A family history of hypertension significantly increased the odds of having hypertension (OR 1.29) compared to no family history among Sri Lankan adults.

Does a family history of hypertension increase the prevalence of hypertension and metabolic risk factors in Sri Lankan adults?
A family history of hypertension is significantly associated with an increased prevalence of hypertension, obesity, and metabolic syndrome in Sri Lankan adults, identifying a group that may benefit from targeted interventions.
Odds Ratio: 1.29 (95% CI 1.13–1.47)
Absolute Event Rate: 29.3% vs 24.4%
p-value: p=<0.001
BACKGROUND: Hypertension is a major contributor to the global non-communicable disease burden. Family history is an important non-modifiable risk factor for hypertension. The present study aims to describe the influence of family history (FH) on hypertension prevalence and associated metabolic risk factors in a large cohort of South Asian adults, from a nationally representative sample from Sri Lanka. METHODS: A cross-sectional survey among 5,000 Sri Lankan adults, evaluating FH at the levels of parents, grandparents, siblings and children. A binary logistic regression analysis was performed in all patients with 'presence of hypertension' as dichotomous dependent variable and using family history in parents, grandparents, siblings and children as binary independent variables. The adjusted odds ratio controlling for confounders (age, gender, body mass index, diabetes, hyperlipidemia and physical activity) are presented below. RESULTS: In all adults the prevalence of hypertension was significantly higher in patients with a FH (29.3%, n = 572/1951) than those without (24.4%, n = 616/2530) (p < 0.001). Presence of a FH significantly increased the risk of hypertension (OR:1.29; 95% CI:1.13-1.47), obesity (OR:1.36; 95% CI: 1.27-1.45), central obesity (OR:1.30; 95% CI 1.22-1.40) and metabolic syndrome (OR:1.19; 95% CI: 1.08-1.30). In all adults presence of family history in parents (OR:1.28; 95% CI: 1.12-1.48), grandparents (OR:1.34; 95% CI: 1.20-1.50) and siblings (OR:1.27; 95% CI: 1.21-1.33) all were associated with significantly increased risk of developing hypertension. CONCLUSIONS: Our results show that the prevalence of hypertension was significantly higher in those with a FH of hypertension. FH of hypertension was also associated with the prevalence of obesity, central obesity and metabolic syndrome. Individuals with a FH of hypertension form an easily identifiable group who may benefit from targeted interventions.
Ranasinghe et al. (Fri,) conducted a cross-sectional in Hypertension (n=4,482). Family history of hypertension vs. No family history of hypertension was evaluated on Prevalence of hypertension (OR 1.29, 95% CI 1.13-1.47, p=<0.001). A family history of hypertension significantly increased the odds of having hypertension (OR 1.29) compared to no family history among Sri Lankan adults.
