Blood Pressure, Serum Cholesterol Concentration and Their Related Factors in Urban and Rural Elderly of Ho Chi Minh City.

Abstract

SummaryIn Vietnam, information about blood pressure, serum lipids and their factors is limited. To obtain some of this information, a cross sectional nutrition survey was carried out in an urban and rural area of Ho Chi Minh City with 217 participants aged 60-69y (148 females and 69 males). Anthropometry and blood pressure were measured. For three consecutive weekdays, 24h dietary recalls were performed. Single 24h urine was collected for sodium and potassium analysis. A fasting blood sample was taken and biochemical pa rameters were measured. Results indicate a high percentage of hypertension in urban (fe male: 35.5%, male: 43.8%) and rural areas (female: 22.2%, male: 35.1%). Blood pressure was correlated with body mass index (BMI) and 24h urinary sodium-to-potassium (Na/K) ratio. A high prevalence of serum total cholesterol (TC) above 220mg/dL (female: 55.3%, male: 31.3%) and overweight (female: 34.2%, male: 25.0%) were observed in urban resi dents. By contrast, 5.6% and 24.3% of rural females and males respectively had TC below 150mg/dL and both genders had the same prevalence of underweight (32.4%). TC was positively correlated with body weight, BMI, dietary protein and dietary lipids. Overweight might be a major risk factor for hypertension in our urban elderly. A high Na/K intake ratio might be a risk factor for hypertension in both areas. The high prevalence of elevated TC in the urban area might to be related to the high lipid intake, and the high prevalence of low TC in the rural area might to be related to the low lipid intake.

Prevalence, Awareness, Treatment, Control and Risk Factors of Hypertension in the Guangxi Hei Yi Zhuang and Han Populations

“…In our current study, the percentage of subjects with a BMI > 24 kg/m 2 was only 10.9% in Hei Yi Zhuang and 20.6% in Han, suggesting that the effect of BMI on blood pressure was small in both nationalities. However, in the present study we found that the prevalence of hypertension was positively correlated with TG in Hei Yi Zhuang, and positively correlated with TC in Han (23).…”

Effects of Demographic Characteristics, Health-Related Behaviors and Lifestyle Factors on the Prevalence of Hypertension for the Middle-Aged and Elderly in the Guangxi Hei Yi Zhuang and Han Populations

“…In our current study, only 10.2% of the Hei Yi Zhuang and 22.7% of the Han subjects had a BMI 1 24 kg/m 2 , suggesting that the effect of BMI on the prevalence of hypertension is weak in both ethnic groups. However, the present study shows that the prevalence of hypertension was positively correlated with TGs in Hei Yi Zhuang and with TC in Han [51] . The relationship between hypertension and hyperlipidemia remains relatively poorly understood.…”

Insulin Resistance, Cognitive Impairment and Neurodegeneration: Roles of Nitrosamine Exposure, Diet and Lifestyles

“…Moreover, diets high in trans fatty acids, which are abundantly present in processed foods, caused abdominal obesity and insulin resistance (Kavanagh, Jones et al 2007). Similar effects of nutrient poor, calorically dense diets have been demonstrated in humans (Hodge, Dowse et al 1995;Tran, Komatsu et al 2001;Hursting, Lavigne et al 2003;Newby, Muller et al 2003). In humans, caloric restriction also retards aging and reduces rates of chronic disease; therefore, this simple measure may also help to reduce risk for neurodegeneration (Qin, Chachich et al 2006;Kim, Nguyen et al 2007;Wang, Fivecoat et al 2010).…”
