Associations of body mass index and obesity with physical activity, food choices, alcohol intake, and smoking in the 1982-1997 FINRISK Studies

BACKGROUND: Recent increases in the prevalence of obesity worldwide are suggested to be caused largely by an environment that promotes sedentariness and excessive food intake. OBJECTIVE: We investigated associations of body mass index (BMI) and obesity with physical activity, food choices, alcohol consumption, and smoking history. In addition, we examined the consistency of these associations over time, with the aim of assessing whether the significance of lifestyle variables as correlates of obesity increased over a 15-y period. DESIGN: Independent cross-sectional surveys were carried out in 1982, 1987, 1992, and 1997. Altogether, 24604 randomly selected men and women (aged 25-64 y) participated in these surveys. The subjects' weights and heights were measured, and data on lifestyle were collected with self-administered questionnaires. RESULTS: In men and women, perceived general health, leisure-time physical activity, and daily vegetable consumption were inversely associated with obesity, as were bread consumption in women and activity at work in men. Consumption of sausages, milk, and sour milk and heavy work (in women only) were positively associated with obesity. Obesity was also associated with alcohol consumption and smoking history. Most associations were constant over the 15-y period. However, the inverse associations of BMI with physical activity in women and with perceived health in men seemed to strengthen over time. CONCLUSIONS: A physically active lifestyle with abstention from smoking, moderate alcohol consumption, and consumption of healthy foods maximizes the chances of having a normal weight. The significance of avoiding sedentariness increases over time as a factor associated with normal weight.     

Association between Emotional Eating and Frequency of Unhealthy Food Consumption among Taiwanese Adolescents

Emotional eating is one factor that increases the consumption of unhealthy food. This study aimed to investigate the association between emotional eating and frequencies of consuming fast food, high-fat snacks, processed meat products, dessert foods, and sugar-sweetened beverages (SSBs) in adolescents. The baseline survey data (2015) from the Taiwan Adolescent to Adult Longitudinal Study (TAALS) were fitted into multivariate logistic regression models adjusted for sex, school type, Body Mass Index (BMI), eating while doing something, nutrition label reading, skipping breakfast, smoking, binge drinking, sedentary lifestyle, physical activity, peer and school support, and parental education level. Among the 18,461 participants (48.5% male and 51.5% female), those exhibiting emotional eating were more likely to consume fast food (Odds ratio (OR) = 2.40, 95% Confidence interval (CI): 2.18–2.64), high-fat snacks (OR = 2.30, 95% CI: 2.12–2.49), processed meat products (OR = 1.92, 95% CI: 1.78–2.08), dessert foods (OR = 2.49, 95% CI: 2.31–2.69), and sugar-sweetened beverages (OR = 1.83, 95% CI: 1.70–1.98). Factors that were positively associated with unhealthy food consumption included eating while doing other activities, binge drinking, smoking, and sedentary lifestyle. Among all the covariates, nutrition label reading was the only factor that was inversely associated with frequent unhealthy food consumption. Sex and school type may moderate the effect of emotional eating on the frequent consumption of specific unhealthy food groups. In conclusion, adolescents with high emotional eating were more likely to report frequent consumption of unhealthy foods in Taiwan. Our findings showed that male participants appeared to consume fast foods, high-fat snacks, processed meat, and SSBs more often and dessert foods less often than females. Future longitudinal studies are recommended for understanding the causal relationship between emotional eating and unhealthy food consumption.     

Lifestyle Patterns Are Associated with Elevated Blood Pressure among Qatari Women of Reproductive Age: A Cross-Sectional National Study

Women of childbearing age are particularly vulnerable to the adverse effects of elevated blood pressure (BP), with dietary and lifestyle habits being increasingly recognized as important modifiable environmental risk factors for this condition. Using data from the National STEPwise survey conducted in Qatar in year 2012, we aimed to examine lifestyle patterns and their association with elevated BP among Qatari women of childbearing age (18–45 years). Socio-demographic, lifestyle, dietary, anthropometric and BP data were used (n = 747). Principal component factor analysis was applied to identify the patterns using the frequency of consumption of 13 foods/food groups, physical activity level, and smoking status. Multivariate logistic regression analyses were used to evaluate the association of the identified lifestyle patterns with elevated BP and to examine the socio-demographic correlates of these patterns. Three lifestyle patterns were identified: a “healthy” pattern characterized by intake of fruits, natural juices, and vegetables; a “fast food & smoking” pattern characterized by fast foods, sweetened beverages, and sweets, in addition to smoking; and a “traditional sedentary” pattern which consisted of refined grains, dairy products, and meat in addition to low physical activity. The fast food & smoking and the traditional & sedentary patterns were associated with an approximately 2-fold increase in the risk of elevated BP in the study population. The findings of this study highlight the synergistic effect that diet, smoking and physical inactivity may have on the risk of elevated BP among Qatari women.     

Prevalence of Obesity and Factors Associated with it in a Worksite Setting in Malaysia

Socio-economic status, lifestyle behaviors, and psychosocial factors have been implicated in the development of overweight and obesity. This study aims to observe the prevalence of overweight and obesity in an academic worksite and to examine the possible association between variables such as socio-economic characteristics, work factors, psychosocial factors, and weight control behaviors and obesity. In this study, the target population were full-time academic and non-academic staff. Body mass index (BMI) and waist circumference (WC) were computed to determine obesity. A pretested self-administered questionnaire was used to obtain information on socio-demographic factors, work related factors, psychosocial factors, and weight control behaviors. Data were obtained on 367 adults of whom 39.2% were males and 60.8% females. Overweight was seen in 31.9% of males and 26.5% of females while 16.1% of them were obese, irrespective of gender. Central obesity was noted in about 37% of males and 39% of females. The results showed that socio-demographic factors (age, gender, and education) and psychosocial factors (perceived health status, body weight perception, and weight-control goals) were significantly associated with BMI. Working hours were also significantly associated with BMI. However, weight control practices (diet-control practices and physical activity practices) were not significantly associated with BMI. In conclusion, this study found a higher prevalence of overweight and obesity among employees of a selected public university in comparison to the general population. Socio-demographic, psychosocial factors, and working hours were found to contribute to obesity in this sample of adults.     

Prevalence of obesity and associated risk factors in a Turkish population (trabzon city, Turkey)

OBJECTIVE: To estimate the prevalence of overweight and obesity (general and central) in the Trabzon Region and its associations with demographic factors (age, sex, marital status, reproductive history in women, and level of education), socioeconomic factors (household income and occupation), family history of selected medical conditions (diabetes, hypertension, and obesity), lifestyle factors (smoking habits, physical activity, and alcohol consumption), and hypertension in the adult population. RESEARCH METHODS AND PROCEDURES: A sample of households was systematically selected from the central province of Trabzon and its five towns, namely, Sürmene, Vakfikebir, Ma?ka, Hayrat, and Tonya. A total of 5016 subjects (2728 women and 2288 men) were included in the study. Individuals more than 20 years old were selected from their family health cards. Demographic factors, socioeconomic factors, family history of selected medical conditions, and lifestyle factors were obtained for all participants. Systolic blood pressure and diastolic blood pressure levels were measured for all subjects. Study procedures were carried out in the local health centers in each town over an 8-month period. Obesity was defined as BMI > or = 30 kg/m2 and overweight as BMI = 25.0 to 29.9 kg/m2. RESULTS: The prevalence of obesity was 23.5%: 29.4% in women and 16.5% in men. The combined prevalence of both overweight and obesity was 60.3%. The prevalence of abdominal obesity was 29.4%: 38.9% among women and 18.1% among men. The prevalence of obesity increased with age, being highest in the 60- to 69-year-old age group (40.8%) but lower again in the 70+ age group. Obesity was associated positively with marital status, parity, cessation of cigarette smoking, alcohol consumption, and household income and inversely with level of education, cigarette use, and physical activity. Also, obesity was associated positively with hypertension. DISCUSSION: In the Trabzon Region, 60.3% of the adult population presents with some excess weight. Obesity is a major public health problem that requires generalized interventions to prevent it among the adult population.     

Overweight and obesity: the role of education, employment and income in Spanish adults

OBJECTIVE: To study the relationship between obesity prevalence and education, employment and socioeconomic levels to improve the designing of intervention programs. METHODS: Cross-sectional population-based study on 2640 subjects over 15 years of age in Spain. Through interviews conducted in subjects' homes we have obtained socio-demographic, anthropometric data, and information on physical activity, life styles and eating habits. Statistically, we have used prevalence ratios with confidence intervals and logistic regressions. RESULTS: The prevalence of overweight and obesity is 36.4% (IC95% 34.5-38.2) and 17% (IC95% 15.7-18.5), respectively, higher in men, and increasing with age. Obesity prevalence is independent of education level. Higher prevalence of overweight and obesity are found in the lowest occupational categories, and there is an inverse relationship between BMI and employment situations. Obesity is more prevalent in retired people and people that work from home, compared with professions that require activity at work. The association found between obesity and socioeconomic characteristics of the population is different in men and women: in women only, this risk was found to be associated with low or primary education levels (OR 2.4, 1.5-4.0), being unemployed or working at home (OR 1.6, 1.08-2.4) and having a medium income (OR 1.87, 1.03-3.33). CONCLUSIONS: We have confirmed a high prevalence of overweight and obesity in our area. Socioeconomic variables have a more predictive value in women than in men.     

Obesity of Czech children and adolescents: relation to parental obesity and socioeconomic factors

The purpose of this study was to estimate the change in overweight and obesity prevalence and the influence of socioeconomic status and parental obesity on overweight and obesity of children and adolescents in the Czech Republic. The roles of family history of obesity, dietary factors and physical activity were evaluated. The quota sample of 1,417 children and adolescents aged 6.00–17.99 years was examined in November 2005 as a part of the survey Lifestyle and Obesity. The quota sample was nationally representative, and subjects were selected according to the gender, age, region, size of residential location and education of parents. In the subjects weight, height and waist circumferences were measured and BMI was calculated. Food intake and physical activity were estimated by food frequency and physical activity questionnaires. The results were compared with the data from the 6th National Anthropological Survey of Children and Adolescents 2001, the Czech Republic. The data was evaluated by Pearson’s chi-square test and by linear regression analysis with backward factor reduction. Enhancing prevalence of obesity was found in younger age categories in comparison with the year 2001. Parental overweight and obesity significantly increased the risk of overweight and obesity. BMI in children (6–12.99 years) was associated with the intake of sweetened carbonated drinks and potatoes including fried ones (positive association) and low-sugar carbonated drinks and physical activity (negative association). In adolescents (13–17.99 years) BMI was associated with parental obesity, fat meat intake, time spent on the computer (positive association) and fish intake and physical activity (negative association). The results show an increase in obesity prevalence in younger children in the Czech Republic. Parental obesity significantly enhanced the risk ratio of obesity predominantly in adolescents.     

Late-Night Overeating or Low-Quality Food Choices Late at Night Are Associated with Subclinical Vascular Damage in Patients at Increased Cardiovascular Risk

Late-night overeating (LNO) is associated with several cardiovascular disease (CVD) risk factors. Limited data exist regarding the association between late-night (LN) systematic food consumption, LNO, and LN poor food quality with subclinical vascular damage (SVD) which precedes the onset of CVD. This study aimed to investigate the above associations with SVD in a large sample of adults, free of established CVD, with one or more CVD risk factors. In total, 901 adults (45.2% males) underwent anthropometric, dietary (through two 24 h dietary recalls) and vascular assessment. LN systematic eating was defined as consumption of food after 19:00 h in both dietary recalls and LNO was defined as systematic consumption of >40% of daily total energy intake (dTEI) after 19:00 h. Systematic LN food consumption was inversely associated with diastolic blood pressure (DBP) (−1.44 95% C.I. (−2.76, −0.12)) after adjusting for age, sex, hypertension, diabetes, dyslipidemia, smoking, BMI and dTEI. LNO was positively associated with existence of carotid plaques (1.70 95% C.I. (1.07, 2.68)), while LN increased consumption of red meat, refined grains and wine and low consumption of whole wheat grains was positively associated with Aix (Augmentation Index) (0.84 95% C.I. (0.09, 1.59)), after adjusting for all the mentioned confounders. Systematic LN eating is associated with lower DBP while systematic LNO and consumption of poor-quality food late at night, is associated with SVD. Further research is needed to define more accurately the impact of LN eating habits on vascular health.     

Lifestyle patterns associated with diet, physical activity, body mass index and amount of recent weight loss in a sample of successful weight losers

ABSTRACT: BACKGROUND: Research suggests that the interaction between biological susceptibility and environmental risk is complex and that further study of behavioral typologies related to obesity and associated behaviors is important to further elucidate the nature of obesity risk and how to approach it for intervention. The current investigation aims to identify phenotypical lifestyle patterns that might begin to unify our understanding of obesity and obesity related behaviors. METHODS: Individuals who had recently lost substantial weight of their own initiative completed measures of intentional weight control behaviors and lifestyle behaviors associated with eating. These behaviors were factor analyzed and the resulting factors were examined in relation to BMI, recent weight loss, diet, and physical activity. RESULTS: Four meaningful lifestyle and weight control behavioral factors were identified-- regularity of meals, TV related viewing and eating, intentional strategies for weight control, and eating away from home. Greater meal regularity was associated with greater recent weight loss and greater fruit and vegetable intake. Greater TV related viewing and eating was associated with greater BMI and greater fat and sugar intake. More eating away from home was related to greater fat and sugar intake, lower fruit and vegetable intake, and less physical activity. Greater use of weight control strategies was most consistently related to better weight, diet, and physical activity outcomes. CONCLUSIONS: Compared to the individual behavior variables, the identified lifestyle patterns appeared to be more reliably related to diet, physical activity, and weight (both BMI and recent weight loss). These findings add to the growing body of literature identifying behavioral patterns related to obesity and the overall weight control strategy of eating less and exercising more. In future research it will be important to replicate these behavioral factors (over time and in other samples) and to examine how changes in these factors relate to weight loss and weight maintenance over time.     

Relationship between eating behaviours and food and drink consumption in healthy postmenopausal women in a real-life context

Associations between eating behaviours and dietary variables have not been thoroughly investigated in healthy postmenopausal women in a real life uncontrolled context. To investigate how eating behaviours (cognitive dietary restraint, disinhibition and susceptibility to hunger) were associated with food and drink consumption, energy density and meal pattern in 112 healthy postmenopausal women (age 56.8 (SD 4.4) years) not on.hormonal therapy. Women completed a 3 d weighed food record and filled out the Three-Factor Eating Questionnaire. The sample was divided according to the median of the distribution of cognitive dietary restraint and disinhibition (9 and 6 respectively). Both subgroups of women with high restraint level (presenting either high or low disinhibition) consumed a diet with a lower energy density than subgroups of women with lower restraint level. Women with high restraint-low disinhibition had a lower consumption of red meat and processed meat and a lower consumption of diet soft drinks than women with low restraint-high disinhibition. They were also characterised by a higher intake of whole grains than women with high restraint-high disinhibition and than women with lower restraint level (with either high or low disinhibition). Women with high restraint-high disinhibition levels showed differences in dietary variables when compared with subgroups of women with lower restraint level, namely for refined grains and diet soft drinks. We conclude that in healthy postmenopausal women, dietary consumption of specific food and drink may be related to particular eating behaviours. Women with high restraint and low disinhibition levels generally showed the most healthy dietary pattern.     

Faster self-reported speed of eating is related to higher body mass index in a nationwide survey of middle-aged women

This study is the first nationwide population survey to explore the association between speed of eating and degree of obesity. The objective was to cross-sectionally examine the relationship between self-reported speed of eating and body mass index (BMI; calculated as kg/m²) in a nationally representative sample of New Zealand women. In May 2009, a sample of 2,500 New Zealand women aged 40 to 50 years was randomly selected from the nationwide electoral rolls. A 66% participation rate was achieved. Potential participants were mailed a self-administered questionnaire containing questions on self-reported speed of eating, demographics, health conditions, menopause status, physical activity, height, and weight. Univariate models were used to examine the associations between demographic, health and behavioral variables, and BMI, while a multivariate model was developed to investigate the relationship between self-reported speed of eating and BMI. After adjusting for age, smoking status, menopause status, thyroid condition, ethnicity, socioeconomic status, and physical activity, BMI statistically significantly increased by 2.8% (95% confidence interval: 1.5% to 4.1%; P<0.001) for each category increase in self-reported speed of eating. Although the direction of causality requires confirmation in longitudinal and randomized intervention studies, the results suggest that faster eating is associated with higher BMI in middle-aged women.     

Fish consumption among pregnant women in London, Ontario: associations with socio-demographic and health and lifestyle factors

BACKGROUND: Intake of fish and omega-3 fatty acids is inversely related to adverse health outcomes; however, these relationships may be confounded by socio-economic status and health behaviours. This study's purpose was to describe the socio-demographic, health and lifestyle correlates of fish consumption among pregnant women. METHODS: Pregnant women (n=2394) completed a telephone interview between 10-22 weeks' gestation (London, Ontario, 2002-5) containing questions on socio-demographic, health and lifestyle variables; dietary intake was measured using a 106-item validated food-frequency questionnaire. Unadjusted and adjusted risk ratios were obtained using a modified Poisson regression model. RESULTS: Infrequent fish consumption, <1/week, was reported by 32% of women. After adjusting for age and education, infrequent fish consumption was associated with education 相似文献   

Is Physical Activity Protective against Emotional Eating Associated Factors during the COVID-19 Pandemic? A Cross-Sectional Study among Physically Active and Inactive Adults

Physical activity levels during the COVID-19 pandemic have been decreasing and this may be a risk factor for development of emotional eating and its associated factors. The aim of the study was to analyze the factors associated with emotional eating among individuals with different physical activity levels during the COVID-19 pandemic. Data relating to the pandemic on physical activity, emotional eating, sociodemographic data, perceptions about lifestyle habits, body satisfaction, and perceptions about eating habits and food consumption were collected. Factors associated with emotional eating in the group of active and inactive individuals were observed using multiple linear regression controlled for age, sex, BMI, and monthly income. Emotional eating for the active group was associated with perceived stress, body dissatisfaction, and increased consumption of sweets and desserts. In addition to these factors found among the active group, working or studying >8 h/day, sleep worsening, increased amount of food consumed, increased purchase of food through delivery, and increased vegetable consumption were also associated with emotional eating for the inactive group. These findings suggest a potential protective role of physical activity in the appearance of factors associated with emotional eating during the COVID-19 pandemic.     

Determining lifestyle correlates of body mass index using multilevel analyses: the Tromsø Study, 1979-2001

Increases in overweight and obesity have been observed globally in both developed and developing countries. The authors assessed the relation between lifestyle factors and body mass index (BMI) (weight (kg)/height (m)2) in a population-based longitudinal study, using BMI and its subsequent change as responses in a multilevel model. The authors included 11,115 men and women aged 20-61 years at baseline who were living in the municipality of Troms?, Norway, and who participated in three or four consecutive health surveys between 1979-1980 and 2001. Baseline age, physical activity at work, coffee consumption, and desired BMI (i.e., the BMI that the subjects reported they would like to have) were positively associated with baseline BMI, whereas height, alcohol consumption, leisure-time physical activity, and level of education were inversely associated. Most relations were found to be stronger in women than in men. Clinically relevant effect sizes were observed for most of the significant associations, especially in women. For instance, on an ordinal scale, a one-category increase in educational level would decrease the mean baseline BMI among women by 0.30 kg/m2. Significant associations between several lifestyle factors and subsequent BMI change revealed that observed baseline associations were strengthened over time, especially in women.     

Dietary patterns are associated with body mass index in a Korean population

Changes in dietary habits may be associated with the increased prevalence of obesity in South Korea. Therefore, we aimed to identify major dietary patterns and to evaluate the association between these patterns and body mass index (calculated as kg/m²) in a Korean population. Typical dietary intake was assessed using a food frequency questionnaire in a cross-sectional study of 1,118 subjects aged 30 to 70 years who underwent health screening examinations. Dietary patterns were derived from 39 predefined food groups using factor analysis. A body mass index >27.5 was used as an indicator of obesity. Logistic regression was used to evaluate the association between obesity and dietary patterns. Three dietary patterns (vegetable-seafood, meat-fat, and snack) were identified and seem to be closely associated with lifestyle factors, including physical activity, smoking, and alcohol consumption. In the multivariate logistic regression model, the meat-fat dietary pattern was positively associated with obesity (odds ratio for high tertile vs low tertile intake=2.78 [95% confidence interval: 1.43 to 5.42]; P for trend=0.008), whereas the vegetable-seafood and snack dietary patterns showed no association with obesity. Results suggest that diets high in meat, oil, and sugar may be associated with obesity status in Korean adults.     

Adherence to the Mediterranean dietary pattern among the population of the Balearic Islands

The aim of the present study was to assess the prevalence of the Mediterranean dietary pattern (MDP) in the population of the Balearic Islands and socio-demographic and lifestyle factors that might determine adherence to the MDP. A cross-sectional nutritional survey was carried out in the Balearic Islands between 1999 and 2000. A random sample (n 1200) of the adult population (16-65 years) was interviewed. Dietary questionnaires incorporating questions related to socio-economic status, education level, lifestyle factors and health status were utilised. Dietary habits were assessed by means of two 24 h recalls, and a quantitative food-frequency questionnaire. Adherence to the MDP was defined according to a score constructed considering the consumption of nine MDP characteristic components: high MUFA:saturated fatty acids ratio, moderate ethanol consumption, high legumes, cereals and roots, fruits, vegetables, and fish consumption, and low consumption of meat and milk. Then, socio-demographic, lifestyle and health status variables that could determine a higher or lower adherence were assessed. Adherence to the MDP among the population of the Balearic Islands was found to be 43.1 (sd 5.8)%, and was similar in all socio-demographic and lifestyle groups, with some differences according to age, sex and physical status. There was an increase in the percentage of adherence with age, which was greater in males than in females. A more physically active lifestyle was associated with a higher adherence to the MDP. The promotion of the Mediterranean lifestyle, including the MDP and greater physical activity, should be reinforced in the population of the Balearic Islands and especially in the younger generations.     

Eating behaviours and obesity in the adult population of Spain

To examine the association between several eating behaviours and obesity, data were taken from a cross-sectional study conducted with 34,974 individuals aged 25-64 years, representative of the non-institutionalised Spanish population. Obesity was defined as BMI >or= 30 kg/m2. Study associations were summarised with OR obtained from logistic regression, with adjustment for socio-demographic and lifestyle factors. The results showed that those skipping breakfast were more likely to be obese, both in men (OR 1.58; 95 % CI 1.29, 1.93) and women (OR 1.53; 95 % CI 1.15, 2.03). Moreover, obesity was more prevalent in those having only two meals per day than in those having three or four meals in men (OR 1.63; 95 % CI 1.37, 1.95) and women (OR 1.30; 95 % CI 1.05, 1.62). Also, snacking was associated with obesity in women (OR 1.51; 95 % CI 1.17, 1.95). However, no association was observed between obesity and having one or more of the main meals away from home, in either sex. In conclusion, skipping breakfast and eating frequency were associated with obesity. The lack of association between eating away from home and obesity is in contrast to most previous research conducted in Anglo-Saxon countries. Differences in the type of establishment frequented when eating out or in the characteristics of restaurant customers in a Mediterranean population might explain these conflicting results.     

Socio-economic status and body mass index in low-income Mexican adults

The study reported here explored the associations of body mass index (BMI), socio-economic status (SES), and beverage consumption in a very low-income population. A house-to-house survey was conducted in 2003 of 12,873 Mexican adults. The sample was designed to be representative of the poorest communities in seven of Mexico's 31 states. Greater educational attainment was significantly associated with higher BMI and a greater prevalence of overweight (25 < or = BMI<30) and obesity (30 < or = BMI) in men and women. The combined prevalence of overweight and obesity was over 70% in women greater than the median age of 35.4 years with at least some primary education compared with a prevalence of 45% in women below the median age with no education. In both sexes, BMI was positively correlated with education, occupation, quality of housing conditions, household assets, and subjective social status. BMI and household income were significantly correlated in women but not in men. In the models including all SES variables, education, occupation, housing conditions and household assets all contributed independently and significantly to BMI, and household income and subjective social status did not. Increased consumption of alcoholic and carbonated sugar beverages was associated with higher SES and higher BMI. Thus, in spite of the narrow range of socio-economic variability in this population, the increased consumption of high calorie beverages may explain the positive relationship between SES and BMI. The positive associations between SES and BMI in this low-income, rural population are likely to be related to the changing patterns of food availability, food composition, consumption patterns and cultural factors. Contextually sensitive population-level interventions are critically needed to address obesity and overweight in poor populations, particularly in older women.     

Overweight/obesity is associated with food choices related to rice and beans, colors of salads, and portion size among consumers at a restaurant serving buffet-by-weight in Brazil

The present study investigated the prevalence of overweight/obesity and its relationship with behavioral and food choice characteristics among consumers at a restaurant serving buffet-by-weight in the city of Florianopolis, southern Brazil, during lunch time. An analytical cross-sectional survey of 675 consumers aged 16-81 years was conducted. The measures included anthropometric, socio-demographic, and behavioral characteristics, as well as portion size and a photographic record of the plate chosen by the consumer. The results indicated a prevalence of overweight/obesity in the sample of 33.8%. Overall, after an adjustment for other variables (sex, age, schooling, marital status, and food choice variables), overweight/obesity was positively associated with not choosing rice and beans (PR=1.11) and larger portion sizes (PR=1.08 for a portion size of 347-462g and PR=1.16 for a portion size of 463g or more). Moreover, choosing 1-2 colors of salads showed a positive association when compared with choosing 3 or more colors of salads (PR=1.06). Efforts in helping consumers make healthier food choices when eating out and thereby possibly reduce weight gain should address those aspects along with socio-demographic factors.     

Self-reported faster eating associated with higher ALT activity in middle-aged,apparently healthy Japanese women

ObjectiveFaster eating and elevated circulating activity of alanine aminotransferase (ALT), a marker for liver injury, are risk factors for the development of obesity and type 2 diabetes mellitus, and their complications. The aim of this study was to examine the association between self-reported eating rate and circulating ALT activity in apparently healthy middle-aged Japanese women.MethodsWe conducted a cross-sectional study of 900 apparently healthy women ages 40 to 64 y (mean ± SD, 53.1 ± 7.1 y) who participated in health check-ups in Japan. We analyzed their clinical serum parameters and lifestyle factors, including self-reported eating rate. Associations between liver injury markers (ALT, γ-glutamyl transpeptidase [GTP], and aspartate aminotransferase [AST]), other clinical parameters and lifestyle factors were analyzed using Tukey's multiple range test following analysis of variance and analysis of covariance for three groups, divided by self-reported eating rates. The associations between self-reported faster eating and ALT activity and lifestyle factors were analyzed by multivariate logistic regression analyses.ResultsALT activity, but not γ-GTP or AST activities, was higher in participants who reported relatively fast/very fast eating than in those who reported medium eating after adjusting for age, alcohol intake, energy intake, smoking, and physical activity. The odds ratio of eating rate for ALT activity in T3 (18-128 U/L) compared with T1 (3-12 U/L) was 1.67 (P < 0.01), but the association disappeared after adjustment for body mass index (BMI).ConclusionsALT activity is positively associated with faster eating, but is dependent on BMI in middle-aged, apparently healthy Japanese women.
