several factors have been associated with this trend range from changes in the physical , social and economic way of life and environments of the people , to genetic and physiologic factors .
education is one of the media that influences greatly the attitude , social , economic and physiologic behaviors of the people .
many studies have established relationship between education and socioeconomic status ( ses)[46 ] . while education can be seen to influence both ses and obesity , a number of works has been done on the relationship of obesity and ses , but the same can not be said for obesity and education .
part of the growing concern in the increasing rate of obesity and overweight is the varying rates at which they are distributed across social groups , by levels of education , ses and ethnic background .
lipowics commented on the increase in the association between obesity and higher social class among men , women and children in developing countries , but noted a strong inverse relationship between obesity and social class only among women in developed countries . while sobal and stunkard noted inconsistent and general non - linear direction in the relationship of obesity and ses in men and children , they noted consistent relationship with women , where obesity was more prevalent in women of low ses , than those of upper ses . in view of the present increase in the prevalence of obesity in developing countries and accelerated increase in blood pressure ( bp ) amongst black population adopting western lifestyle .
this work has been designed to determine the impact of education on obesity and bp in the ibo ethnic group of nigeria .
this was based on a random sampling of 567 subjects aged 20 to 80 years of the ibo ethnic group of nigeria .
this is of the three major ethnic groups ( ibos , hausa and yoruba ) in nigeria having a population density of over 800- 1500 per square kilometer .
after focused grouped discussions on the objective of the study , and with the consent of the participants , questionnaires were distributed to them and bp and anthropometric measurements were taken .
pregnant women and hypertensive patients and individuals with structural deformities were excluded from the measurement .
the first group called the primary education level consisted of candidates who had no form of formal education at all and also candidates who did not go beyond the first 6years of formal primary education .
the second group called the secondary education level included candidates that did not go beyond the secondary or college education .
the third group , tertiary education level , included candidates that have gone beyond the secondary education to tertiary education .
participants were allowed to rest at least for 10minutes in a seated position with arms supported at the level of the heart .
the bp was measured three times with the cuff completely evacuated and recovery allowed between readings .
the average of the readings was used as the systolic ( sbp ) and diastolic blood pressures ( dbp ) .
height ( ht ) was measured to the nearest 0.5 cm using a vertical scale of portable stadiometer with the participant in erect position without shoes and head held in the frank fort plane .
weight was measured to the nearest 0.1 kg with a bathroom scale with the participant lightly clothed .
bmi was calculated as weight divided by square of height ( kg / m2 ) .
hip circumference ( hc ) was measured at the largest posterior extension of the buttocks .
arm circumference ( ac ) and forearm circumference ( fac ) were taken at the midpoints respectively .
skin fold thickness was measured on the subject 's body at 3 sites ( triceps , subscapular and calf ) with a large caliper ( cambridge , md ) .
the triceps skin fold ( tsf ) was measured in midline of the posterior aspect of the arm over the triceps muscles , midway between the lateral projections of acromion process of the scapula and the inferior margin of the ulna olecranon process . the subscapular skin folds ( ssf )
calf skin fold thickness was measured in the midline over the level of maximum protrusion . in each case a double thickness of skin and underlying tissue were raised and measured .
based on the who definition for cardiovascular disease risk , the following were accepted as cut - off points for obesity , bmi > 29.9 kg / m , wc>102 cm for men and 88 cm for women , whr > 1.0 in men and 0.85 in women .
whtr > 0.05 was used as a cut - off point . following who standard for definition of elevated blood pressure ; the following were accepted as elevated bp ; sbp > 140mmhg and/ or dbp > 90mmhg .
the population characteristics , anthropometric indicators , sbp and dbp for both rural and urban populations are shown as means and standard deviations .
pearson correlation between the blood pressure indicators with adiposity indicators were carried out and also differences between the various adiposity indications between the two populations were also noted using the t - test .

a total number of 567 individuals from the ages of 18 to 80 years were used for this study . 325 ( 57.3% ) of the individuals were males while 254 ( 42.7% ) were females .
the mean age of the study group was 33.6 + 14 years , and 33.7 + 14 and 33.5 + 13 years , for males and females respectively .
the mean ages of the males and females of the various groups and also the mean values of all the anthropometric measurements , blood pressure values , and obesity indicators have been summarized in table 1 .
summary of the means and standard deviations of the various anthropometric and blood pressure parameters by sex across the educational levels the largest mean value of subcutaneous fat for both males and females was noted in the primary education group , followed by the secondary education group .
the bmi assessment has the smallest mean value for both males and females in the tertiary education group . in the measurements of the central obesity indicators , the largest mean wc
was noted within the males and females of the primary education group while the least was noted in the tertiary education group
. both mean values of whr and whtr were noted to be smallest in the males and females of the tertiary education group .
the mean blood pressure values were also largest for the primary education group and least for the tertiary education group .
for all the indicators of subcutaneous fat ( ssf , tsf , csf , and sts ) , general obesity ( bmi ) , and central obesity ( wc , whr , whtr ) largest mean deposition of both subcutaneous , general and abdominal fats were noted amongst women of the primary education group .
the males showed larger mean bp values than the females in all the groups . in the summary of the obesity and cardiovascular disease risk occurrence , shown in table 2 ,
the primary education group was noted to be at most risk as against the tertiary education group .
prevalence of obesity and cardiovascular disease risk by various indicators by sex across educational levels the prevalence of obesity and cardiovascular disease risk was found to be highest amongst females of the primary education group .
all the obesity and blood pressure indicators used in this study ( wc , bmi , sbp , dbp , whr , whtr , sts ) showed inverse correlations with educational levels , which are significant for wc , sbp , dbp , and whtr .
the highest and most consistent relationship was noted with blood pressure ( sbp , dbp ) .
it is an important risk factor for major chronic diseases , such as diabetes , heart disease , stroke and certain cancers and its link with education and socio - economic status in the various communities and ethnicities has been the query of most researches .
education has been shown to be a major determinant of health status , particularly in poor countries .
varying results have been reported on the effect of education on obesity and blood pressure from the different researches on various ethnicities and countries .
higher mean values of the measured anthropometric dimensions and ratios were observed in the individuals that had little or no education than in those that had better education .
this same group also was more vulnerable to obesity and all the related cardiovascular disease risks .
both general , subcutaneous and abdominal obesities were worse for all the females of the various education group and worst for the females of the least educated group .
this work has noted a strong education gradient in obesity for the studied population with the education gradient in obesity being stronger in women than in men .
similar findings have being reported for other countries and ethnicities . increasing education at any point along that spectrum
cutler and lleras - muney found that those with more years of schooling are less likely to smoke , drink a lot , to be overweight or obese or to use illegal drugs .
grossman and kaestner in their work  effects of education on health  concluded that years of formal schooling is the most important correlate of good health .
various explanations have been proffered on the reasons for this strong relationship between education and obesity .
educated individuals have been reported to make better use of health related information than those who are less educated .
the lack of education about energy contents of foods has also been suggested to be a contributor to the effects of social class on obesity .
cutler and lleras - muney found that those with more years of schooling are less likely to smoke , drink a lot , to be overweight or obese or to use illegal drugs .
yoon suggested that it is possible that more highly educated people have the knowledge to develop healthy lifestyles and have more awareness of the health risks associated with being obese .
the positive effect of education on obesity can summarily be attributed to greater access to health - related information and improved ability to handle such information by the educated , clearer perception of the risks associated with lifestyle choices and improved self - control and consistency of preferences over time .
the establishment of a strong relationship between obesity and blood pressure within any community , group or country is important in the development of the most suitable education - based policies to counteract the present increase in obesity and related chronic diseases both in developed and developing communities and countries .
this relationship between education and health has been traced to the health information which is part of education .
so health education programs aimed at promoting healthy lifestyles might in principle generate similar effects to those associated with school education by providing relevant health information . to this effect government and other relevant policy making
bodies are called upon to intensify actions toward organizing and funding of public health education campaigns .
education , whether through formal schooling or health promotion campaigns , has been identified as one of the factors that can be used to combat the present increase in the prevalence of elevated blood pressure , obesity and obesity related diseases .
 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 .
