160 mm Hg)and high DBP(≥100 mm Hg),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 mm Hg had a significantly higher mortality,with an HR(95%CI)of 2.715(1.377–5.351).Conclusion Adults with SBP>160 mm Hg and DBP>100 mm Hg had a higher mortality risk.Sex and age difference was noted in both DBP and mortality risk.
