Association between dietary patterns and depressive symptoms among middle-aged adults in China in 2016-2017.

The purpose of this study was to explore the associations of dietary patterns with depressive symptoms in middle-aged Chinese adults. The cross-sectional study participants were 1360 Chinese adults (45-59 years, 659 males and 701 females) who participated in a Health Survey at the time of periodic checkup. Dietary intakes were assessed via a semi-quantitative food frequency questionnaire (FFQ). Binary logistic regression analysis was used to estimate odds ratio(OR) and 95% confidence interval(CI) for depressive symptoms according to quartiles of each dietary pattern score. Four major dietary patterns were identified by factor analysis: traditional Chinese, Western, grains-vegetables and high-salt patterns. After controlling for potential confounders, participants in the highest quartile of the Western pattern scores had greater odds of depressive symptoms than those in the lowest quartile. In contrast, participants in the highest quartile of the grains-vegetables pattern had lower odds of depressive symptoms than those in the lowest quartile. Nevertheless, no significant associations were observed between the traditional Chinese and high-salt patterns and the risk of depressive symptoms, even after adjusting for potential confounders. The findings indicate that the Western pattern is associated with an increased risk, and the grains-vegetables pattern is associated with a reduced risk of depressive symptoms.

Empirically Derived Dietary Patterns and Hypertension Likelihood: A Meta-Analysis.

BACKGROUND/AIMS: Dietary patterns, which represent whole-diet and a complex integration of food and nutrient, have been reported to play an important role in the development of hypertension. However, the results have yielded conflicting findings. Herein, we performed this meta-analysis to evaluate the associations between different dietary patterns and the likelihood of hypertension. METHODS: MEDLINE and EBSCO were searched to identify relevant articles published until the end of March 2016. A random-effects model was used to account for possible heterogeneity between studies.A total of twenty-seven studies met the inclusion criteria and were included in this meta-analysis. RESULTS: There was evidence of a decreased likelihood for hypertension in the highest compared with the lowest categories of healthy pattern (odds ratio (OR)=0.81; 95% confidence interval(CI): 0.67-0.97; P=0.02). An increased likelihood of hypertension was shown for the highest compared with the lowest category of heavy drinking pattern (OR=1.62; 95% CI: 1.16-2.26; P=0.004), whereas no statistically significant association with western-style and light-moderate drinking pattern were observed(OR=1.04, 95% CI: 0.83-1.31; OR=1.20, 95% CI:0.94- 1.53; P>0.05). CONCLUSIONS: Our results of this systematic review and meta-analysis suggest that dietary pattern may be associated with the likelihood of hypertension.
