National Prevalence Of Overweight Research Articles

Slim north, fat south: explaining regional differences in abnormal weights in Nigeria.

Weight abnormalities (underweight, overweight, and obesity) can cause life-threatening ailments. This study investigates disparities in the prevalence of underweight, overweight, and obesity between northern and southern Nigeria and their associated factors. Using the 2018 Nigeria Demographic and Health Survey (NDHS), the study analysed a sample of 12,333 women with complete records of body mass index. The study found that southern women had lower odds of being underweight than women in the north, but the reverse was the case for overweight and obesity. The prevalence of underweight was 11.6%, and it varies from 6.9% in the southern state of Enugu to 31.6% in the northern state of Jigawa. The national prevalence of overweight was 17.9%, ranging from 6.7% in Jigawa State of the northern region to 39.9% in Lagos State of the south. Similarly, the prevalence of obesity in the north was 6.1% compared to 14.4% in the south, with Anambra State of the southern region recording the highest figure of 35.5% compared to 2.1% in the Yobe State of the northern region. In all, the rate of abnormal weight was significantly higher in the south than in the north. However, the type of weight abnormality varies between the two regions. Religion, education, use of contraceptives, and wealth were associated with the three forms of abnormal weights. However, while religion was significantly associated with obesity in the north, the association was not significant in the south. This study found that wealth and education have dissimilar influences on overnutrition. While the odds of being overweight and obese increase with wealth, being educated up to a secondary level significantly reduces the odds in Nigeria and across the two regions.

SPATIAL DISTRIBUTIONS AND RISK FACTORS OF OVERWEIGHT AND OBESITY AMONG WOMEN IN NIGERIA USING STRUCTURED GEO-ADDITIVE REGRESSION MODELS: ANALYSIS OF 2018 NIGERIA DEMOGRAPHIC HEALTH SURVEY

Overweight and obesity which are known to pose serious health problems are becoming increasingly prevalent in Nigeria which is a sub-Saharan African country. This study utilized the 2018 Nigeria Demographic Health Survey to examine demographic and socio-economic risk factors of overweight and obesity among Nigerian women aged 15-49 years. Exploratory analysis was used to provide basic description of the data while a semiparametric structured additive models was used to describe the relationship between the presumed factors and overweight and obesity status while also accounting for spatial effects at state level. The national prevalence of overweight and obesity among Nigerian women was found to be 27.4%. Increased risk of overweight and obesity among Nigerian women was found to be strongly associated with being older, high educational level, being rich, living in an urban area, having many children, being pregnant, and residing in southern part of Nigeria. In respect to ethnicity and religion, the Fulani tribe and Islamic religion were associated with lower prevalence of overweight and obesity. Overweight and obesity were found to be significantly more prevalent in the Southern parts compared to the Northern parts of Nigeria. The highest and lowest prevalence of overweight and obesity were observed in Anambra and Yobe states respectively. Prevalence of overweight and obesity was higher among Muslim women compared to Christian women since most Northern women are Muslims and most Southern women are Christians. Random (unstructured) spatial effects were significant indicating that overweigh/obesity was influenced by unobserved state specific factors

The Association Between Fast-Food Consumption and Physical Activity with Overweight Occurrence at School Among 9-11-Year-Old Children in Cakung Payangan Bekasi

Overweight occurs because of excessive energy intake stored in the form of fat tissue. The national prevalence of overweight and obesity among children aged 5­-12 years old was 10.8% and 8.8%, respectively. Several factors are responsible for increasing the prevalence of overweight, including food consumption and physical activity. The purpose of this study was to examine the association between fast-food consumption and physical activity with the overweight occurrence among school-aged children in Cakung Payangan, Bekasi. This is a cross-sectional study with a total of 80 students recruited through a simple random sampling method. There was a significant association between fast-food consumption and overweight (p = 0.013, CI 95% = 1,420 – 10,977). Also, there was a significant association between physical activity and overweight (p = 0.027, CI 95% = 1,023 – 74,825). Frequent fast-food consumption and mild physical activity have a significant relationship with overweight occurrence among school-aged children.

Combined alcoholic and non-alcoholic steatohepatitis.

SummaryWhile metabolic syndrome and alcohol consumption are the two main causes of chronic liver disease, one of the two conditions is often predominant, with the other acting as a cofactor of morbimortality. It has been shown that obesity and alcohol act synergistically to increase the risk of fibrosis progression, hepatic carcinogenesis and mortality, while genetic polymorphisms can strongly influence disease progression. Based on common pathogenic pathways, there are several potential targets that could be used to treat both diseases; based on the prevalence and incidence of these diseases, new therapies and clinical trials are needed urgently.

The Prevalence of Overweight, Obesity, Hypertension, and Diabetes in India: Analysis of the 2015-2016 National Family Health Survey.

Overweight, obesity, hypertension, and diabetes increase the risk of non-communicable diseases and all-cause mortality worldwide. Previous studies have not determined the prevalence of these conditions/diseases throughout India. Therefore, this study was aimed to address this limitation. Data on these conditions/diseases among men and women aged ≥ 18 years were obtained from the fourth National Family Health Survey conducted throughout India between January 2015 and December 2016. The prevalence and prevalence rate per 100,000 population were calculated at the national level and by age group, sex, and type of residence for each state and union territory. The national prevalence of overweight, obesity, hypertension, and diabetes were 14.6%, 3.4%, 5.2%, and 7.1%, respectively. The highest prevalence of these conditions/diseases at the national level was seen among those aged 35–49 years (54 years for men), especially women living in urban areas. In India, 1 out of every 7, 29, 19, and 14 individuals at the national level had overweight, obesity, hypertension, and diabetes, respectively—between 2015 and 2016. These results are important for the healthcare system and government policies in the future. Moreover, targeted efforts are required to establish public health strategies for the prevention, management, and treatment of these conditions/diseases throughout India.

Prevalence and Correlates of Overweight and Obesity among Preschool-Aged Children in San Luis Obispo County, 2006-2014

Background and Purpose: National prevalence of overweight and obesity (OW/OB) among children remains high; surveillance of OW/OB at state- and local-levels is needed. This study determines the prevalence and sociodemographic predictors of OW/OB among preschool-age children in San Luis Obispo (SLO) County. Methods: Cross-sectional convenience samples of Head Start, California State, and private preschools were surveyed in 2006 (n=482), 2009/10 (n=559), and 2014 (n=442). At all waves, preschool children aged 3-5 years were measured for height and weight using standardized stadiometer and digital scale protocols. In 2014, parents completed a demographics questionnaire. Results: Children assessed in 2009/10 and 2014 were more likely to be OW/OB than those assessed in 2006 (p=0.016). Unadjusted, bivariate odds ratios illustrated increased risk for OW/OB was associated with Hispanic ethnicity, residing in a lower income household, attending preschool in southern SLO County, and participation in a Head Start preschool. In the adjusted, multivariable model, increased risk for OW/OB was associated with attending preschool in SLO City and participation in a California State or Head Start preschool. Conclusion: OW/OB trends in SLO County are similar to national trends. Programs to continue to monitor and reduce socioeconomic disparity in OW/OB prevalence among young children are needed.

Overweight and obesity epidemic in Ghana-a systematic review and meta-analysis.

BackgroundIn many low and middle income countries (LMICs), the distribution of adulthood nutritional imbalance is shifting from a predominance of undernutrition to overnutrition. This complex problem poses a huge challenge to governments, non-state actors, and individuals desirous of addressing the problem of malnutrition in LMICs. The objective of this study was to systematically review the literature towards providing an estimate of the prevalence of overweight and obesity among adult Ghanaians.MethodsThis study followed the recommendations outlined in the PRISMA statement. Searches were performed in PubMed, Science Direct, google scholar, Africa Journals Online (AJOL) and the WHO African Index Medicus database. This retrieved studies (published up to 31st March 2016) that reported overweight and obesity prevalence among Ghanaians. All online searches were supplemented by reference screening of retrieved papers to identify additional studies.ResultsForty-three (43) studies involving a total population of 48,966 sampled across all the ten (10) regions of Ghana were selected for the review. Our analysis indicates that nearly 43% of Ghanaian adults are either overweight or obese. The national prevalence of overweight and obesity were estimated as 25.4% (95% CI 22.2–28.7%) and 17.1% (95% CI = 14.7–19.5%), respectively. Higher prevalence of overweight (27.2% vs 16.7%) and obesity (20.6% vs 8.0%) were estimated for urban than rural dwellers. Prevalence of overweight (27.8% vs 21.8%) and obesity (21.9% vs 6.0%) were also significantly higher in women than men. About 45.6% of adult diabetes patients in Ghana are either overweight or obese. At the regional level, about 43.4%, 36.9%, 32.4% and 55.2% of residents in Ashanti, Central, Northern and Greater Accra region, respectively are overweight or obese. These patterns generally mimic the levels of urbanization. Per studies’ publication years, consistent increases in overweight and obesity prevalence were observed in Ghana in the period 1998–2016.ConclusionsThere is a high and rising prevalence of overweight and obesity among Ghanaian adults. The possible implications on current and future population health, burden of chronic diseases, health care spending and broader economy could be enormous for a country still battling many infectious and parasitic diseases. Public health preventive measures that are appropriate for the Ghanaian context, culturally sensitive, cost-effective and sustainable are urgently needed to tackle this epidemic.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-3901-4) contains supplementary material, which is available to authorized users.

Obesity Drives Th17 Cell Differentiation by Inducing the Lipid Metabolic Kinase, ACC1

Chronic inflammation due to obesity contributes to the development of metabolic diseases, autoimmune diseases, and cancer. Reciprocal interactions between metabolic systems and immune cells have pivotal roles in the pathogenesis of obesity-associated diseases, although the mechanisms regulating obesity-associated inflammatory diseases are still unclear. In the present study, we performed transcriptional profiling of memory phenotype CD4 T cells in high-fat-fed mice and identified acetyl-CoA carboxylase 1 (ACC1, the gene product of Acaca) as an essential regulator of Th17 cell differentiation in vitro and of the pathogenicity of Th17 cells in vivo. ACC1 modulates the DNA binding of RORγt to target genes in differentiating Th17 cells. In addition, we found a strong correlation between IL-17A-producing CD45RO(+)CD4 T cells and the expression of ACACA in obese subjects. Thus, ACC1 confers the appropriate function of RORγt through fatty acid synthesis and regulates the obesity-related pathology of Th17 cells.

Global, regional, and national prevalence of overweight and obesity in children and adults during 1980–2013: a systematic analysis for the Global Burden of Disease Study 2013

In 2010, overweight and obesity were estimated to cause 3·4 million deaths, 3·9% of years of life lost, and 3·8% of disability-adjusted life-years (DALYs) worldwide. The rise in obesity has led to widespread calls for regular monitoring of changes in overweight and obesity prevalence in all populations. Comparable, up-to-date information about levels and trends is essential to quantify population health effects and to prompt decision makers to prioritise action. We estimate the global, regional, and national prevalence of overweight and obesity in children and adults during 1980-2013. We systematically identified surveys, reports, and published studies (n=1769) that included data for height and weight, both through physical measurements and self-reports. We used mixed effects linear regression to correct for bias in self-reports. We obtained data for prevalence of obesity and overweight by age, sex, country, and year (n=19,244) with a spatiotemporal Gaussian process regression model to estimate prevalence with 95% uncertainty intervals (UIs). Worldwide, the proportion of adults with a body-mass index (BMI) of 25 kg/m(2) or greater increased between 1980 and 2013 from 28·8% (95% UI 28·4-29·3) to 36·9% (36·3-37·4) in men, and from 29·8% (29·3-30·2) to 38·0% (37·5-38·5) in women. Prevalence has increased substantially in children and adolescents in developed countries; 23·8% (22·9-24·7) of boys and 22·6% (21·7-23·6) of girls were overweight or obese in 2013. The prevalence of overweight and obesity has also increased in children and adolescents in developing countries, from 8·1% (7·7-8·6) to 12·9% (12·3-13·5) in 2013 for boys and from 8·4% (8·1-8·8) to 13·4% (13·0-13·9) in girls. In adults, estimated prevalence of obesity exceeded 50% in men in Tonga and in women in Kuwait, Kiribati, Federated States of Micronesia, Libya, Qatar, Tonga, and Samoa. Since 2006, the increase in adult obesity in developed countries has slowed down. Because of the established health risks and substantial increases in prevalence, obesity has become a major global health challenge. Not only is obesity increasing, but no national success stories have been reported in the past 33 years. Urgent global action and leadership is needed to help countries to more effectively intervene.

Obesidad y cáncer en Chile: estimación de las fracciones atribuibles poblacionales

Obesity is a risk factor for the development of certain types of cancer.To estimate the proportion of cancers potentially attributable to obesity in men and women in Chile based on the calculation of population attributable fractions (PAF %).Cancer sites studied were those where obesity is a known risk factor based on the updated World Cancer Research Fund (WCRF) analysis. Namely, colorectal, endometrium, esophagus, breast, pancreas, kidney and gallbladder cancers were analyzed. Overall and specific PAFs% were calculated for cancer sites and sex from known estimates of relative risk and national prevalence of overweight and obesity.The overall estimates of cancer PAF% for obesity were approximately 20%, without differences between men and women. Highest cancer PAFs% were for endometrial (47%) in women, and esophageal (35%) and pancreatic (31%) in men. The largest sex differences in PAFs% were for gallbladder (higher in women) and colorectal (higher in men). Results are closer to those reported from developed countries (USA and United Kingdom) than those from developing countries (Brasil, China).In Chile about 20% of all cancers could be prevented by obesity prevention and control strategies.

Overweight among children decreased, but obesity prevalence remained high among women in South Africa, 1999–2005

The aim of the present study was to assess anthropometric status in South African children and women in 2005 in order to document temporal trends in selected anthropometric parameters. Heights and weights were measured in a cross-sectional study of children aged 1-9 years and women aged 16-35 years. The WHO reference values and BMI cut-off points were used to determine weight status. South Africa, representative sample based on census data. Children (n 2157) and women (n 2403). Stunting was the most common nutritional disorder affecting 21·7% of children in 1999 and 20·7% in 2005. The difference was not statistically significant. Underweight prevalence remained unchanged, affecting 8·1% of children, whereas wasting affected 5·8% of children nationally, a significant increase from 4·3% of children in 1999. Rural children were most severely affected. According to the international BMI cut-off points for overweight and obesity, 10% of children nationally were classified as overweight and 4% as obese. The national prevalence of overweight and obesity combined for women was 51·5%. The prevalence of overweight in children based on weight-for-height Z-score did not change significantly (8·0% to 6·8%, P = 0·138), but the combined overweight/obesity prevalence based on BMI cut-off points (17·1% to 14·0%, P = 0·02) decreased significantly from 1999 to 2005. The double burden of undernutrition in children and overweight among women is evident in South Africa and getting worse due to increased childhood wasting combined with a high prevalence of obesity among urban women, indicating a need for urgent intervention.

Prevalencia de sobrepeso y obesidad en niños menores de cinco años en el Perú 2007-2010

To estimate the prevalence of overweight and obesity in children under five in Peru in the years 2007-2010 and to describe according to geographical areas, poverty levels, maternal education, breastfeeding, child age, sex and birth weight. continuous (repeated cross-sectional) multistage, random sampling survey from the universe of children under five-years and pregnant women living in Peru, divided into five geographical areas. Out of 3,669 children, 50.3% were males (Lima N=680, Remaining Coast N=763, Urban Sierra N=719, Rural Sierra N=699, Jungle N=808) having their weight and height measured according to international standards. The national prevalence of overweight and obesity was 6.9%, with Metropolitan Lima (10.1%) as the highest and in the Jungle (2.6%) as the lowest. Age, sex, geographical area and birth weight were identified as risk factors through multiple logistic regression. overweight and obesity are higher in Lima, during the first year of age and when birth weight is more than 2.5 Kg.

Prevalence of overweight and obesity in the Netherlands

This paper shows the trends in the prevalence of overweight (body mass index [BMI] >or= 25 kg m-2) and obesity (BMI >or= 30 kg m-2) in the Netherlands. Overweight (obesity) prevalence in adult males increased from 37% (4%) in 1981 to 51% (10%) in 2004, and in adult females from 30% (6%) in 1981 to 42% (12%) in 2004, according to self-reported data. In boys and girls, obesity prevalence doubled or even tripled from 1980 to 1997, and again from 1997 to 2002-2004 a two- or threefold increase was seen for almost all ages. According to the most recent data, overweight (obesity) prevalence figures range, depending on age, from 9.2% to 17.3% (2.5-4.3%) in boys, and from 14.6% to 24.6% (2.3-6.5%) in girls. There is a lack of data on the national prevalence of overweight and obesity based on measured height and weight and on prevalences in different subgroups of the population. Regular national representative health examination surveys that measure height and weight are needed to assess the prevalence of overweight and obesity and its distribution over subgroups in the population, and to properly direct and evaluate prevention activities.

Prevalence of overweight and obesity among young people in Great Britain.

To determine the prevalence of overweight and obesity in British young people (4-18 years) in 1997. Cross-sectional analysis of the National Diet and Nutrition Survey of young people. Great Britain. Nationally representative sample of 1836 young people (age 4-18 years). The prevalence of obesity based on body mass index (weight/height(2)) and the International Obesity Task Force cut-offs was 4.0%, with a further 15.4% identified as overweight. Asians were almost four times as likely to be obese as white subjects (13.6 vs. 3.5%, P<0.001). Among white subjects there was no significant difference in the prevalence of obesity between girls and boys, or with age. The risk of obesity was significantly higher in subjects from social classes IV and V than from social classes I-III (6.5 vs. 2.7%, P=0.003). Subjects living in Scotland and Wales were significantly more likely to be obese than those in England (7.6 and 6.5 vs. 2.9%, respectively, P<0.01). Multiple logistic regression showed that, among white subjects, those in social classes IV and V living in Wales and Scotland were three times more likely to be obese than the other children in the survey (odds ratio 3.3, 95% confidence interval 1.1-9.8). These data provide information on the national prevalence of overweight and obesity in Great Britain and baseline data from which to monitor future trends. This analysis provides important demographic information on those most at risk of obesity, which may be used to inform public health strategies to prevent obesity in young people.

Factors associated with overweight and obesity in Mexican school-age children: results from the National Nutrition Survey 1999.

The objective of the study was to measure the prevalence of overweight and obesity in Mexican school-age children (5-11 years) in the National Nutrition Survey 1999 (NNS-1999). Overweight and obesity (defined as an excess of adipose tissue in the body) were evaluated through the Body Mass Index (BMI) in 10,901 children, using the standard proposed by the International Obesity Task Force. Sociodemographic variables were obtained using a questionnaire administered to the children's mothers. The national prevalence of overweight and obesity was reported to be 19.5%. The highest prevalence figures were found in Mexico City (26.6%) and the North region (25.6%). When adjusting by region, rural or urban area, sex, maternal schooling, socioeconomic status, indigenous ethnicity and age, the highest prevalences of overweight and obesity were found among girls. The risks of overweight and obesity were positively associated with maternal schooling, children's age and socioeconomic status. Overweight and obesity are prevalent health problems in Mexican school-age children, particularly among girls, and positively associated with socioeconomic status, age, and maternal schooling. This is a major public health problem requiring preventive interventions to avoid future health consequences.
