Abstract
OBJECTIVES
We investigated the association of individual healthy lifestyle factors (HLFs) and their combined healthy lifestyle score (HLS) with hypertension and/or dyslipidemia.
METHODS
We analyzed data from 10,693 adults aged ≥19 from the 2019 to 2021 Korea National Health and Nutrition Examination Survey. HLS was evaluated based on smoking status, alcohol consumption, body mass index (BMI), diet, and physical activity. Using logistic regression models, we estimated odds ratios (ORs) with 95% confidence intervals (CIs) to evaluate the associations of HLFs and HLS with hypertension, dyslipidemia, and their comorbidity.
RESULTS
The prevalence of hypertension alone, dyslipidemia alone, and their comorbidity was 8.7%, 24.6%, and 15.0%, respectively. Multivariable models showed an inverse association of hypertension (OR, 0.37; 95% CI, 0.30 to 0.46) and dyslipidemia (OR, 0.36; 95% CI, 0.32 to 0.41) with healthy BMI. Hypertension was inversely associated with healthy alcohol consumption (OR, 0.46; 95% CI, 0.35 to 0.61) and diet (OR, 0.79; 95% CI, 0.63 to 0.99), whereas dyslipidemia was inversely associated with non-smoking (OR, 0.51; 95% CI, 0.43 to 0.60). Physical activity was inversely associated with their comorbidity (OR, 0.69; 95% CI, 0.56 to 0.85). Adherence to HLS was associated with significantly lower odds of hypertension (81%), dyslipidemia (66%), and their conditions (89%) (all ptrend<0.001). Stratified analyses consistently showed inverse associations between HLS and hypertension and/or dyslipidemia independently of demographic factors (pinteractions>0.05).
CONCLUSIONS
HLFs were associated with lower risk for hypertension and/or dyslipidemia. Obesity may contribute significantly to the risk of these conditions, while relevant HLFs for individual chronic diseases may vary significantly.
Summary
Korean summary
건강한 생활 습관 요인(HLFs)의 개별 구성 요인들은 고혈압 및 이상지질혈증의 동반 위험과 각각의 상태와 음의 연관성을 보였다. 다양한 HLFs 중에서 BMI 상태가 중요한 요인으로 확인되었지만, 개별 만성 질환에 대한 관련 HLFs는 상당히 다를 수 있다. 또한, 명확한 용량-반응 관계가 관찰되어, 더 HLFs를 준수할수록 고혈압, 이상지질혈증 및 그들의 동반 가능성이 유의미하게 감소하는 것으로 나타났다.
Key Message
Individual components of healthy lifestyle factors (HLFs) were inversely associated with the risk of comorbid hypertension and dyslipidemia, as well as with each condition. Among the various HLFs, BMI status was identified as a significant factor, while relevant HLFs for individual chronic diseases may vary significantly. Additionally, clear dose-response associations were observed, indicating that adherence to more HLFs was significantly associated with decreasing odds of hypertension, dyslipidemia, and their comorbidity.
