Body size and adiposity indicators and their relationship with blood pressure levels in Ibos of Nigeria.

BACKGROUND: Racial Predisposition to Hypertension, obesity and other cardiovascular diseases (CVD) have been the subject of some recent researches. The various anthropometric and obesity indicators and their relationship with blood pressure parameters in the Ibos of Nigeria were studied. METHOD: Using the simple random design, 569 males and females Nigerians of Ibo ethnicity, ages 20 to 80 years were enrolled for this study. Systolic and diastolic blood pressure (SBP & DBP), body mass index (BMI), waist hip ratio (WHR), waist height ratio (WHTR), waist circumference (We), triceps, subscapular, calf and sum of three skin fold thicknesses (TSF, SSF, eSF,& STS respectively) and other anthropometric parameters were measured. RESULT: The mean SBP for the study was 119.6 +/- 23 mmHg and DBP 79.8 +/- 13mmhg. Males showed higher mean values of 5mmHg in SBP and 3mmHg in DBP than the females. we was 3cm larger in the females than the males. BMI, WHTR, and STS were all larger in the females than in the males. The highest level of association noted in the study was between we and WHTR (r = 0.926, P < 0.01). The levels of correlations of the blood pressure parameters with the obesity indices were higher with DBP than SBP. For both sexes; we was the highest predictor of DBP, followed by WHTR. Age gave the highest prediction of SBP. CONCLUSION: This work notes WHTR as the best predictor of central obesity and also a better index for screening CVD risk factors in the Ibos.

Impact of urbanization on obesity, anthropometric profile and blood pressure in the Igbos of Nigeria.

BACKGROUND: Hypertension in developing setting is often attributed to westernization of life style and stresses of urbanization, some of these increases have been noted in Nigeria. AIM: This is a study on rural-urban differences on the blood pressure, obesity and anthropometrics among a major ethnic group in Nigeria. PATIENTS AND METHOD: A total of 325 men and 242 women aged 20 to 80 years, of the Igbo ethnicity were selected for this study. The samples were selected from the rural and urban subgroups of the Igbo population. Systolic and diastolic blood pressure, body mass index, waist- hip ratio, waist-height ratio, waist circumference, triceps, subscapular, calf and sum of the three skin fold thicknesses and other anthropometric measurements were obtained using standard procedures. RESULT: Blood pressure correlated with age and most of the anthropometric parameters (p< 0.05 ). All adiposity and blood pressure indicators were higher in the urban than in the rural sample. Women showed higher predisposition to both general and abdominal obesities in both samples. High blood pressure occurred more often in the urban sample than the rural. Urban men had the highest mean blood pressure (p< 0.05). High blood pressure appeared much connected with the pressures of city life. Regression formulae were derived for all the adiposity measures of Igbos in both rural and urban locations. CONCLUSION: High rates of obesity and hypertension are noted among Igbos in both rural and urban areas. This is especially in the urban setting. The finding is indicative of a low level of attention on hypertension and obesity in the Igbos. The data reported here call for intervention programs on the risks, preventions and management of obesity and obesity related conditions.

Impact of education on obesity and blood pressure in developing countries: A study on the Ibos of Nigeria.

BACKGROUND: Increase in the prevalence of hypertension, obesity and obesity related diseases has become significant cause of disability and premature death in both developing and newly developed countries, with over bearing demand on national health budgets. AIM: To evaluate the impact of various levels of education on obesity and blood pressure. MATERIALS AND METHOD: 325 male and 254 female Nigerians of ages 20-80 years of the Ibo ethnicity through random sampling, were selected for this study. The participants were broken into three major groups based on their educational levels; primary, secondary and tertiary levels. systolic and diastolic blood pressure (SBP & DBP) levels, body mass index (BMI), waist hip ratio (WHR), waist height ratio (WHtR), waist circumference (WC),various skin fold thicknesses, and other anthropometric parameters were measured. RESULT: For all the indicators of subcutaneous fat, general obesity, and central obesity, largest mean deposition was noted to be highest in the lowest education group and least in the highest education group. Mean blood pressure parameters were also highest in the least education group. While fat deposition was noted to be highest in all the females of all the groups, the males showed larger mean BP values. Education was noted to have a significant inverse relationship with most of the fat indicators and blood pressure parameters and cardiovascular disease risk highest in the least education groups. CONCLUSION: Education showed a significant impact on obesity and blood pressure and could be one of the major tools to reduce the high prevalence of obesity, hypertension and other obesity associated diseases.
