What factors are associated with control of blood pressure among elderly people diagnosed with hypertension?
In elderly Korean patients with hypertension, blood pressure control is poor (25.9%) and is strongly associated with general obesity in men and abdominal obesity in women.

May warrant sex-specific obesity screening in elderly hypertension; leaves open causality and intervention effects.
OBJECTIVE: Control of blood pressure is important in old age for prevention of hypertension-associated complications. This study aimed to investigate the factors associated with control of hypertension in elderly people (>or=60 years old) diagnosed with hypertension. METHODS: The subjects were those who had a self-reported diagnosis of hypertension (532 men and 1078 women) from a stratified random cluster sample of 4201 people aged 60 years or older. Controlled hypertension was defined as a systolic blood pressure (SBP) <140 mmHg and diastolic blood pressure (DBP) <90 mmHg, and SBP <130 mmHg and DBP <80 mmHg for subjects with diabetes. RESULTS: The prevalence of controlled hypertension (25.9%) was low. In older women, the prevalence of isolated uncontrolled SBP was increased. After adjusting for other covariates, uncontrolled hypertension was positively associated with body mass index (BMI>or=23 kg/m(2)), and negatively associated with balanced diet and a past history of cardiovascular disease in men, whereas in women it was positively associated with waist circumference (>or=80 cm). CONCLUSIONS: In elderly people diagnosed with hypertension general obesity (high BMI) appears to have an important influence on uncontrolled hypertension in men, whereas abdominal obesity (high waist circumference) appears to be an important factor in women.

Lee et al. (2009) conducted a cohort in Hypertension (n=1,610). General obesity (high BMI) and abdominal obesity (high waist circumference) vs. Normal BMI and waist circumference was evaluated on Controlled hypertension (SBP <140 mmHg and DBP <90 mmHg, or <130/80 mmHg for diabetes). General obesity in men and abdominal obesity in women were positively associated with uncontrolled hypertension among elderly patients, who had an overall controlled hypertension prevalence of 25.9%.
