Key result
A 2-year substantial BMI gain increased the risk of incident hypertension in men (HR 1.81; 95% CI 1.22-2.68; P=0.002), while the risk in women was influenced by menopausal status.

Short-term BMI gain may raise hypertension risk in men; leaves open causal prevention effects pending randomized trials.

Does a short-term increase in BMI increase the risk of incident hypertension in adults?
Effect estimate: HR 1.81 (95% CI 1.22-2.68)
p-value: p=0.002
A substantial 2-year BMI gain is associated with a persistent risk for developing hypertension in men, while in women the risk is significantly influenced by menopausal status.
Chen et al. (2009) conducted a cohort in Free from hypertension, stroke, coronary heart disease, and diabetes (n=1,566). Highest quartile of BMI change vs. Lowest quartile of BMI change was evaluated on Incident hypertension (HR 1.81, 95% CI 1.22-2.68, p=0.002). A 2-year substantial BMI gain increased the risk of incident hypertension in men (HR 1.81; 95% CI 1.22-2.68; P=0.002), while the risk in women was influenced by menopausal status.
