Page 4: Table 2 The values for mean BMI (SD) and overweight and obesity prevalence according to the IOTF cut-offs are revised. Page 5: Figure 2 The values for grade- and gender- specific mean BMI are revised. Page 6: Second paragraph Lines 1-8: "Prevalence of overweight by the IOTF cut-offs was twice the prevalence by the WHO 2007 reference (33% versus 17%) and prevalence of obesity by the IOTF cutoffs was three times higher than that calculated by the WHO 2007 reference (24% versus 7.5%). Using IOTF cut-offs for overweight and obesity in Pakistani schoolaged children would result in higher estimates than the WHO 2007 reference." should read "Prevalence of overweight by the IOTF cut-offs was half the prevalence by the WHO 2007 reference (8% versus 17%) and prevalence of obesity by the IOTF cutoffs was two-third of that calculated by the WHO 2007 reference (5% versus 7.5%). Using IOTF cut-offs for overweight and obesity in Pakistani schoolaged children would result in lower estimates than the WHO 2007 reference. A relatively lower overweight and obesity prevalence with use of the IOTF cut-offs as compared to the WHO reference had been reported elsewhere [2-3]." In present study, the estimates for overweight included obese children.     

Epidemiology of overweight and obesity and its determinants in Belo Horizonte (MG), Brazil: a cross-sectional population-based study]

OBJECTIVE: To determine the prevalence of overweight and obesity and to study potential risk factors for these conditions in persons over 18 years of age in the metropolitan area of Belo Horizonte, Brazil. METHODS: Data were obtained from a population-based study conducted in 1996 and 1997 by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística, IBGE) with a random sample of 1 105 individuals. Height and weight were measured by trained personnel. Overweight (body mass index [BMI] > or = 25.0 kg/m2) and obesity (BMI > or = 30.0 kg/m2) were the dependent variables. Bivariate analysis and multivariate logistic regression were used to identify potential risk factors for overweight and obesity. RESULTS: The prevalence of overweight and obesity was 31.1% (95% confidence interval 195% CI]: 27.3 to 35.2) and 5.7% (95% CI: 4.0 to 8.1), respectively, in men, and 25.9% (95% CI: 22.4 to 29.8) and 14.7% (95% CI: 11.9 to 17.9), respectively, in women. Multivariate analysis revealed that age and marital status were independent risk factors for overweight, whereas age, sex, and education were independent risk factors for obesity. Being female and well-educated showed a protective effect against overweight (odds ratio [OR] = 0.52; 95% CI: 0.33 to 0.83), but not against obesity (OR = 3.01; IC 95%: 1.14 to 7.94). Women with low education had a significantly greater risk (OR = 5.95; 95%CI: 2.51 to 14.12) of developing obesity than men having a high educational level. CONCLUSIONS: These results suggest that overweight and obesity may be serious public health problems in the metropolitan area of Belo Horizonte, Brazil. It is important to carry out further studies in order to explore the potential relationship between overweight and obesity on the one hand, and behavioral variables, such as smoking and alcohol consumption, on the other.     

A National Study of Obesity Prevalence and Trends by Type of Rural County

CONTEXT: Obesity is epidemic in the United States, but information on this trend by type of rural locale is limited. PURPOSE: To estimate the prevalence of and recent trends in obesity among US adults residing in rural locations. METHODS: Analysis of data from the Behavioral Risk Factor Surveillance System (BRFSS) for the years 1994-1996 (n = 342,055) and 2000-2001 (n = 385,384). The main outcome measure was obesity (body mass index [BMI] > or = 30), as determined by calculating BMI from respondents' self-reported height and weight. RESULTS: In 2000-2001, the prevalence of obesity was 23.0% (95% confidence interval [CI] 22.6%-23.4%) for rural adults and 20.5% (95% CI 20.2%-20.7%) for their urban counterparts, representing increases of 4.8% (95% CI 4.2%-5.3%) and 5.5% (95% CI 5.1%-5.9%), respectively, since 1994-1996. The highest obesity prevalence occurred in rural counties in Louisiana, Mississippi, and Texas; obesity prevalence increased for rural residents in all states but Florida over the study period. African Americans had the highest obesity prevalence of any group, up to 31.4% (95% CI 29.1%-33.6) in rural counties adjacent to urban counties. The largest difference in obesity prevalence between those with a college education compared with those without a high school diploma occurred in urban areas (18.4% [95% CI 17.9%-18.9%] vs 23.5% [95% CI 22.5%-24.5%], respectively); the smallest difference occurred in small, remote rural counties (20.3% [95% CI 18.7%-21.9%] versus 22.3% [95% CI 20.7%-24.0%], respectively). CONCLUSIONS: The prevalence of obesity is higher in rural counties than in urban counties; obesity affects some residents of rural counties disproportionately.

Diet composition and risk of overweight and obesity in women living in the southwestern United States

OBJECTIVE: It is unknown whether dietary patterns or macronutrient composition contribute to the observed differences in rates of overweight and obesity among Hispanic and non-Hispanic white women in the United States. We assessed the association of dietary patterns and macronutrient composition with overweight and obesity in Hispanic and non-Hispanic white women. DESIGN: Cross-sectional analysis of dietary data from a case-control study of breast cancer. PARTICIPANTS: Population-based control participants (871 Hispanic and 1,599 non-Hispanic white women) from the southwestern United States who completed the diet and other components of the interview and whose anthropometric measurements were available. MAIN OUTCOME MEASURES: Body mass index (BMI; calculated as kg/m(2)), weight status (overweight, BMI 25 to 29.9; obese, BMI>30). STATISTICAL ANALYSES PERFORMED: Dietary patterns were defined using factor analysis. Associations of dietary patterns and macronutrient composition with overweight and obesity as compared with normal weight were assessed with logistic regression. RESULTS: Hispanic women reported consuming more energy, a greater proportion of energy from fat and vegetable protein, less alcohol, and less energy from animal protein compared with non-Hispanic white women. Western and dieter patterns were associated with higher prevalence of overweight and obesity; the Prudent dietary pattern was associated with a 29% lower prevalence of overweight and a halving of the prevalence of obesity similarly in Hispanic and non-Hispanic white women. Higher proportions of energy from protein (odds ratio [OR] 1.81, 95% confidence interval [CI] 1.28 to 2.56) and animal protein (OR 2.10 95% CI 1.47 to 2.98) were associated with a greater risk of overweight; greater proportions of energy from fat (OR 2.28, 95% CI 1.27 to 4.08), protein (3.55 95% CI 2.38 to 5.29), or animal protein (3.44 95% CI 2.31 to 5.14) were associated with higher risk of obesity among non-Hispanic white women only. CONCLUSIONS: A Western dietary pattern was associated with greater risk and a Prudent diet with reduced risk of overweight and obesity. To reduce risk of overweight and obesity, Hispanic women should maintain healthful aspects of a native Hispanic diet, and non-Hispanic white women should replace animal protein with vegetable protein.     

Obesity and Overweight in Ethnic Minorities of the Detroit Metropolitan Area of Michigan

Race, ethnicity and socioeconomic factors influence the prevalence of obesity and overweight, which are major public health problems. Our objectives were (1) to calculate the prevalence of self-reported obesity and overweight in whites, blacks, Chaldeans, and Arabs in the Detroit metropolitan area; and (2) to examine the odds for self-reported overweight and obesity in the racial and ethnic minorities when compared to whites. The responses to a self-administered survey conducted among the adult residents (n = 2,883) of the Detroit metropolitan area of Michigan were analyzed. Prevalence of overweight and obesity were 47.4 and 34.6 % respectively for the whole sample, while it was 39.9 and 43.6 % for whites, 42.3 and 47.8 % for blacks, 46.2 and 30.3 % for Chaldeans, and 52.2 and 28.5 % for Arabs. The odds for obesity was significantly lower in Arabs [odds ratio (OR) 0.31; 95 % confidence interval (CI) 0.13–0.72] and Chaldeans (OR 0.14; 95 % CI 0.06–0.33) when compared to whites. Chaldeans (OR 0.36; 95 % CI 0.15–0.86) had significantly decreased likelihood for being overweight compared to whites. Odds for obesity and overweight can vary in the different ethnic minorities within whites. Sharing similar living conditions decreases the differences in the odds for overweight and obesity between whites and blacks. Taking into consideration the racial and ethnic differences of the target population may help in developing better programs for fighting overweight and obesity.     

Trends in overweight and obesity in Portugal: the National Health Surveys 1995-6 and 1998-9

OBJECTIVE: To assess overweight and obesity trends in the Portuguese population. RESEARCH METHODS AND PROCEDURES: National Health Surveys, conducted in 1995-6 (17,989 men; 20,249 women) and 1998-9 (17,923 men; 20,302 women), were used. RESULTS: In men, the prevalence of overweight and obesity increased from 39.9% (95% CI: 39.2 to 40.6) and 10.3% (95% CI: 9.9 to 10.7), respectively, in 1995-6, to 42.5% (95% CI: 41.8 to 43.2) and 11.5% (95% CI: 11.0 to 12.0), respectively, in 1998-9. In women, prevalence of obesity increased from 12.7% (95% CI: 12.2 to 13.2) in 1995-6 to 14.2% (95% CI: 13.7 to 14.6) in 1998-9, whereas the prevalence of overweight remained stable: 32.2% (95% CI: 31.6 to 32.9) in 1995-6 and 32.3% (95% CI: 31.6 to 32.9) in 1998-9. In men, prevalence of overweight and obesity were higher among former smokers and educational group of 6 to 12 years, and prevalence of obesity was higher in the Lisbon region. In women, prevalence of overweight and obesity were higher among never smokers, and prevalence of obesity was higher among educational group of -6 years. Prevalence of obesity was higher in the Alentejo region, and overweight was higher in the Center region. Finally, prevalence of obesity increased in both sexes for all strata studied (age, smoking status, educational level, and geographic region), whereas prevalence of overweight increased only in men. DISCUSSION: In Portugal, overweight and obesity levels are related to sociodemographic factors; the increase in obesity levels stresses the need for preventive measures.     

Supermarkets, other food stores, and obesity: the atherosclerosis risk in communities study

BACKGROUND: Obesity is a leading public health concern, and although environmental factors have been hypothesized to play a role in the prevention of obesity, little empirical data exist to document their effects. The purpose of this study was to examine whether characteristics of the local food environment are associated with the prevalence of cardiovascular disease risk factors. METHODS: A cross-sectional study of men and women participating in the third visit (1993-1995) of the Atherosclerosis Risk in Communities (ARIC) Study was conducted in 2004. The analyses included 10,763 ARIC participants residing in one of the 207 eligible census tracts located in the four ARIC-defined geographic areas. Names and addresses of food stores located in Mississippi, North Carolina, Maryland, and Minnesota were obtained from departments of agriculture. Multilevel modeling was used to calculate prevalence ratios of the associations between the presence of specific types of food stores and cardiovascular disease risk factors. RESULTS: The presence of supermarkets was associated with a lower prevalence of obesity and overweight (obesity prevalence ratio [PR] = 0.83, 95% confidence interval [CI] = 0.75-0.92; overweight PR = 0.94, 95% CI = 0.90-0.98), and the presence of convenience stores was associated with a higher prevalence of obesity and overweight (obesity PR = 1.16, 95% CI = 1.05-1.27; overweight PR = 1.06, 95% CI = 1.02-1.10). Associations for diabetes, high serum cholesterol, and hypertension were not consistently observed. CONCLUSIONS: Results from this study suggest that characteristics of local food environments may play a role in the prevention of overweight and obesity.

Overweight among children and adolescents in a Native Canadian community: prevalence and associated factors

BACKGROUND: The prevalence of pediatric obesity in North America is increasing. Native American children are at especially high risk. OBJECTIVES: The objective was to evaluate the prevalence of pediatric overweight and associated behavioral factors in a Native Canadian community with high rates of adult obesity and type 2 diabetes mellitus. DESIGN: Height and weight were measured in 445 children and adolescents aged 2-19 y. Fitness level, television viewing, body image concepts, and dietary intake were assessed in 242 subjects aged 10-19 y. Overweight was defined as a body mass index > or =85th percentile value for age- and sex-specific reference data from the third National Health and Nutrition Examination Survey (NHANES III). Multiple logistic regression was used to examine factors associated with overweight, with adjustment for age and sex. RESULTS: The overall prevalence of overweight in subjects aged 2-19 y was significantly higher than NHANES III reference data [boys: 27. 7% (95% CI: 21.8, 34.5); girls: 33.7% (95% CI: 27.9, 40.1)]. In the subset aged 10-19 y, > or =5 h television viewing/d was associated with a significantly higher risk of overweight than was < or =2 h/d [odds ratio (OR) = 2.52; 95% CI: 1.06, 5.98]. Subjects in the third and fourth quartiles of fitness had a substantially lower risk of overweight than did those in the first quartile [third quartile compared with first quartile: OR = 0.24 (95% CI: 0.09, 0.66); fourth quartile compared with first quartile: OR = 0.13 (95% CI: 0.03, 0. 48)]. Fiber consumption on the previous day was associated with a decreased risk of overweight (OR = 0.69; 95% CI: 0.47, 0.99 for each 0.77 g/MJ increase in fiber intake). CONCLUSIONS: Pediatric overweight is a harbinger of future diabetes risk and indicates a need for programs targeting primary prevention of obesity in children and adolescents.     

Childhood obesity in New York City elementary school students

OBJECTIVES: We estimated overweight and obesity in New York City elementary school children. METHODS: A multistage cluster sample of New York City public elementary school children was selected. Nurses measured children's height and weight and used a standard protocol to determine body mass index (BMI). Demographic information was obtained from official school rosters. Overweight and obese were defined as BMI-for-age at or above the 85th and 95th percentiles, respectively. RESULTS: Of 3069 sampled students, 2681 (87%) were measured. The prevalence of overweight was 43% (95% confidence interval [CI] = 39%, 47%), more than half of whom were obese. Overall prevalence of obesity was 24% (95% CI = 21%, 27%), with at least 20% obesity in each grade, including kindergarten. Hispanic children had significantly higher levels (31%; 95% CI = 29%, 34%) than Black (23%; 95% CI = 18%, 28%) or White children (16%; 95% CI = 12%, 20%). Asian children had the lowest level of obesity among all racial/ethnic groups (14.4%, 95% CI = 10.9, 18.7). CONCLUSIONS: Obesity among public elementary school children in New York City is an important public health issue. Particularly high levels among Hispanic and Black children mirror national trends and are insufficiently understood.

Prevalence of overweight, obesity and thinness in 9-10 year old children in Mauritius

ABSTRACT: OBJECTIVE: To document the prevalence of overweight, obesity and thinness in 9-10 year old children in Mauritius. METHODS: 412 boys and 429 girls aged 9-10 years from 23 primary schools were selected using stratified cluster random sampling. All data was cross-sectional and collected via anthropometry and self-administered questionnaire. Outcome measures were BMI (kg/m2), prevalence of overweight, obesity (International Obesity Task Force definitions) and thinness (low BMI for age). Linear and logistic regression analyses, accounting for clustering at the school level, were used to assess associations between gender, ethnicity, school location, and school's academic performance (average) to each outcome measure. RESULTS: The distribution of BMI was marginally skewed with a more pronounced positive tail in the girls. Median BMI was 15.6 kg/m2 in boys and 15.4 kg/m2 in girls, respectively. In boys, prevalence of overweight was 15.8% (95% CI: 12.6, 19.6), prevalence of obesity 4.9% (95% CI: 3.2, 7.4) and prevalence of thinness 12.4% (95% CI: 9.5, 15.9). Among girls, 18.9% (95% CI: 15.5, 22.9) were overweight, 5.1% (95% CI: 3.4, 7.7) were obese and 13.1% (95% CI: 10.2, 16.6) were thin. Urban children had a slightly higher mean BMI than rural children (0.5 kg/m2, 95% CI: 0.01, 1.00) and were nearly twice as likely to be obese (6.7% vs. 4.0%; adjusted odds ratio 1.6; 95% CI: 0.9, 3.5). Creole children were less likely to be classified as thin compared to Indian children (adjusted odds ratio 0.3, 95% CI: 0.2, 0.6). CONCLUSION: Mauritius is currently in the midst of nutritional transition with both a high prevalence of overweight and thinness in children aged 9-10 years. The coexistence of children representing opposite sides of the energy balance equation presents a unique challenge for policy and interventions. Further exploration is needed to understand the specific causes of the double burden of malnutrition and to make appropriate policy recommendations.     

Determinants of Childhood Obesity and Association with Maternal Perceptions of Their Children's Weight Status: The “GENESIS” Study

Prevention of early childhood obesity requires a clear understanding of its determinants. This study examined perinatal, parental, and lifestyle determinants of childhood obesity and how these factors are associated with maternal misperceptions of their children's weight status. The current work presents a cross-sectional analysis of 2,374 children, age 1 to 5 years, living in Greece (April 2003 to July 2004). The 2000 Centers for Disease Control and Prevention growth charts were used to classify children as overweight (≥85th and <95th body mass index [BMI]-for-age percentile for children older than 24 months) and obese (≥95th weight-for-length percentile for children younger than 24 months and ≥95th BMI-for-age percentile for children older than 24 months). Maternal perceptions about their children's weight status were assessed via interviews with the mothers. Early infancy growth data were obtained from pediatric medical records. The present study showed that the prevalence of overweight and obesity was 16.2% and 17.5%, respectively. Each unit increase of maternal and paternal BMI significantly increased the likelihood of childhood obesity by a factor of 1.03 (95% confidence interval [CI]: 1.01 to 1.07) and 1.15 (95% CI: 1.10 to 1.20), respectively. Furthermore, children with a rapid weight gain in infancy were 1.9 (95% CI: 1.3 to 2.7) times more likely to be overweight and 1.5 (95% CI: 1.2 to 1.9) times more likely to have their weight status underestimated by their mother. In conclusion, rapid infancy weight gain and higher parental BMI were the main determinants of obesity in preschool years. Maternal underestimation of children's weight status was more likely for children with rapid weight gain in infancy.     

Trend in the prevalence of obesity and overweight among Iranian children and adolescents: A systematic review and meta-analysis

ObjectiveChildhood obesity is an important predisposing factor for most non-communicable diseases. The aim of this review was to provide evidence on the prevalence and trends of childhood obesity and overweight in Iran.MethodsMultiple international and Iranian scientific databases were searched for relevant literatures. Two independent reviewers identified relevant papers in several steps. Separate meta-analyses (using fixed- or random-effect models) were performed to estimate the overall, age, sex, and age–sex specific prevalence of obesity and overweight. Stratified analysis based on Centers for Disease Control and Prevention, International Obesity Task Force, and World Health Organization definition criteria and study year also were performed.ResultsWe included 107 studies in the meta-analysis (49 English and 58 Persian). Based on Centers for Disease Control and Prevention definition criteria, the overall prevalence of obesity and overweight remained relatively constant in the 2000s and are estimated to be about 5.1% (95% confidence interval [CI], 4.4–5.8) and 10.8% (95% CI, 10.2–11.4), respectively. The meta-regression analysis showed that the prevalence of obesity and overweight did not vary significantly with respect to sex and age of study participants. Girls had a lower prevalence of obesity and higher prevalence of overweight than boys.ConclusionThis review, which is the first of its kind in the Middle East and North Africa, suggests that although the trend in the prevalence of childhood obesity in Iranian children is not considerably high, but the escalating trend of excess weight among young children is alarming and should be considered by providers of interventional preventive programs at national and regional levels.     

生命早期营养不良对成年后超重和肥胖患病危险影响的研究

目的 研究生命早期食物短缺及营养不良对成年后超重和肥胖患病危险的影响，对成年人慢性病的原因溯源，为国家制订妇女儿童营养改善政策提供科学依据。方法 应用2002年中国居民营养与健康状况调查资料，将三年自然灾害（1959—1961年）出生的研究对象作为受灾害影响人群，将灾害之后（1964年）出生的人群作为未受灾害影响人群（对照组），比较两组人群平均体重指数（BMI）及超重和肥胖患病率，并计算受灾害影响组人群患超重和肥胖的相对危险度（OR）。结果1959—1961年出生女性的BMI均值显著高于未受灾害影响的1964年出生的女性（P〈0．01），调整地区等因素后，1959—1961年出生女性的超重患病率均显著高于1964年出生的对照组女性（P〈0．05）；1959、1960年出生女性的肥胖患病率显著高于1964年出生的对照组女性（P〈0．05）。与1964年出生女性比较，生命早期受灾害影响的1959—1961年出生女性患超重的危险性分别增加28．9％（OR值95％CI为1．063～1．565）、37．2％（OR值95％CI为1．136～1．658）、35．2％（OR值95％CI为1．103～1．657），1959、1960年出生女性患肥胖的危险性分别增加46．5％（OR值95％CI为1．088～1．972）、39．6％（OR值95％CI为1．039～1．876）。而男性四组之间的平均BMI水平、超重和肥胖患病率的差异均无统计学意义（P〉0．05）。结论 生命早期遭受食物供应不足及营养不良可能会使成年后患超重和肥胖的危险性增加，制订适合国情的妇女、儿童营养改善政策，特别是控制新生儿低体重的有效措施对预防成年后慢性病的发生具有重要意义。     

Prevalence and Socio-Demographic Determinants of Overweight and Obesity in a Nigerian Population

Objective

This survey explored prevalence of overweight and obesity and their associations with socio-demographic variables in a Nigerian population.

Methods

This cross-sectional survey involved 1521 adults in Nnewi. Age, sex, educational and occupational status, and BMI were recorded.

Results

Prevalence of overweight was higher in males (32.3%; 95% CI, 29.5%–35.2%) than in females (29.8%; 95% CI, 26.8%–33.0%); the reverse was the case for prevalence of obesity (19.6%; 95% CI, 17.3%–22.2% in males and 36.0%; 95% CI, 32.8%–39.4% in females). Higher odds ratios (ORs) for overweight and obesity were observed in participants aged 41–60 years (OR 2.03; 95% CI, 1.57–2.61 for overweight and OR 4.29; 95% CI, 3.25–5.67 for obesity) and those >60 years (OR 1.72; 95% CI, 1.21–2.43 for overweight and OR 4.21; 95% CI, 2.86–6.19 for obesity) compared to those aged 18–40 years. Female sex was associated with higher ORs for overweight (OR 1.20; 95% CI, 0.96–1.51) and obesity (OR 2.21; 95% CI, 1.73–2.83). Participants with secondary education had marginally higher ORs for overweight (OR 1.15; 95% CI, 0.88–1.51) and obesity (OR 1.17; 95% CI, 0.86–1.59) than those with tertiary education, and so were those with primary education for obesity (OR 1.19; 95% CI, 0.74–1.89) but higher OR for overweight (OR 1.44; 95% CI, 0.98–2.13). Unskilled participants had about the same OR for overweight and obesity as professionals, and while skilled participants had about the same OR for overweight as professionals, their OR for obesity (OR 1.27; 95% CI, 0.67–2.43) was fairly higher than that for professionals.

Conclusions

Prevalence of overweight is higher in males than in females, but the reverse is the case for prevalence of obesity. Older age and female sex are associated with increased risk of overweight and obesity, while working at a skilled occupation is associated with obesity, and tertiary educational attainment is associated with overweight.Key words: determinants, obesity, overweight, prevalence, developing country     

秦皇岛市北戴河区居民肥胖与相关慢性疾病的影响因素

目的研究秦皇岛市北戴河区肥胖与相关慢性疾病的影响因素。方法采用随机抽样方法,于2010年8—10月对北戴河区20～92岁居民进行面对面调查,抽取3 569人,用询问调查法获得个人基本情况和相关因素,测量身高、体重。结果超重、全身性肥胖和腹型肥胖总患病率分别为36.79%、13.28%和54.08%;不同性别的人群超重率、全身性肥胖率和腹型肥胖率差异有统计学意义(χ2=126.31,P0.01;χ2=63.85,P0.01;χ2=14.91,P0.01);不同年龄人群超重率、全身性肥胖率和腹型肥胖率差异有统计学意义(χ2=93.15,P0.01;χ2=6.002,P=0.01;χ2=24.70,P0.01);不同文化程度的人群超重率、全身性肥胖率和腹型肥胖率差异有统计学意义(χ2=9.49,P0.01;χ2=126.31,P0.01;χ2=13.11,P0.01);与体重正常人群比较,超重和肥胖人群高血压、血糖异常和甘油三酯升高危险性较高,其OR值分别为2.86,2.94,3.52和5.06,4.19,6.37)。结论肥胖者易患高血压、血糖异常、血脂异常等慢性疾病,应采取有效的措施预防和控制肥胖。     

Relationship between body mass and gastro-oesophageal reflux symptoms: The Bristol Helicobacter Project

OBJECTIVE: To examine the relationship between body mass and gastro-oesophageal reflux in a large population-representative sample from the UK. DESIGN AND SETTING: Cross-sectional population-based study, as part of a randomized controlled trial of eradication of Helicobacter pylori infection, in Southwest England. Subjects In all, 10 537 subjects, aged 20-59 years, were recruited from seven general practices. Subjects provided data on frequency and severity of dyspeptic symptoms and anthropometric measurements were taken. MAIN OUTCOME MEASURE: Relationship between overweight (body mass index [BMI] >/=25 kg/m(2) and 30 kg/m(2)) and frequency and severity of heartburn and acid regurgitation. RESULTS: Body mass index was strongly positively related to the frequency of symptoms of gastro-oesophageal reflux. The adjusted odds ratios (OR) for frequency of heartburn and acid regurgitation occurring at least once a week in overweight participants compared with those of normal weight were 1.82 (95% CI: 1.33-2.50) and 1.50 (95% CI: 1.13-1.99) respectively. Corresponding OR (95% CI) relating to obese patients were 2.91 (95% CI: 2.07-4.08) and 2.23 (95% CI: 1.44-3.45) respectively. The OR for moderate to severe reflux symptoms were raised in overweight and obese subjects but not to the same extent as frequency of symptoms and only the relationship between obesity and severity of heartburn reached conventional statistical significance: OR = 1.19; 95% CI: 1.07-1.33. CONCLUSIONS: Being above normal weight substantially increases the likelihood of suffering from heartburn and acid regurgitation and obese people are almost three times as likely to experience these symptoms as those of normal weight.
