Relationship of satisfaction with body size and trying to lose weight in a national survey of overweight and obese women aged 40 and older, United States

Prevalence of poor body image and its correlation with self-esteem and depression in middle-aged women

OBJECTIVE

This study aimed to determine the prevalence and predictors of poor body image and its influence on low self-esteem and depression in middle-aged women.

METHODS

The study was a cross-sectional survey of 372 women using a predesigned online questionnaire. Main outcome measures were mean scores on the nine-point body image scale (BIS) and prevalence of poor body image (BIS ≥ 10). Significant sociodemographic, physical and mental health predictors of BIS ≥ 10 were established using logistic regression analysis. Correlation of body image with self-esteem, assessed by Rosenberg's self-esteem scale, and depression, assessed by Beck's Depression Inventory, was established using Pearson's correlation coefficient and the odds ratios were determined using logistic regression analysis.

RESULTS

The mean scores obtained for body image were 5.52 (standard deviation 4.82) and the prevalence of BIS ≥ 10 was 17.4%. Significant predictors of poor body image were education status (0.59, 95% confidence interval [CI] = 0.39-0.89), body mass index (2.26, 95% CI = 1.12-4.55), social support structure (0.35, 95% CI = 0.16-0.79), diagnosis of mental illness (3.74, 95% CI = 1.31-10.66) and perception of menopause (positive vs. negative: 0.20, 95% CI = 0.07-0.55). Body image scores correlated with self-esteem (r = -0.46; 95% CI = -0.54 to -0.38) and depression (r = 0.59; 95% CI = 0.52-0.65). BIS ≥ 10 significantly increased the odds of low self-esteem (5.71; 95% CI = 2.66-12.26) and depression (11.25; 95% CI = 4.9-27.7).

CONCLUSIONS

The prevalence of poor body image in middle-aged women was 17.4%. This strongly correlated with low self-esteem and depression. A lower education status, higher body mass index, a negative perception of menopause, poor social support structure and a history of mental health diagnosis increased the odds of poor body image prevalence in middle-aged women.

Development of Body Dissatisfaction in Women and Men at Different Educational Levels During the Life Course

BACKGROUND

Our study examines the rarely investigated associations between body dissatisfaction and educational level over the life course in women and men.

METHODS

A Finnish cohort (N = 1955) was followed by questionnaires at ages 22, 32, 42, and 52. Body dissatisfaction was measured by asking the respondents to evaluate their appearance using five response options. Analyses were done using logistic regression, while latent class analyses were used to identify classes of body dissatisfaction trajectories over the life course.

RESULTS

Body dissatisfaction increased with age in women and men. Among men, body dissatisfaction was related to lower education at the ages of 32 and 42. Also, men with lower education were more likely to maintain a less positive body image over the life course. In women, increasing body dissatisfaction during the life course was associated with lower education.

CONCLUSIONS

Differences in body dissatisfaction based on educational level are important to take into account in public health actions aiming to reduce socioeconomic inequalities in health and well-being.

The Role of Body Appreciation in the Decision to Complete Metabolic and Bariatric Surgery Among Ethnically Diverse Patients

PURPOSE

Metabolic and bariatric surgery (MBS) is an evidence-based safe, effective treatment for obesity. However, only half of referred or eligible persons complete the procedure for unknown reasons. The proposed study examined the association between the degree of body appreciation and the decision to complete MBS by ethnicity.

METHODS

This prospective cohort study included 409 participants who had been referred to a bariatric surgeon or an obesity medicine program between August 2019 and May 2022. Participants completed a survey about health behaviors and psychosocial characteristics, including body appreciation by MBS completion status (Y/N). Multivariate logistic regression models generated adjusted odd ratios (aOR) and 95% confidence intervals (CIs) of body appreciation among MBS completers vs. non-completers.

RESULTS

The sample mean age was 47.18 years (SD 11.63), 87% were female. 39.6% identified as non-Hispanic White (NHW), 38.5% as non-Hispanic Black (NHB), and 17.6% as Hispanic. Over a third of the sample (31.05%, n = 127) completed MBS. "Often" experiencing body appreciation was the most significant predictor of MBS completion (aOR: 28.19, 95% CI: 6.37-124.67, p-value < 0.001), followed by "Sometimes" (aOR: 20.47, 95% CI: 4.82-86.99, p-value < 0.001) and "Always" (aOR: 13.54, 95% CI: 2.55-71.87, p-value < 0.01) after controlling for sex, age, and race/ethnicity. There was not a significant interaction between body appreciation and race/ethnicity (p-value = 0.96).

CONCLUSION

Results showed a significant association between body appreciation and MBS completion, controlling for sex, age, and race/ethnicity. MBS clinical settings may want to assess body appreciation as a pre-operative screener among ethnically diverse patients.

20-55 Yaş Arası Kadınların Beden Algılarının Değerlendirilmesi

Amaç: Beden algısı, algılanan ile sahip olunan vücut ağırlığı arasındaki uyum olup beden algısındaki bozulmalar duygu durum bozukluğu, depresyon, yeme bozuklukları, obezite, aşırı artmış fiziksel aktivite gibi olumsuz durumlara zemin oluşturmaktadır. Çalışmanın amacı 20-55 yaş arası kadınların beden algısının ve beden memnuniyetinin değerlendirilmesidir.Yöntem: Çalışmaya 20-55 yaşları arasında 236 kadın katılmıştır. Çalışmada katılımcılardan antropometrik ölçümler, sosyodemografik özellikler ve obeziteye dair bilgi düzeyinin belirlenmesine yönelik bilgiler alınmıştır. Beden algılarının saptanması için belirli Beden Kütle İndeksi (BKİ) değerlerine sahip 1’den 6’ya kadar sıralanmış kimliksiz silüetler katılımcılar tarafından kişilik, sağlık, sosyal özelliklerine göre değerlendirilmiştir.Bulgular: Araştırmaya katılan kadınların %65,3’ünde beden ağırlığı memnuniyetsizliği olduğu; memnun olmayanların %92,2’sinin ise ağırlık kaybetmek istedikleri gözlemlenmiştir. Katılımcılar düşük BKİ’ye sahip silüetleri kişilik, sosyal, sağlık yönünden daha olumlu özellikler ile eşleştirmiştir. Beden memnuniyetsizliğinin ve bozuk beden ağırlığı algısının artan BKİ, yaş, kronik hastalık durumu ile anlamlı bir biçimde ilişkili olduğu; eğitim düzeyi, meslek grubu, fiziksel aktivite düzeyi, obeziteye dair bilgi düzeyi ile anlamlı bir ilişkisi olmadığı saptanmıştır.Sonuç: Kadınların çoğunda bozuk beden algısı olduğu daha ince bir vücut görünümünü idealleştirdikleri, hafif şişman silüetleri obez olarak niteledikleri tespit edilmiştir. 

Factors Associated with Weight Loss Maintenance and Weight Regain Among African American and White Adults Initially Successful at Weight Loss

BACKGROUND

Providing ongoing treatment through extended care programs can improve weight loss maintenance (WLM), but the effectiveness of these programs for African Americans (AA) are mixed and may be due to unique cultural factors.

PURPOSE

To identify, prioritize, and organize factors associated with WLM as experienced by AA and White adults initially successful with weight loss.

METHODS

Adults identified their greatest amount of lifetime weight loss, and those achieving ≥5% weight loss were classified as maintainers (continued >5% weight reduction for ≥1 year) or regainers (≤5% weight reduction) based on current weight. The nominal group technique was conducted to identify and rank WLM facilitators and barriers. Online card sorting tasks and hierarchical clustering were performed to illustrate conceptual relationships between facilitators (maintainers only) and barriers (regainers only).

RESULTS

Participants (maintainers, n = 46; regainers, n = 58; 81.7% women, 48.1% AA) identified known factors associated with successful weight management (daily weighing, self-monitoring, regular physical activity, mindful eating). However, the perceived importance of these factors differed between groups (maintainer vs. regainers; AA vs. Whites). Unique factors affecting WLM were also identified (refresher groups recommended by White maintainers and regainers; self-accountability identified by AA maintainers). Salient facilitators and barriers were best represented in 2-3 clusters; each group had ≥1 unique cluster(s) revealing group-specific higher-order domains associated with successful WLM.

CONCLUSIONS

As lifestyle interventions for WLM (particularly for AA) are developed, attention to the preferences, and lived experiences of these groups is recommended. Strategies targeting physical activity maintenance and autonomy-supportive approaches may improve WLM among AA.

Perceptions of body weight that vary by body mass index: Clear associations with perceptions based on personal control and responsibility

This project aimed to identify the perceptions of body weight that vary by body mass index. First, a qualitative study explored body weight perceptions in 17 individuals with overweight. Second, a questionnaire was developed and completed by a UK sample with body mass index from 16.6 to 59.7 kg/m2 (N = 328). A higher body mass index was associated with perceptions of less personal control and responsibility. Body mass index in females was also associated with three other questionnaire factors and body mass index in males with illness/medication. Thus, body mass index was associated with different perceptions of body weight. Focussing on personal control and responsibility may be useful for treatment and prevention.

Individual and Family Factors in Disordered Eating Patterns of Mexican-American Women

OBJECTIVE

In this study, we examined the contribution of individual- (acculturation, body mass index, and body size satisfaction) and family- (maternal weight-related messages and disordered eating patterns) level factors in predicting bulimic and dieting behaviors in young Mexican-American women with overweight or obesity.

METHODS

We recruited adult Mexican- American mother-daughter dyads from the community. We conducted correlational analysis and hierarchical regression.

RESULTS

Daughters who were less satisfied with their body size reported higher symptoms of bulimic (r = -.34, p < .01) or dieting behavior (r = -.36, p < .01). Daughters who received more positive maternal messages on eating and weight had mothers with lower symptoms of bulimic (r = -.43, p < .01) or dieting behavior (r = -.30, p < .05). Maternal symptoms of bulimic behavior were the strongest predictor of daughters' bulimic behavior (ß = .379, p = .007), and body size satisfaction was the strongest predictor of daughters' dieting behavior (ß = -.372, p = .008) in adjusted models.

CONCLUSION

Mexican-American women who are less satisfied with their body size and have mothers with elevated symptoms of bulimic behavior are at risk for disordered eating patterns. Intervening at the individual level on body image and family level on maternal modeling of eating behavior may help support healthy weight management behaviors.

Is a 'culture of plus-size women' the independent effect of neighborhood disadvantage on female BMI? A cross-sectional study in two Chilean Municipalities

Research has shown that neighborhood disadvantage has an effect on BMI that is independent of individual disadvantage, much more pronounced in women than in men. The mechanisms that explain this gender-specific effect are not yet clear. Since women's body size dissatisfaction is closely linked to gender differences in BMI inequalities, the independent effect of neighborhood disadvantage on female BMI may relate to a local culture of acceptance of female large bodies, that could influence women's parameters for body size dissatisfaction. This study explored how the relation between female BMI, neighborhood income, individual income and education is influenced by body size dissatisfaction in a random sample of 882 women aged 20-60 that reside in two Chilean Municipalities. Data have a two level structure (women nested in 17 neighborhoods); it was collected by direct survey, height and weight were measured with portable instruments. Disadvantaged neighborhoods house mainly poor and low educated women, whereas the wealthier ones were inhabited mostly by affluent women with postsecondary education. The proportion of women without a husband/partner and with more than three children in disadvantaged neighborhoods was higher than better off areas. Multilevel linear regression showed that neighborhood disadvantage had an effect on female BMI that was independent of women's income and education, which was explained by body size dissatisfaction. The mean BMI for body size satisfaction among women in disadvantaged neighborhoods was 2 kg/m² higher than in affluent areas, which suggests that a 'culture of plus-size women' would emerge in urban clusters of poverty. The findings signal that neighborhood effects on BMI would relate to the socioeconomic polarization of urban areas, with marked concentrations of poverty and wealth, and might be explained by the psychosocial pathways associated to social disadvantage that act in addition to the effects of material conditions to influence people's health.

Body size perception, knowledge about obesity and factors associated with lifestyle change among patients, health care professionals and public health experts

Background

The attitudes towards obesity may have an important role on healthier behavior. The goal of the present study was to explore the attitudes towards obesity and to investigate how these attitudes were associated with lifestyle-changing behavior among the patients attending primary care centers, health care professionals and public health experts.

Methods

This cross-sectional survey study was performed in 10 primary care offices in different regions in Lithuania and in 2 public health institutions. Nine hundred thirty-four patients, 97 nurses, 65 physicians and 30 public health experts have filled the questionnaire about attitudes towards obesity and presented data about lifestyle-changing activities during last 12 months. The attitudes were compared between different respondent groups and factors associated with healthier behaviors were analyzed among overweight/obese individuals in our study population.

Results

Participants failed to visually recognize correct figure corresponding to male and female with obesity. Majority of respondents’ perceived obesity as a risk factor for heart diseases and diabetes but had less knowledge about other diseases associated with weight. About one third of respondents changed their lifestyle during last 12 months. Overweight individuals with age < 45 years (OR 1.64, 1.06–2.55; p = 0.025) were more likely and those who overestimated current weight (OR 0.44, 0.20–0.96; p = 0.036) less likely to change their lifestyle. Disappointment with their current weight (OR 2.57, 1.36–4.84; p = 0.003) was associated with healthier behavior among participants with obesity.

Conclusion

Participants had similar body size perception and knowledge about obesity. Younger age had significant association with lifestyle changing behavior among overweight individuals and disappointment with current weight among obese participants.

Associations of Body Dissatisfaction With Lifestyle Behaviors and Socio-Demographic Factors Among Saudi Females Attending Fitness Centers

OBJECTIVE

To examine body image perception and the associations of body dissatisfaction (BD) with socio-demographic and lifestyle factors among Saudi women attending fitness centers in Riyadh.

METHODS

Saudi females aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using stratified clustered sampling technique (n = 460). Height and weight were measured to calculate actual body mass index (BMI). A previously validated instrument was used to collect socio-demographic and lifestyle variables including physical activity (PA), sedentary behaviors, sleep and dietary habits. Stunkard Figure Rating Scale silhouettes were used to assess perceived and desired body shape.

RESULTS

The participants had a mean (SD) age of 29.2 (8.2). The majority were not married (57%), with no children (66%) and had college degrees (78%). While 63% were overweight or obese, nearly 40% of women underestimated their perceived body shape. The majority of respondents (87%) were dissatisfied with their body shape including 68% of normal weight women. Females who had BD were significantly older, had higher BMI, reported more weight loss attempt and had expended less time in vigorous (p = 0.033) and total (p = 0.042) PA than those who were satisfied with their body shape. However, when adjusting for socio-demographic variables, logistic regression analysis revealed significant associations of BD with higher BMI, shorter membership duration of fitness club, and reduced dairy products and energy drinks consumption.

CONCLUSION

Except for BMI and decreased dairy products and energy drinks consumption, many lifestyle behaviors did not associate with BD among Saudi females attending fitness centers. The findings can inform healthcare providers when intervention strategy is implicated for females with BD. Future studies should compare the associations of BD with lifestyle behaviors between males and females attending fitness centers and seeking weight loss.

The Gender-specific Role of Body Weight for Health, Earnings and Life Satisfaction in Piecewise and Simultaneous Equations Models

Based on the German Socio-Economic Panel, the correlation between the body mass index, health, earnings and life satisfaction is analysed by gender. The previous literature has found no consistent results. This might have several reasons. The purpose of this paper is to analyse the gender-specific role of weight in single equation, piecewise and simultaneous equations models. We ask whether this distinction is important for the degree of association between health, earnings, satisfaction and body weight. In our context, piecewise modelling means a separate inspection of weight coefficients for under- and overweight people, allowing the detection of non-linear influences. As a benchmark, we begin our estimations under the assumption that the association between health, earnings, satisfaction, and weight is the same for under- and overweight people, and that there are no jointly dependent influences between our three outcome variables. The basic results are: health worsens, income declines and satisfaction is poorer with higher body mass index. If the association with weight is separately determined for over- and underweight people, the estimates show striking differences between overweight men and women. Underweight women earn more and overweight less than others. For normal-weight men the income is on average higher than for over- and underweight men but this difference is insignificant. When matching and instrumental variables procedures are applied, the health outcome for overweight people matches that of independent and unmatched estimates. Stronger positive effects on health are found for underweight women. No clear-cut advantages in income of overweight women can be found. Underweight women and especially underweight men tend to be less happy. For overweight men this influence is ambiguous but more speaks in favour of a lesser level of satisfaction. Overweight women seem to be happier.

The Association of Body Image With Anthropometric Measures and Eating Disorders Among Students From University Sports Teams

Background and aims: Body image is defined as a complex concept involving a person’s thoughts, feelings, and attitudes about his/her body. The body image dissatisfaction may expose the individuals, specifically athletes, to eating disorders (EDs). The aim of this study is to assess the association of body image score with EDs and anthropometric measures in students from university sports teams. Methods: This cross-sectional study was carried out on 225 students from sports teams of Qazvin University in 2014. The samples were selected by the census method. The Multidimensional BodySelf Relations Questionnaire (MBSRQ), eating attitudes test (EAT-26) questionnaire, and demographic information questionnaire were used for collecting data. Anthropometric characteristics were also measured. The data were analyzed in SPSS software version 22.0. Results: The result of the study showed that the association of body image score with age (P=0.012, OR=0.80, CI=0.179, 1.437) and waist-to-height ratio (WHtR) (P=0.013, OR=-52.14, CI=-93.20, -11.08) was positively significant. Although the mean body image score was lower in students with EDs, it was not statistically significant. In addition, there was not a significant association between body image score and other variables such as marital status, gender, educational level, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and hip circumference (HC) (P>0.05). Conclusion: In this study, the body image had a positive significant association with age, and a negative significant one with WHtR. This may indicate that abdominal obesity plays an important role in body image satisfaction among students from the university sports teams.

Self-Report Dieters: Who Are They?

Dieting attempts have become popular worldwide. Dieting, however, seems to have both positive and negative health-related consequences. So far, only a few studies have focused on the determinants of dieting in detail. This study explores the association between self-report dieting attempts and intentional weight loss (IWL) during the previous year and several demographic, lifestyle, health, and psychological factors in a cross-sectional study design using data from the representative Finnish Health 2000 Survey. The sample comprised 2147 men and 2378 women, aged 30–69. Information for potential determinants was assembled via health examinations, interviews, and questionnaires. Approximately 24% of the men and 39% of the women reported dieting attempts and 10% of the men and 15% of the women reported IWL. Dieting attempts were associated with younger age, education, BMI, formerly smoking, more favourable values in lifestyle variables, and unfavorable values in serum HDL and triglycerides, a worse sense of coherence, concerns about one’s appearance, and concerns about one’s health. Among men, diabetics and those sleeping ≤6 h a night more frequently reported dieting attempts and those with osteoarthritis reported IWL. Moreover, the gradient between BMI and dieting attempts was significantly stronger in men than in women. Men seem to attempt dieting when they have actual health-related reasons, while such reasons are not so strongly associated with dieting in women. These findings can be used for determining subpopulations with obesity and real weight-loss needs and, alternatively, subpopulations with normal weight unnecessarily attempting dieting.

Maladaptive schemas and psychological well-being in premenopausal and postmenopausal women

INTRODUCTION

Menopause as an important event during women's life has serious effects on their mental health. This study was carried out to investigate the relationship between early maladaptive schemas and psychological well-being in postmenopausal and premenopausal women.

MATERIAL AND METHODS

The research method was descriptive-correlative. The population of this study included menopausal and premenopausal women who were referred to five community centers in district 9 in Tehran in the spring of 2018. The statistical sample comprised 282 (45-55 years old) women who were divided into 142 postmenopausal and 140 premenopausal women selected through accessible sampling. In this study two questionnaires were filled out by sample groups: the Young Schema Questionnaire (2003) and Ryff's Scales of Psychological Well-being (1989) were applied. Spearman correlation test and multiple regression analysis were employed in order to analyze hypotheses of this study.

RESULTS

The results indicated that the collection of schemas which were aimed at predicting psychological well-being in menopausal and premenopausal women were different (p ≤ 0.01). In premenopausal women isolationism, vulnerability, and subjugation schemas, and in postmenopausal women defectiveness/shame, isolationism, dependency, self-control, and approval-seeking schemas predicted psychological well-being.

CONCLUSIONS

Menopause can activate some passive schemas, and psychologists through making women aware of these change and using appropriate interventions can prevent a decrease well-being in them.

Weight perception and perceived attractiveness associated with self-rated health in young adults

Self-rated health (SRH) is a widely used and valid marker of overall health and wellbeing and demographic differences in SRH are well-established. To date, few studies have examined how multiple components of body image shape young adults' SRH. The purpose of this study was to investigate the contributions of weight perception and perceived attractiveness on SRH among young adults. Data were from Wave IV (2007-2008) of the National Longitudinal Study of Adolescent to Adult Health (Add Health) and young women and men ages 24-34 were analyzed (n = 7044 women, n = 6594 men) in April 2018. All analyses were weighted and stratified by gender. Design-based F test and ordinal multinomial logistic regression were used. For both genders, relative to Whites, Hispanic, Black, and Asian young adults reported poorer health; women and men with higher education and income reported better health. Independent of measured body mass index (BMI), young adults who thought they were underweight or overweight reported poorer health relative to those who thought their weight was normal. Both young women and young men who thought they were more attractive also reported better health. This study demonstrates that weight status, perceived weight status, and perceived attractiveness independently impact SRH for both young men and women controlling for race/ethnicity, nativity status, marital status, education, income, and number of health conditions.

Homicides, Public Goods, and Population Health in the Context of High Urban Violence Rates in Cali, Colombia

Obesity and frequent mental and physical distress are often associated with major health problems. The characteristics of the urban environment, such as homicide rates and public goods provision, play an important role in influencing participation in physical activity and in overall mental health. This study aimed to determine whether there was a relationship between homicide rates and public goods provision on the health outcomes of the citizens of Cali, Colombia, a city known for its high urban violence rate and low municipal investment in public goods. We used a linear probability model to relate homicide rates and public goods provision (lighted parks, effective public space per inhabitant, and bus stations) at the district level to health outcomes (obesity and frequent mental and physical distress). Individual data were obtained from the 2014 CaliBRANDO survey, and urban context characteristics were obtained from official government statistics. After controlling for individual covariates, results showed that homicide rates were a risk factor in all examined outcomes. An increase in 1.0 m2 of public space per inhabitant reduced the probability of an individual being obese or overweight by 0.2% (95% confidence interval (CI) = - 0.004 to - 0.001) and the probability of frequent physical distress by 0.1% (95% CI = - 0.002 to - 0.001). On average, the presence of one additional bus station increased the probability of being obese or overweight by 1.1%, the probability of frequent mental distress by 0.3% (95% CI = 0.001-0.004), and the probability of frequent physical distress by 0.02% (95% CI = 0.000-0.003). Living in districts with adequate public space and lighted parks lowers the probability of being obese and high homicide rates, which are correlated with poor health outcomes in Cali, Colombia. Investments in public goods provision and urban safety to reduce obesity rates may contribute to a better quality of life for the population.

Support needs of patients with obesity in primary care: a practice-list survey

BACKGROUND

UK guidelines recommend that patients with obesity in primary care receive opportunistic weight loss advice from health care professionals, but there is a lack of research into the characteristics and existing weight management practices of these patients. The aim of this study was to characterise primary care patients with obesity in England, to inform the screening, support, and referral options appropriate to this group.

METHODS

We surveyed 1309 patients registered at 15 GP practices in North East England, aged ≥18 years and with objectively recorded obesity (BMI ≥ 30 kg/m2). Study participants reported their weight history, health status, past and current weight loss activities, motivating factors, weight loss strategies used, professional support received, and perceived barriers to weight loss.

RESULTS

62% of participants were actively trying to lose weight, and a further 15% had attempted and discontinued weight loss in the last 12 months. Only 20% of the sample had sought GP support for weight loss in the last 12 months; instead, most efforts to lose weight were self-guided and did not use evidence-based strategies. Those who sought GP weight loss support were likely to use it and find it motivating. Participants had attempted weight loss on multiple previous occasions and overall felt less confident and successful at maintaining weight loss than losing it. Participants at greatest clinical risk (higher BMI and more health conditions) reported particularly low confidence and multiple barriers to weight loss, but were nevertheless highly motivated to lose weight and keep it off.

CONCLUSIONS

We identified the need for informational, structural, and weight loss maintenance-specific support for GP patients with objectively-recorded obesity. Study participants were motivated to lose weight and keep it off, but lacked the confidence and understanding of effective strategies required to do this. GP weight loss support was acceptable and useful but underutilised, indicating that screening and brief referral interventions to structured programmes may augment patients' current weight management activities and meet key support needs whilst optimising limited primary care resources.

Weight Perceptions and Weight-Related Behaviors among Low Income Postpartum Women

Background

Minority and low-income women have higher rates of postpartum weight retention, contributing to increased rates of obesity in these populations. Weight perceptions may be an important factor contributing to the adoption of weight-management behaviors. The purpose of this study was to examine the relationships between weight perceptions and weight-related behaviors among overweight low-income women during postpartum enrolled in a weight loss intervention study.

Methods

This is a cross-sectional analysis of the Fresh Start study baseline data among overweight and obese low-income women during postpartum (N = 132). General linear regression models assessed the association between weight perceptions and energy intake, energy expenditure, self-monitoring, and self-regulation.

Results

Women who perceived themselves to be very overweight had significantly lower self-regulation (β = -4.0, SE = 1.6, p = 0.014) and higher energy expenditure (β = 1.3, SE = 0.7, p = 0.05) compared to women who perceived themselves to be moderately overweight or a little overweight. There were no significant associations between weight perceptions and self-monitoring or energy intake.

Conclusions

This study found that weight perceptions among these women are important factors to consider for weight loss. Future research should focus on investigating the impact of tailoring interventions to weight perceptions to impact engagement in weight-related behaviors in diverse low-income women during postpartum.

Racial Differences in Weight Gain: A 5-Year Longitudinal Study of Persons With Spinal Cord Injury

OBJECTIVE

To assess racial differences in body mass index (BMI) change over 5 years among people with spinal cord injury (SCI).

DESIGN

Multicenter longitudinal study.

SETTING

Spinal Cord Injury Model Systems centers.

PARTICIPANTS

Individuals (N=437; 313 non-Hispanic white, 81 non-Hispanic black, and 43 Hispanic; 335 men; mean age, 41.3±13.5y) who incurred an SCI from 1974 to 2010 and completed 2 follow-up assessments within 5 years between October 1, 2006 and September 18, 2015 (mean duration of injury, 9.1±9.6y at the start of the 5-year follow-up).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

BMI (in kilograms per meters squared).

RESULTS

The mean BMI of 437 participants increased from 26.4±6.3 to 27.0±6.4kg/m² over 5 years (P=.002). The greatest increase was noted for Hispanics (2.0±5.7kg/m²; P=.02), followed by non-Hispanic whites (0.6±3.9kg/m²; P=.01) and non-Hispanic blacks (0.01±3.7kg/m²; P>.99). The differences in BMI increase across racial groups were significant (P=.03) in those with paraplegia (American Spinal Injury Association Impairment Scale A, B or C), those who were underweight or of normal weight at baseline, and those within 10 years of their injury. Such racial differences remained significant after taking into account demographic and injury characteristics.

CONCLUSIONS

Our study findings provide a foundation for future research to explore risk and protective factors that contribute to racial differences in weight gain after SCI, which help alert health care professionals to a high-risk group for obesity prevention and management.

Associations between complementary medicine, satisfaction with body weight and shape, and the use of methods to lose or control weight: Results of a national survey of 8009 Australian women

OBJECTIVE

This study aimed to determine whether the use of complementary medicine (CM) is associated with body satisfaction and weight management methods in Australian women.

METHODS

Women aged 34-39 years from the Australian Longitudinal Study on Women's Health were surveyed regarding satisfaction with their body weight and shape, and the use of weight management methods. Associations with CM use were analysed using logistic regression modelling.

RESULTS

Women using CM less likely wanted to lose weight; and were more likely to cut down on fats and/or sugars, use low glycaemic diets, diet books and 'other' methods (OR: 1.33-2.83) compared to CM non-users. Women using herbal medicine products 'sometimes' were more likely to use meal replacements/slimming products (OR: 1.50-1.67) compared to non-users.

DISCUSSION

Australian women using CM are more likely to be satisfied with their body weight and shape, and to use a range of weight management approaches compared to CM non-users.

Do Black Women's Religious Beliefs About Body Image Influence Their Confidence in Their Ability to Lose Weight?

INTRODUCTION

Black women are disproportionately burdened by obesity but maintain body satisfaction and strong religious commitment. Although faith-based weight-loss interventions have been effective at promoting weight loss among blacks, little is known about how body image and religious views contribute to weight-related beliefs among religious black women. The purpose of this study was to examine whether demographic and health history factors, religious involvement, and beliefs about body image could explain motivation and confidence to lose weight among a church-affiliated sample of black women.

METHODS

We recruited 240 church-affiliated black women aged 18 to 80 years (average age, 55 y; SD, 12.3) in 2014 from 6 black churches that participated in a larger study, Project FIT (Faith Influencing Transformation), a clustered, diabetes/heart disease/stroke intervention among black women and men. We used baseline data from Project FIT to conduct a cross-sectional study consisting of a survey. Variables approaching significance in preliminary correlation and χ² analyses were included in 2 multiple linear regression models examining motivation and confidence in ability to lose weight.

RESULTS

In final regression models, body mass index was associated with motivation to lose weight (β = 0.283, P < .001), and beliefs about body image in relation to God predicted confidence to lose weight (β = 0.180, P = .01).

CONCLUSION

Faith-based, weight-loss interventions targeting black women should emphasize physical well-being and highlight the health benefits of weight management rather than the benefits of altering physical appearance and should promote positive beliefs about body image, particularly relating to God.

Body Weight Misperception and Dissatisfaction Among Overweight and Obese Adult Nigerians

BACKGROUND

The increase in the prevalence of overweight and obesity in low- and medium-income countries has a negative impact on overall health. Correct perception of one's body weight is a step in seeking healthy help toward weight reduction in overweight and obese individuals.

OBJECTIVE

This study was carried out to assess the body weight misperception and dissatisfaction among overweight and obese adults in an urban African setting.

METHODS

This study was part of a larger cross-sectional study that was designed to plan an intervention for overweight and obese adults in an urban African setting. For this study, we randomly selected only overweight and obese adults (≥18 years old) who consented to participate in the study from 15 enumeration areas in Alimosho Local Government Area of Lagos State, Nigeria. We followed the World Health Organization guidelines for conducting community surveys in recruiting overweight and obese participants. We assessed body weight perception and dissatisfaction through their responses to the following: "How do you describe your weight?" and "I feel bad about myself because of my weight." Data for this study were collected between November 2012 and March 2013.

RESULTS

We recruited 567 participants, of whom more than half (n=304, 53.6%) misperceived their weight as either underweight or normal weight, and 61.2% (n=186) of whom were women. The strength of agreement between the actual body mass index and weight perception was very poor (κ=.032, SE .015, P=.04). The strongest predictor of weight perception was sex (female) with an odds ratio of 1.63 (95% CI 1.13-2.35). About 41.1% (n=233) of the participants were dissatisfied with their weight, of whom 30.0% (n=70) were men. Age (young adult) was a predictor of weight dissatisfaction with an odds ratio of 2.37 (95% CI 1.62-3.46).

CONCLUSIONS

More than half of the participants misperceived their body weight as either underweight or normal weight, and the majority of them were women. More men were not happy with their body weight, and participants in the young adult age group were more dissatisfied with their body weight.

A pilot study of body image perceptions, and attitudes toward obesity in hospitalized psychotic and non-psychotic patients

OBJECTIVE

Body image perceptions, and attitudes toward obesity were examined and compared between psychotic and non-psychotic patients with a mood disorder.

METHODS

80 psychotic patients and 36 non-psychotic patients with a mood disorder admitted to an acute inpatient psychiatric unit participated in the study. On admission, each patient completed a visual silhouettes scale of actual self and ideal self, as well as the Attitudes Toward Obese Persons (ATOP) scale.

RESULTS

Analogous to the general population, psychotic and non-psychotic patients had similar body image perceptions, and experienced discrepancy between actual and ideal body image. Female patients with serious mental illness (SMI) picked a heavier actual self body image, and experienced greater discrepancy between actual and ideal body image compared to male patients with SMI. Psychotic and non-psychotic patients experienced similar mostly neutral attitudes toward obese persons, however there was a trend for depressed patients to have more negative attitudes toward obese persons compared to non-depressed patients.

DISCUSSION

The presence of an acute psychotic episode did not affect body perceptions, or obesity attitudes; however depressed patients had more negative obesity attitudes. Similar to the general population, females with SMI overassessed their body size, and experienced more body dissatisfaction compared to males with SMI.

Association of weight control behaviors with body mass index and weight-based self-evaluation

Objective:

To determine the frequency of weight control behaviors (WCBs) and their correlation with body mass index (BMI) and weight-based self-evaluation.

Methods:

Data were collected by the Brazilian Internet Study on Temperament and Psychopathology (BRAINSTEP) from 27,501 volunteers (30.4% men, mean age 28.9±8.7 years).

Results:

The most prevalent WCBs for men and women were exhaustive physical exercise and prolonged fasting, respectively. Frequent exhaustive physical exercise was the only behavior more often adopted by men. BMI was positively associated with WCBs, which were very frequent in obese subjects. About 15% of normal-weight women reported using diuretics and laxatives, and 12.2% reported vomiting as a WCB at least occasionally. Among subjects who regarded body weight highly in their self-evaluation, there was a strong positive association with all WCBs, at similar degrees, in both genders. Compared to those who never base their intrinsic personal value on body weight, those who frequently base intrinsic value on body weight were at 25-30 times higher risk of inducing vomiting.

Conclusion:

The prevalence of participants adopting WCBs was high, especially in women and obese subjects. Weight-based self-evaluation was more strongly associated with WCBs than BMI.

Racial/Ethnic Differences in Weight-Loss Strategies among US Adults: National Health and Nutrition Examination Survey 2007-2012

BACKGROUND

Dieting, exercising, and seeking professional help have been associated with intentional weight loss among adults.

OBJECTIVE

This study examined the use of diet (eg, ate less, ate less fat, or switched to low-calorie foods), exercise, diet and exercise, and professional help (eg, weight-loss program or prescribed diet pills) for weight loss among non-Hispanic whites, Mexican Americans, and non-Hispanic blacks.

DESIGN

Cross-sectional data from the 2007-2012 National Health and Nutrition Examination Survey were used.

PARTICIPANTS

Males and females (n=9,046) aged 20 to 65 years were included.

MAIN OUTCOME MEASURE

The weight history questionnaire assessed weight-loss attempts and use of weight-loss strategies in the past year.

STATISTICAL ANALYSES PERFORMED

Multivariate logistic regression models were used to estimate associations of race/ethnicity with strategies to lose weight. Models controlled for age, sex, education, and body mass index. In fully adjusted models, interactions of race/ethnicity by sex were tested.

RESULTS

Lower proportions of Mexican Americans (35%) and non-Hispanic blacks (35%) than non-Hispanic whites (39%) reported trying to lose weight. Among those who tried to lose weight, non-Hispanic blacks were less likely than non-Hispanic whites to use diet (odds ratio [OR] 0.78, 95% CI 0.67 to 0.90) or exercise (OR 0.83, 95% CI 0.70 to 0.99) for weight loss. Mexican Americans (OR 0.71, 95% CI 0.53 to 0.95) and non-Hispanic blacks (OR 0.71, 95% CI 0.52 to 0.95) were also less likely than non-Hispanic whites to use professional help for weight loss. The relationships between race/ethnicity and weight-loss strategy were stronger for females than males.

CONCLUSIONS

Targeted efforts are needed to address racial/ethnic disparities in weight-loss attempts and use of recommended strategies especially among females.

Relationship Among Body Image, Anthropometric Parameters and Mental Health in Physical Education Students

Background

The prevalence of body image dissatisfaction (BID) is currently high. Given that psychological well-being is associated with the body measurements imposed by esthetic standards, BID is an important risk factor for mental disorders.

Objective

Identify the prevalence of BID, and compare anthropometric and mental health parameters between individuals satisfied and dissatisfied with their body image.

Method

A total of 140 university students completed the silhouette scale to screen for BID. Anthropometric measures, body mass index (BMI), waist circumference (WC) and body fat percentage (BFP) were used. To investigate mental health, The State-Trait Anxiety Inventories (STAI-S and STAI-T), Profile of Mood States (POMS) scale and Quality of Life (QOL-36) questionnaire were used to investigate mental health. The Student’s t-test was applied to compare anthropometric and mental health parameters.

Results

67.1% of university students exhibited BID. There was a significant difference (p = 0.041) in BF and WC (p = 0.048) between dissatisfied and satisfied individuals. With respect to mood states, significant differences were observed for anger (p = 0.014), depression (p = 0.011), hostility (p = 0.006), fatigue (p = 0.013), mental confusion (p = 0.021) and total mood disturbance (TMD) (p = 0.001). The mental aspect of QOL was significantly higher (p = 0.001) in satisfied university students compared to their dissatisfied counterparts.

Conclusion

BID was high and it seems to be influenced by anthropometric measures related to the amount and distribution of body fat. This dissatisfaction may have a negative effect on the quality of life and mood state of young adults.

Body image satisfaction and weight concerns among a Mediterranean adult population

Background

People tend to underestimate their current weight and overestimate their height minimizing health risk factors. The aim of this study was to assess body weight satisfaction, acceptance of body image, weight concern and dieting habits among a Mediterranean adult population.

Methods

Cross-sectional survey was carried out (2009–2010) in the Balearic Islands, Spain. A random sample (n = 1081) of young (18–35 y.o.) and middle-aged adults (36–55 y.o.) was interviewed and anthropometrically measured.

Results

Women were more dissatisfied being overweight, less dissatisfied being underweight, and more worried about weight gain than men. Middle-aged participants were more dissatisfied with body shape and underestimated body weight than young’s. Employed women defined better current weight than unemployed, but unemployed were more worried about body weight gain. Overweight adults were more likely to underestimate their body weight but were also very worried about weight gain and more likely to report current dieting than their leaner counterparts. Active participants self-reported better body weight and were more satisfied with body image than sedentary.

Conclusions

Most of studied population reported body image dissatisfaction, but half of them are not worried about it. Women were more concerned about their body weight status. Practice of physical activity is a positive factor in self-perception. Holistic strategies are needed to avoid promoting unreal bodies, as well as the acceptance of the real body image.

Prevalence of personal weight control attempts in adults: a systematic review and meta-analysis

The purpose of this systematic review and meta-analysis was to estimate the prevalence of personal weight control attempts (weight loss and/or maintenance) worldwide and to identify correlates, personal strategies used and the underlying motives. We included epidemiological/observational studies of adults (≥18 years) reporting prevalence of weight control attempts in the past-year. Seventy-two studies (n = 1,184,942) met eligibility criteria. Results from high quality studies showed that 42% of adults from general populations and 44% of adults from ethnic-minority populations reported trying to lose weight, and 23% of adults from general populations reported trying to maintain weight annually. In general population studies, higher prevalence of weight loss attempts was observed in the decade of 2000-2009 (48.2%), in Europe/Central Asia (61.3%) and in overweight/obese individuals and in women (p < 0.01). Of the 37 strategies (grouped in 10 domains of the Oxford Food and Activity Behaviours Taxonomy) and 12 motives reported for trying to control weight, exercising and dieting (within the energy compensation and restraint domains, respectively) and wellbeing and long-term health were the most prevalent. To our knowledge, this is the first systematic review to investigate weight control attempts worldwide. Key strategies and motives were identified which have implications for future public health initiatives on weight control.

Predictors of Fat Intake Behavior Differ between Normal-Weight and Obese WIC Mothers

Purpose.

To determine whether predictors of fat intake behavior were the same for normal-weight and obese WIC mothers when applying the PRECEDE-PROCEED model and to identify predictors for each group.

Design.

Proportional stratified convenience sampling.

Subjects.

Five hundred eighty-one nonpregnant, black and white normal-weight (n = 180) or obese (n = 401) women.

Settings.

The Special Supplemental Nutrition Program for Women, Infants and Children in six counties in southern Wisconsin.

Measures.

The independent variables were predisposing, enabling, and reinforcing factors. Predisposing factors included beliefs in diet and health, beliefs in diet and body shape, health concerns in food choice, health concerns in nutrition, and eating habits. Enabling factors were cost of food, availability of time to prepare food, and accessibility to purchase food. Reinforcing factors were weight control intentions, sensory appeal, and mood. The dependent variable was fat intake behavior. Structural equation modeling was performed.

Results.

When controlling for covariates, certain factors affecting fat intake behavior differed between the normal-weight and the obese groups. For the normal-weight group, only reinforcing factors were positively associated with fat intake behavior. For the obese group, reinforcing and enabling, but not predisposing, factors were positively associated with fat intake behavior.

Conclusions.

Interventions to modify low-income women's fat intake behavior might benefit from targeting behavioral predictors that differ with body size. Messages that emphasize weight control intentions, sensory appeal, and mood are likely to affect both normal-weight and obese women. Information about cost of food, availability of time to prepare food, and accessibility to purchase food is likely to be more effective with obese women.

Changes in Obesity Prevalence Among Women Aged 50 Years and Older

Obesity is an important public health issue facing Americans of all ages. Behavioral Risk Factor Surveillance System data are used to illustrate the change in body mass index distribution in just one decade (1990-2000) in women aged = 50. The sample size ranged from 18,474women = 50 in 1990 to 45,820 in 2000. Forwomen aged = 50, there is a slight decline in the prevalence of underweight (from 3.1% in 1990 to 2.4% in 2000) and a significant increase in obesity (from 14.4% to 21.7%). Not smoking, having less education, being in poor health, having diabetes, and not exercising are all associated with increased odds of being obese. Although factors significantly related to obesity in older women are consistent with those previously identified in younger women, the weight group distributions in olderwomen differ. The physical and social influences of age and gender need to be incorporated into health promotion programs.

Body Image Satisfaction Among Blacks

Satisfaction with body image is a factor related to health outcomes. The purpose of this study is to examine the relationship between body image satisfaction and body size perception in an urban, Black community sample in New Orleans, Louisiana. Only 42.2% of respondents were satisfied with their body image and 44.1% correctly perceived their body size. Most respondents chose an ideal image in the normal body mass index range with over half choosing an ideal image smaller than their actual size. Misperception was greatest among the heaviest respondents. Females, those who overestimated their size, those with an education beyond high school, and those who were active in order to lose weight were less likely to be satisfied ( p < .001). Those who were active but not trying to lose weight were more likely to be satisfied ( p < .001). This suggests that perception of and satisfaction with body size may play a role in health behavior decisions.

Characteristics of patients potentially eligible for pharmacotherapy for weight loss in primary care practice in the United States

Objective

To describe the characteristics of real‐world patients potentially eligible for adjunctive pharmacotherapy for weight loss.

Methods

Patients from the GE Centricity electronic medical record database were selected if they had body mass index (BMI) ≥30 or ≥27 to <30 kg m⁻² with ≥1 obesity‐associated comorbidity (hypertension, dyslipidemia, or type 2 diabetes) from 2002–2011; were aged ≥18 years and had ≥12 months of continuous enrollment before and after the date of first eligible BMI recorded (index date). Descriptive statistics and logistic regression were used for analysis.

Results

Of the 1,835,541 patients with overweight or obesity included, comorbidities were common (hypertension [55.4%], dyslipidemia [36.1%] and type 2 diabetes [13.4%]). The percentage of patients who received pharmacotherapy for weight loss was 0.7% within 12 months after the index date. Patients who received pharmacotherapy had higher BMI (median, 33.6 vs. 31.3 kg m⁻²), were younger (median, 42 vs. 52 years), primarily women (84.3 vs. 58.2%), commercially insured (70.1 vs. 50.4%) and had more frequent use of antidepressants (30.8 vs. 14.1%) and non‐steroidal anti‐inflammatory drugs (21.7 vs. 12.0%) than those who did not at baseline (all P values < 0.0001).

Conclusions

Few eligible patients received pharmacotherapy for weight loss. Patients who received pharmacotherapy tended to be heavier, younger, female, commercially insured, and used more antidepressants and non‐steroidal anti‐inflammatory drugs.

Impact of Perceived Weight Stigma among Underserved Women on Doctor-Patient Relationships

Objective

The aim of this study was to evaluate how perception of weight stigma among underserved women with obesity impacts doctor–patient relationships.

Methods

This study consisted of an interviewer‐administered survey of 149 women with obesity (body mass index (BMI) > 30 kg m⁻²) immediately after their physician visit at four Federally Qualified Health Centers. Perceptions of weight stigma and physician empathy were measured using the Stigma Situations in Health Care instrument and Consultation and Relational Empathy (CARE) measure, respectively. Associations of CARE and Stigma scores with BMI and patient characteristics were analysed using Mantel–Haenszel chi‐squared test and ordinal logistic regression.

Results

The mean CARE score was 42.1 (standard deviation 8.4; range 11.0–50.0), and mean stigma score was 4.6 (standard deviation 7.6; range 0–43.0). Each increase in BMI category was associated with almost twofold increased odds of higher perception of stigma (odds ratio, 1.90, 95% confidence interval 1.30–2.78, P = 0.001). BMI was not associated with CARE. However, for each increase in stigma category, the odds of lower CARE score doubled (odds ratio, 0.52, 95% confidence interval 0.36–0.75, P = 0.0005).

Conclusions

While BMI was not associated with perception of physician empathy, higher frequency of weight stigmatizing situations was negatively associated with perception of physician empathy. Reducing weight stigma in primary care could improve doctor–patient relationships and quality of care in patients with obesity.

MASTICATORY FUNCTION OF OBESE CANDIDATES TO BARIATRIC SURGERY FROM DISTINCT SOCIOECONOMIC CLASSES

Background

Obesity and metabolic syndrome can be labeled as worldwide outbreak; thus, both have led to serious public health problem. Oral health can be worsened by both, obesity and metabolic syndrome. Tooth loss harms masticatory function, essential status to whom will be submitted to bariatric surgery.

Aim

Assess masticatory function of obese candidates to bariatric surgery, who belong to distinct socioeconomic class range, in order to recognize hazard factors and the bias of socioeconomic factor in this context.

Methods

Observational cross-section study, with samples comprised by two groups of patients, with distinct socioeconomic class range, one of them belonging to public health system (SUSG) and the other to private clinic (CPG), candidates to bariatric surgery. Were assessed anthropometric data, comorbidities and medicines usage, blood tests, habits and the number of dental functional units.

Results

The groups SUSG and CPG were homogeneous taking into account gender (p=0,890) and age range (p=0,170). The number of dental functional units was higher in the private group (p<0.001). The impaired masticatory function was rather present among public group (p<0.001) and female gender (p<0,001). Regarded as blood tests, fasting glucose was higher in female in SUSG (p<0,001). The following hazard factors have corroborated to have patients rated as impaired masticatory function: belong to public service (OR: 8.420, p=0.003), higher age (OR: 1.186, p<0.001), female gender (OR: 0.153, p=0.029), diabetes mellitus (OR: 2.545, p=0.045) and smokers (OR: 2.951, p=0.043).

Conclusion

The general health and masticatory function of female SUSG were worse, highlighting the socioeconomic condition as hazard factor.

Women's weight and disordered eating in a large Norwegian community sample: the Nord-Trøndelag Health Study (HUNT)

OBJECTIVES

An increasing part of the population is affected by disordered eating (DE) even though they do not meet the full eating disorder (ED) criteria. To improve treatment in the range of weight-related disorders, there is a need to improve our knowledge about DE and relevant correlates of weight problems such as underweight, overweight and obesity. However, studies investigating DE and weight problems in a wide range of ages in the general population have been lacking. This paper explores DE, weight problems, dieting and weight dissatisfaction among women in a general population sample.

DESIGN

Cross-sectional study.

SETTING

The third survey of the Nord-Trøndelag Health Study (HUNT3).

PARTICIPANTS

The population included 27,252 women, aged 19-99 years, with information on DE outcomes and covariates.

OUTCOMES

DE was assessed with an 8-item version of the Eating Attitude Test and the Eating Disorder Scale-5. Body mass index (BMI) was objectively measured. Data on dieting and weight dissatisfaction were collected from self-reported questionnaires and analysed across weight categories. Crude and adjusted logistic and multinomial logistic regression models were used.

RESULTS

High rates of overweight (38%) and obesity (23%) were found. DE was associated with weight problems. In women aged <30 years, 11.8% (95% CI 10.3 to 13.1) reported DE, and 12% (95% CI 11.5 to 12.6) reported DE in women aged >30 years. In those of younger ages (19-29 years), lower weight predicted DE, while increasing weight predicted DE in older aged women (30-99 years). The majority of women were dissatisfied with their weight (58.8%), and 54.1% of the women reported dieting. Neither BMI status nor age was associated with dieting or weight dissatisfaction.

CONCLUSIONS

A high prevalence of DE was observed, and findings suggest that weight problems and DE are not distinct from one another. Dieting was associated with women's weight dissatisfaction, rather than with actual weight. This requires further investigations about directionality of effects.

Interaction Effect between Weight Perception and Comorbidities on Weight Control Behavior in Overweight and Obese Adults: Is There a Sex Difference?

We investigated the interaction effect between body weight perception and chronic disease comorbidities on body weight control behavior in overweight/obese Korean adults. We analyzed data from 9,138 overweight/obese adults ≥20 yr of age from a nationally representative cross-sectional survey. Multiple logistic regression using an interaction model was performed to estimate the effect of chronic disease comorbidities on weight control behavior regarding weight perception. Adjusted odds ratios for weight control behavior tended to increase significantly with an increasing number of comorbidities in men regardless of weight perception (P<0.05 for trend), suggesting no interaction. Unlike women who perceived their weight accurately, women who under-perceived their weight did not show significant improvements in weight control behavior even with an increasing number of comorbidities. Thus, a significant interaction between weight perception and comorbidities was found only in women (P=0.031 for interaction). The effect of the relationship between accurate weight perception and chronic disease comorbidities on weight control behavior varied by sex. Improving awareness of body image is particularly necessary for overweight and obese women to prevent complications.

Gender, Age, and Education Level Modify the Association between Body Mass Index and Physical Activity: A Cross-Sectional Study in Hangzhou, China

Introduction

Numerous studies have reported a strong inverse association between BMI and physical activity in western populations. Recently, the association between BMI and physical activity has been considered bidirectional. This study aimed to examine the associations of body mass index (BMI) with physical activity and sedentary behavior and to explore whether those associations were modified by socio-demographic characteristics.

Materials and Methods

We conducted a multistage random sampling survey in three districts of Hangzhou, China, in 2012. The International Physical Activity Questionnaire long form was used to collect data regarding physical activity and sedentary behavior. A multilevel mixed-effects regression model was used to assess the associations of BMI with physical activity and sedentary behavior.

Results

A total of 1362 eligible people (624 men and 738 women, ages 23-59 years) completed the survey. People who are young or middle-aged and have the highest education level are the most inactive. Significant differences in the associations between physical activity and BMI across socio-demographic groups were identified (sex*BMI, P=0.018; age*BMI, P<0.001; education level*BMI, P=0.030). Women or individuals older than 50 had a higher level of physical activity with increasing BMI. There was no statistically significant association between BMI and sedentary behavior (P=0.450).

Conclusions

The associations between BMI and physical activity were modified by sex, age, and education level in Hangzhou, China.

Factors Related to Self-perceived Health in Rural Men and Women

This study examined self-perceived health status among men and women who live on farms, as well as variations in factors related to negative health status observed by gender. Data were collected in the province of Saskatchewan, Canada, in 2013 through the use of a cross-sectional survey. A multistage sample was developed consisting of farms nested within rural municipalities and then agricultural soil zones. The response rate was 48.8% at the farm level, with a final sample of 2,353 (1,416 men, 937 women) from 1,119 farms. Variables under study included self-reports of health status, as well as demographic, behavioral, and farm operational factors that could influence perceived health status. The analysis was initially descriptive followed by multilevel logistic regression analyses. Self-reports of diagnosed comorbidities were strongly associated with negative health status among both men and women. Daytime sleepiness was more modestly associated with negative health status in both genders. Among men, additional risk factors tended to be functional, and included older age, part-time work status, and binge drinking. Among women, additional risk factors included cigarette smoking, overweight or obesity, and lower levels of education. The study demonstrated that there were both similarities and differences between men and women on farms in the factors related to negative self-perceived health status. These findings should inform the content and targeting of health promotion programs aimed at rural populations.

Pragmatic measurement of health satisfaction in people with type 2 diabetes mellitus using the Current Health Satisfaction Questionnaire

BACKGROUND

The concept of diabetes-related health satisfaction encompasses issues specifically related to living with diabetes (eg, blood glucose, blood pressure levels, body weight). Health satisfaction is more specific than overall health-related quality of life because it considers disease-related factors, and is different from diabetes treatment satisfaction because it addresses issues not specifically related to treatment. Low levels of health satisfaction in people with type 2 diabetes mellitus (T2DM) may negatively affect self-care behaviors and treatment outcomes; however, there are currently no instruments available to assess health satisfaction in this population. This study assessed the measurement properties of a newly constructed, 14-item Current Health Satisfaction Questionnaire (CHES-Q) designed to assess diabetes-related health satisfaction and knowledge of the disease and important laboratory results.

METHODS

In-depth interviews were conducted in 23 adults with T2DM to confirm the content and clarity of the CHES-Q. The revised instrument was administered to 1,015 individuals with T2DM, along with supplemental questionnaires, including the Short Form-36. All subjects completed the questionnaires again 3 to 7 days later. CHES-Q test-retest reliability, construct validity, and known-groups validity were evaluated.

RESULTS

In general, respondents found the CHES-Q to be clear and comprehensive. Test-retest reliability was generally acceptable for all items (≥0.70), except for three that fell just below the widely accepted cut-point of 0.70 (range 0.63-0.69). Convergent and divergent validity was demonstrated based on hypothesized correlations with the Short Form-36. Known-groups validity was confirmed for most CHES-Q items when respondents were split into groups known to differ clinically by body mass index, disease severity, or glycated hemoglobin.

CONCLUSION

Health satisfaction is a unique and important concept to consider when developing individualized strategies for managing T2DM because health satisfaction is a key element of patient-centered care. The CHES-Q allows for the pragmatic assessment of many aspects of diabetes-related health satisfaction in a single questionnaire.

The Relationship between Social Network Body Size and the Body Size Norms of Black and Hispanic Adults

Objective

To examine the relationship between the body size norms of Black and Hispanic adults and the body sizes of their social network members.

Methods

Egocentric network data were examined for 245 adults recruited from 2012–2013 in New York City. A multivariable regression model was used to examine the relationship between participants' perception of normal body size and the body sizes of their network members adjusted for participant age, education, race/ethnicity and network size. Participants' body size norms were also examined stratified by the following characteristics of obese network members: frequency of contact, living proximity, relationship, and importance of relationship.

Results

Index participants were 89% female with mean body mass index 33.5 kg/m². There were 2571 network members identified (31% overweight, 10% obese). In the fully adjusted multivariable model, perception of normal body size increased as the number of network members with obesity increased (p < 0.01). Larger body size norms were associated with increased frequency of contact with obese network members (p = 0.04), and obese members living in the home (p = 0.049).

Conclusions

These findings support a relationship between the body size norms of Black and Hispanic adults and their social network body size.

•

Participants reported a larger body size as normal as the number of social network members with obesity increased.

•

Participants' perception of normal body size increased as frequency of contact with obese members increased.

•

Participants with obese network members living in the home perceived a larger body size as normal.

Prevalence of overweight and obesity and weight loss practice among Beijing adults, 2011

Objective

This study aims to determine the up-to-date prevalence of overweight and obesity, the distributions of body weight perception and weight loss practice in Beijing adults.

Methods

A cross-sectional study was conducted in 2011. A total of 2563 men and 4088 women aged 18–79 years from the general population were included. Data were obtained from questionnaire and physical examination.

Results

The prevalence of overweight (BMI 24–27.9 kg/m²) and obesity (BMI≥28 kg/m²) was 42.1% and 20.3% in men and 35.6% and 17.1% in women, respectively. Age was inversely associated with overweight in both sexes, and obesity in women. Education level was negatively associated with overweight and obesity in women but not in men. Only 49.1% men and 58.3% women had a correct perception of their body weight. Underestimation of body weight was more common than overestimation, especially in men, the older people, and those with low education level. The percentage of taking action to lose weight was inversely associated with men and old age, and positively associated with higher education level, higher BMI, and self-perception as “fat” (OR = 3.78 in men, OR = 2.91 in women). Only 26.1% of overweight/obese individuals took action to lose weight. The top two weight loss practices were to reduce the amount of food intake and exercise.

Conclusion

Overweight and obesity were highly prevalent with high incorrect body weight perceptions in the general adult population in Beijing. Weight loss practice was poor in overweight and obese individuals. Actions at multiple levels are needed to slow or control this overweight and obesity epidemic.

The impact of weight loss on weight-related quality of life and health satisfaction: results from a trial comparing canagliflozin with sitagliptin in triple therapy among people with type 2 diabetes

Type 2 diabetes mellitus (T2DM) is primarily a self-managed disease in which self-care behaviors play an important role in achieving optimal outcomes. Because self-care does not result in immediate tangible or noticeable benefits, adherence to such a regimen can be confusing, difficult, and frustrating. People are more likely to adhere to treatment regimens that offer benefits from the patient perspective, such as convenience, avoidance of hypoglycemic episodes, and weight loss, compared with regimens that do not. In this study, we explored the impact of the average weight loss amount demonstrated with canagliflozin treatment on improvement in 3 patient-relevant outcomes that have been linked to performance of healthy behaviors and better outcomes in T2DM: weight-related quality of life, as measured by the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire, and satisfaction with physical health and emotional health, as measured by the Current Health Satisfaction Questionnaire (CHES-Q), using data from a previously reported study. Weight loss of an amount demonstrated in clinical trials of canagliflozin was associated with improvements in weight-related quality of life and satisfaction with physical and emotional health, concepts shown to be important to the persistent and consistent performance of healthy behaviors.

Percepção da imagem corporal e fatores associados em idosos residentes em município do nordeste brasileiro: um estudo populacional

O objetivo do artigo é verificar a percepção da imagem corporal e fatores associados em idosos residentes em Campina Grande (PB). Trata-se de um estudo transversal, de base populacional e domiciliar, com indivíduos de 60 anos ou mais, de ambos os sexos. A percepção da imagem corporal foi considerada variável dependente para fins de análise e de estudo das possíveis associações. As variáveis independentes avaliadas foram: grupo etário, estado nutricional, número de doenças, percepção de saúde e prática de atividade física regular. Para identificar os fatores associados foram realizadas análises de regressão univariada e multivariada, por meio do SPSS 17.0. Foram avaliados 806 idosos. Os homens apresentaram maior satisfação com a imagem corporal quando comparados às mulheres, e idosos mais velhos apresentaram-se mais satisfeitos que idosos mais jovens. Entre os fatores relacionados à insatisfação nas mulheres, o baixo peso e sobrepeso/obesidade estavam relacionados a um risco aumentado de insatisfação. Entre os homens, idades avançadas constituíram fator de proteção para insatisfação, enquanto baixo peso e sobrepeso/obesidade foram fatores de risco para insatisfação. Os resultados sugerem possível influência do estado nutricional na percepção da imagem corporal, interferindo negativamente na percepção da imagem.

Inherited or Behavior? What Causal Beliefs about Obesity Are Associated with Weight Perceptions and Decisions to Lose Weight in a US Sample?

Objectives. To identify the extent to which (1) beliefs about obesity and obesity-related behaviors distinguish individuals based on weight perception (WP) and (2) beliefs about obesity predict perceived health status and WP and how these in turn predict decisions to try to lose weight. Method. 7456 noninstitutionalized US adults (M_age = 54.13, SD_age = 16.93; 61.2% female; 75.9% White) completed the 2007 Health Information National Trends Survey. Multinomial logistic regressions and structural equation modeling were used to accomplish study objectives. Results. Age, gender, information-seeking, health status, belief that obesity is inherited, and knowledge of fruits and vegetables recommendations distinguished participants based on WP. Beliefs about obesity predicted health status, WP, and trying to lose weight in the general model. The models varied based on gender, race/ethnicity, education, and weight misperception. Conclusion. This study supports the role of beliefs about obesity, WP, and health perceptions in individuals' decisions and actions regarding weight management. This study increases our understanding of gender, race/ethnicity, education, and weight misperceptions differences in decisions to lose weight. This knowledge may lead to targeted interventions, rather than “one size fits all” interventions, to promote health and prevent obesity.

Impact of negative cognitions about body image on inflammatory status in relation to health

OBJECTIVE

Evidence suggests that body dissatisfaction may relate to biological processes and that negative cognitions can influence physical health through the complex pathways linking psychological and biological factors.

DESIGN

The present study investigates the relationships between body image satisfaction, inflammation (cytokine levels), aerobic fitness level and obesity in 96 middle-aged men and women (48 normal and 48 overweight). All participants underwent measurements of body satisfaction, body composition, serological measurements of inflammation and aerobic capabilities assessment.

RESULTS

Body image dissatisfaction uniquely predicted inflammation biomarkers, C-reactive protein and tumour necrosis factor-α, even when controlled for obesity indicators. Thus, body image dissatisfaction is strongly linked to inflammation processes and may promote the increase in cytokines, representing a relative metabolic risk, independent of most traditional risk factors, such as gender, body mass index and intra-abdominal (waist to hip ratio) adiposity.

CONCLUSION

Results highlight the fact that person's negative cognitions need to be considered in psychologically based interventions and strategies in treatment of obesity, including strategies for health promotion. Results contribute to the knowledge base of the complex pathways in the association between psychological factors and physical illness and some important attempts were made to explain the psychological pathways linking cognitions with inflammation.

Body mass index and weight loss in overweight and obese korean women: the mediating role of body weight perception

PURPOSE

This study were to assess the relationships among BMI, body weight perception, and efforts to lose weight in a public sample of Korean women who are overweight and obese and to examine the mediating role of body weight perception on the relationship between BMI and weight loss efforts.

METHODS

This cross-sectional study used data from the 2008 Korea National Health and Nutrition Examination Survey. The sample was 1,739 Korean women 20 years old or older with body mass index (BMI) ≥ 23 kg/m(2). Bivariate relationships among variables of interests were assessed. Three separate regressions were used to test the mediating role of body weight perception on the relationship between BMI and weight loss efforts.

RESULTS

BMI and body weight perception were significant correlates of weight loss efforts. BMI was significantly associated with weight perception, but a large proportion of women underestimated their weight. Weight perception partially mediated the relationship between BMI and weight loss efforts in Korean women.

CONCLUSION

In light of the high prevalence of overweight or obesity and the many health consequences associated with obesity, Korean women should be aware of a healthy body weight and try to achieve that weight. Nursing interventions should consider body weight perception to effectively motivate overweight and obese Korean women to lose weight, as necessary.
