What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Hypertension (n=33592). Intervention: Midday napping vs. No napping. Primary outcome: Hypertension (OR 1.705, 95% CI 1.346-2.159, p=<0.001).

What does this research mean for the field?

Midday napping, particularly for 60 to 90 minutes, is significantly associated with an increased risk of hypertension among older Chinese adults, with body mass index (BMI) acting as a partial mediator. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

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?

Population

11,439 (2011), 12,689 (2015), and 9464 (2018) Chinese respondents aged over 45 years

Comparison

Midday napping durations and their association with hypertension

Design

Cross-sectional study

Key result

Midday napping for 60 to 90 minutes was significantly associated with an increased risk of hypertension (OR 1.705) among Chinese adults older than 45 years, with BMI acting as a partial mediator.

Discussion

Member takes

Overview

Longer midday napping should not yet alter hypertension advice; leaves open causal confirmation in prospective studies of older Chinese adults.

Study Design

Type

Cross-Sectional (n=33,592)

Multicenter

Structured PICO

Does midday napping increase the risk of hypertension in Chinese adults older than 45 years?

Population

Chinese respondents aged over 45 years from the China Health and Retirement Longitudinal Study 2011 (n=11,439), 2015 (n=12,689), and 2018 (n=9,464) data sets.

Intervention

Midday napping (durations including 30 to 60 minutes and 60 to 90 minutes)

Comparator

No midday napping or different napping durations

Outcome

Prevalence of hypertension

Main Result

Effect estimate: OR 1.705 (95% CI 1.346-2.159)

p-value: p=<0.001

Midday napping is positively associated with hypertension in Chinese adults over 45, with BMI acting as a partial mediator.

Limitations

Cross-sectional study design limits causal inference
Self-reported midday napping duration may introduce recall bias
Potential residual covariates due to absence of genetic, family history, biomarker, and environmental data
Time-dependent covariates were not included, making comparisons across years difficult
Uncertain applicability to age groups younger than 45 years
Potential interaction effect of midday napping and night sleep was not analyzed

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 significantly associated with an increased risk of hypertension (OR 1.705) among Chinese adults older than 45 years, with BMI acting as a partial mediator.
