Key result
Midday napping for 60 to 90 minutes was associated with an increased risk of hypertension among Chinese adults older than 45 years, with BMI acting as a partial mediator.
Why the study?
Hypertension is a major global public health issue and midday napping is a popular habit, but the association between the two remains to be explored.
Does midday napping increase the risk of hypertension in Chinese adults older than 45 years?
Cross-Sectional (n=33,592)
Yes
Does midday napping increase the risk of hypertension in Chinese adults older than 45 years?
Midday napping is positively associated with hypertension in Chinese adults over 45, with BMI acting as a partial mediator.
Answers are grounded in this paper and cite their sources.
Longer midday napping should not yet alter hypertension advice; leaves open causal confirmation in prospective studies of older Chinese adults.
Background Hypertension is one of the main public health issues around worldwide, and midday napping is a popular habit. The association between the two remains to be explored. Objective The goal of the research was to explore the association of midday napping with hypertension. Methods This study separately selected 11,439, 12,689, and 9464 Chinese respondents aged over 45 years from the China Health and Retirement Longitudinal Study 2011, 2015, and 2018 data sets. Binary logistic regression was used to explore the association of midday napping with hypertension, and the 3-step method was used to test the mediation effect of BMI. Results Among all respondents, the prevalence rates of hypertension were 24.6% (2818/11439) in 2011, 21.1% (2683/12689) in 2015, and 22.1% (2092/9464) in 2018. Midday napping was positively correlated with hypertension. In 2011 and 2015, napping 60 to 90 minutes had the greatest odds ratios [OR] (OR2011 1.705, OR2015 1.494). In 2018, the biggest OR came from the group napping 30 to 60 minutes (OR 1.223), and ORs of different napping durations decreased from 2011 to 2018. In addition, BMI had a partial mediation effect in 2015 and 2018. Conclusions Midday napping is a potential risk factor for hypertension with BMI acting as a mediator. To prevent hypertension, avoiding prolonged duration of midday napping and taking action to maintain a normal BMI level are recommended.

Tang et al. (2022) conducted a cross-sectional in Hypertension (n=33,592). Midday napping vs. No napping was evaluated on Hypertension (OR 1.705, 95% CI 1.346-2.159, p=<0.001). Midday napping for 60 to 90 minutes was associated with an increased risk of hypertension among Chinese adults older than 45 years, with BMI acting as a partial mediator.
