Sex-related association of modifiable risk factors with hypertension: A national cross-sectional study of NHANES 2007-2018.

Abstract

Sex difference is commonly observed in hypertension. We aimed to assess sex differences in the associations of modifiable lifestyle and metabolic risk factors with risk of hypertension. National cross-sectional population study. Data from the 2007 to 2018 National Health and Nutrition Examination Survey. 7087 adults aged ≥30 years without a prior history of hypertension. Odds ratios and population attributable fraction (PAF) of hypertension associated with 10 modifiable risk factors: five lifestyle risk factors (current smoking, excess alcohol intake, poor diet, physical inactivity, and unhealthy sleep), and five metabolic risk factors (obesity, diabetes, dyslipidaemia, hyperuricemia, and chronic kidney disease) in women versus men. Compared with women, men had 84% increased risk of prevalence of hypertension. The sex difference in risk for hypertension is more evident in those aged <60 years (p for interaction <.001). For those aged <60 years the combination of lifestyle risk factors accounted for a PAF of 27.2% in men and 48.8% in women, and the combination of metabolic risk factors accounted for a PAF similarly in men (37.4%) and women (38.2%). For those aged ≥60 years, the PAF of lifestyle risk factors was similar between men and women and the metabolic risk factors accounted for a greater proportion in women (33.0% vs. 14.5% in men). Sex differences may exist in the relation and attribution of lifestyle and metabolic risk factors to hypertension, which may have implications for implementing sex-specific strategies to prevent hypertension.
