RESUMEN

Objective To explore the associations of body mass index (BMI), waist circumference (WC), waist height ratio (WHtR) and the prevalence of hypertension in elderly residents over 60 years in Baodi district, Tianjin. Methods Residents over 60 who underwent medical examinations in the Koudong Health Center, Baodi district, Tianjin, were all invited to participate in the study from April to May, 2018. Participants were asked to fill out structured questionnaires and undergo physical examinations. Stratified analysis and logistic regression analysis were applied to examine joint effects and interactions of BMI and WC (or WHtR) on the risk of hypertension. Results A total of 1 417 residents (83.75%) out of 1 692 residents participated in the study. The prevalence of hypertension in the participants was 46.36%. 66.50% of the participants were BMI overweight or obese. Participants with central obesity accounted for 74.66% (measured by the WC) and 75.38% (by the WHtR). Compared to the normal weight measured by the BMI or the WC, BMI overweight (OR=1.65, 95%CI: 1.19-2.30) or obesity (OR=3.41, 95%CI: 2.23-5.20) and WC central obesity (OR: 1.49, 95%CI: 1.00-2.23) were associated with increased risk of hypertension. The joint effects of BMI and WC (OR=2.49, 95%CI: 1.78-3.46), or BMI and WHtR (WHtR overweight: OR=2.05, 95%CI: 1.41-2.99; WHtR obesity: OR=2.37, 95%CI: 1.50-3.76) were greater than the single effect of the latter (WC overweight/obesity: OR=1.39, 95%CI: 0.90-2.15; WHtR overweight: OR=1.02, 95%CI: 0.62-1.66; WHtR obesity: OR=1.44, 95%CI:0.55-3.81). Conclusions Of the three indices, BMI is strongly correlated with the risk of hypertension. BMI overweight or obesity has enhanced the association of WC or WHtR and the risk of hypertension, suggesting that weight control in the normal range, especially measured by the BMI index, may prevent and control hypertension.

RESUMEN

Objective The aim of this study was to systematically evaluate the health status of Asian immigrants in Canada and the associated factors. Methods Using data from the 2003 Canadian Community Health Survey, a descriptive analysis was performed to estimate the frequency of health associated factors among different populations. Age-standardization rates was also used to compare the prevalence of chronic conditions among Asian immigrants, other immigrants and native residents. Logistic regression analysis was used to estimate the adjusted Odds ratio (0R) associated with each health outcome and 95% confidence interval (95%CI) after controlling for potential confounding factors. Results After age-standardization, Asian immigrants had a similar prevalence of 1-5 chronic conditions and a lower prevalence of 5+ chronic conditions (3.56%) compared with non-immigrants (5.31%). Asian immigrants were less likely to report any chronic disease (0R=0.49, 95% CI: 0.46-0.51) than non- immigrants (0R=1.00). Recent Asian immigrants were less likely to report any chronic condition (0R=0.34, 95% CI: 0.31-0.37) than long-term Asian immigrants (0R=0.62, 95% VI: 0.58-0.66). After adjusting for socioeconomic status and lifestyle factors, Asian immigrants had a slightly changed risk of four chronic conditions with exception of heart disease. Conclusion Asian immigrants had lower risk of chronic conditions as a whole, however, these health advantages decreased along with increasing length of residence in Canada. Socioeconomic factors and lifestyles cannot fully explain the differences of health status between Asian immigrants and non-immigrant Canadians reported in this paper.
