Abstract:
Objective:To analyze the status of hypertension and isolated systolic hypertension and to investigate the relationship between the prevalence of hypertension and dietary factors among Chinese elderly aged 60 yea and over during 2010-2012.
Methods:Using a multi-stage stratified probability proportional to size cluster randomization sampling method during 2010-2012, a total of 14 791 old people aged 60 years old and over were investigated at 150 counties (districts) from 31 provinces (autonomous regions and municipalities) in China. Information on demographic socio-economic status and the physical activities was collected through questionnaires. Blood pressure measurement and physical examination were carried out by standard methods. The 3 days consecutive individual 24 hours dietary investigation was used to calculate food and nutrients intake of the subjects. Multiple logistic regression was used to investigate the possible related dietary factors for the hypertension and isolated systolic hypertension.
Results:The prevalence of hypertension among the elderly aged 60 years old and over was 54.6% (95%CI: 52.8%-56.4%), of which isolated systolic hypertension was 24.5% (95%CI: 23.0%-26.1%). Compared with the lowest intake level, the OR (95%CI) of hypertension for higher tuber consumption (≥43.34 g/d) and milk intake (>0 g/d) with were 0.89 (0.83-0.97) and 0.88 (0.81-0.97), respectively. The OR (95%CI) of hypertension for higher dietary potassium (≥1 747.69 mg/d), folate acid (28.42-56.88 μg/d), vitamin B12 (0.22-0.58 μg/d) and vitamin B2 (0.61-0.81 mg/d) intake were 0.87 (0.77-0.98), 0.89 (0.81-0.98), 0.88 (0.80-0.97) and 0.89 (0.80-0.99). The OR (95%CI) of isolated systolic hypertension for higher tuber (≥43.34 g/d), milk intake (>0 g/d) and higher dietary potassium (≥1 747.69 mg/d), folate acid (≥99.89 μg/d), vitamin B12 intake (≥1.48 μg/d) were 0.84 (0.75-0.93), 0.85 (0.76-0.95), 0.82 (0.71-0.96), 0.87 (0.76-0.99) and 0.87 (0.77-0.98).
Conclusion:There was inverse association between highertuber consumptione, milk consumption, dietary potassium, folate acid, vitamin B12 intake and elderly hypertensive and isolated systolic hypertension.
