Association between weight perception and socioeconomic status among adults in the Seychelles

BACKGROUND: Few studies have examined the association between weight perception and socioeconomic status (SES) in sub-Saharan Africa, and none made this association based on education, occupation and income simultaneously. METHODS: Based on a population-based survey (n = 1255) in the Seychelles, weight and height were measured and self-perception of one's own body weight, education, occupation, and income were assessed by a questionnaire. Individuals were considered to have appropriate weight perception when their self-perceived weight matched their actual body weight. RESULTS: The prevalence of overweight and obesity was 35% and 28%, respectively. Multivariate analysis among overweight/obese persons showed that appropriate weight perception was directly associated with actual weight, education, occupation and income, and that it was more frequent among women than among men. In a model using all three SES indicators together, only education (OR = 2.5; 95% CI: 1.3-4.8) and occupation (OR = 2.3; 95% CI: 1.2-4.5) were independently associated with appropriate perception of being overweight. The OR reached 6.9 [95% CI: 3.4-14.1] when comparing the highest vs. lowest categories of SES based on a score including all SES indicators and 6.1 [95% CI: 3.0-12.1] for a score based on education and occupation. CONCLUSIONS: Appropriately perceiving one's weight as too high was associated with different SES indicators, female sex and being actually overweight. These findings suggest means and targets for clinical and population-based interventions for weight control. Further studies should examine whether these differences in weight perception underlie differences in cognitive skills, healthy weight norms, or body size ideals

Social-ecological, motivational and volitional factors for initiating and maintaining physical activity in the context of HIV

Sport and exercise can have several health benefits for people living with HIV. These benefits can be achieved through different types of physical activity, adapting to disease progression, motivation and social-ecological options. However, physical activity levels and adherence to exercise are generally low in people living with HIV. At the same time, high drop-out rates in intervention studies are prevalent; even though they often entail more favourable conditions than interventions in the natural settings. Thus, in the framework of an intervention study, the present study aims to explore social-ecological, motivational and volitional correlates of South African women living with HIV with regard to physical activity and participation in a sport and exercise health promotion programme. The qualitative data was produced in the framework of a non-randomised pre-post intervention study that evaluated structure, processes and outcomes of a 10-week sport and exercise programme. All 25 participants of the programme were included in this analysis, independent of compliance. Data was produced through questionnaires, participatory group discussions, body image pictures, research diaries and individual semi-structured interviews. All participants lived in a low socioeconomic, disadvantaged setting. Hence, the psychological correlates are contextualised and social-ecological influences on perception and behaviour are discussed. The results show the importance of considering social-cultural and environmental influences on individual motives, perceptions and expectancies, the fear of disclosure and stigmatisation, sport and exercise-specific group dynamics and self-supporting processes. Opportunities and strategies to augment physical activity and participation in sport and exercise programmes in the context of HIV are discussed.Scopu

Maternal Perception of Child Weight Among Mexicans in California and Mexico

The prevalence of childhood overweight is high in Mexican immigrant communities in the United States. Understanding mother’s perceptions of child weight in immigrants’ country of origin may help to understand this high prevalence. The goal of this study was to examine and compare mothers’ perception of weight in Mexico (MX) and in an immigrant community in California (CA). We assessed perceptions of child weight using a pictorial scale with 314 mothers of 5-year-old children in MX and 60 mothers of 5 year-old-children in CA. We compared maternal reports with children’s objectively measured weight. Using chi-square and Analysis of Variance, we investigated associations of maternal perception of and satisfaction with weight according to socio-demographic characteristics. Mothers were more likely to underestimate their children’s weight in CA than in MX. On average, CA mothers wanted their children to be smaller than they currently were and mothers in MX wanted their children to be bigger than they currently were. This differed by weight status in CA with mothers of normal weight and at-risk-for-overweight children wanting them to be bigger and mothers of overweight children wanting them to be smaller. In order for programs to be effective, mothers must be able to recognize their children as overweight and want to address it. Because underestimation of weight and a desire for a larger size is common in this population, programs to address overweight may be more effective if they focus on alternative benefits of weight control strategies, such as healthy child development

Impact of today's media on university student's body image in Pakistan: a conservative, developing country's perspective

<p>Abstract</p> <p>Background</p> <p>Living in a world greatly controlled by mass media makes it impossible to escape its pervading influence. As media in Pakistan has been free in the true sense of the word for only a few years, its impact on individuals is yet to be assessed. Our study aims to be the first to look at the effect media has on the body image of university students in a conservative, developing country like Pakistan. Also, we introduced the novel concept of body image dissatisfaction as being both negative and positive.</p> <p>Methods</p> <p>A cross-sectional study was conducted among 7 private universities over a period of two weeks in the city of Karachi, Pakistan's largest and most populous city. Convenience sampling was used to select both male and female undergraduate students aged between 18 and 25 and a sample size of 783 was calculated.</p> <p>Results</p> <p>Of the 784 final respondents, 376 (48%) were males and 408 (52%) females. The mean age of males was 20.77 (+/- 1.85) years and females was 20.38 (+/- 1.63) years. Out of these, 358 (45.6%) respondents had a positive BID (body image dissatisfaction) score while 426 (54.4%) had a negative BID score. Of the respondents who had positive BID scores, 93 (24.7%) were male and 265 (65.0%) were female. Of the respondents with a negative BID score, 283 (75.3%) were male and 143 (35.0%) were female. The results for BID vs. media exposure were similar in both high and low peer pressure groups. Low media exposure meant positive BID scores and vice versa in both groups (p < 0.0001) showing a statistically significant association between high media exposure and negative body image dissatisfaction. Finally, we looked at the association between gender and image dissatisfaction. Again a statistically significant association was found between positive body image dissatisfaction and female gender and negative body image dissatisfaction and male gender (p < 0.0001).</p> <p>Conclusions</p> <p>Our study confirmed the tendency of the media to have an overall negative effect on individuals' body image. A striking feature of our study, however, was the finding that negative body image dissatisfaction was found to be more prevalent in males as compared to females. Likewise, positive BID scores were more prevalent amongst females.</p

Perceptions of body size, obesity threat and the willingness to lose weight among black South African adults: a qualitative study

BACKGROUND: The obesity epidemic is associated with rising rates of cardiovascular disease (CVD) among adults, particularly in countries undergoing rapid urbanisation and nutrition transition. This study explored the perceptions of body size, obesity risk awareness, and the willingness to lose weight among adults in a resource-limited urban community to inform appropriate community-based interventions for the prevention of obesity. METHOD: This is a descriptive qualitative study. Semi-structured focus group discussions were conducted with purposively selected black men and women aged 35–70 years living in an urban South African township. Weight and height measurements were taken, and the participants were classified into optimal weight, overweight and obese groups based on their body mass index (Kg/m2). Participants were asked to discuss on perceived obesity threat and risk of cardiovascular disease. Information on body image perceptions and the willingness to lose excess body weight were also discussed. Discussions were conducted in the local language (isiXhosa), transcribed and translated into English. Data was analysed using the thematic analysis approach. RESULTS: Participants generally believed that obesity could lead to health conditions such as heart attack, stroke, diabetes, and hypertension. However, severity of obesity was perceived differently in the groups. Men in all groups and women in the obese and optimal weight groups perceived obesity to be a serious threat to their health, whereas the overweight women did not. Obese participants who had experienced chronic disease conditions indicated strong perceptions of risk of obesity and cardiovascular disease. Obese participants, particularly men, expressed willingness to lose weight, compared to the men and women who were overweight. The belief that overweight is ‘normal’ and not a disease, subjective norms, and inaccessibility to physical activity facilities, negatively influenced participants’ readiness to lose weight. CONCLUSION: Low perception of threat of obesity to health particularly among overweight women in this community indicates a considerable challenge to obesity control. Community health education and promotion programmes that increase awareness about the risk associated with overweight, and improve the motivation for physical activity and maintenance of optimal body weight are needed.IS

The assessment of food insecurity in South Africa

MarchThis paper aims to provide a synopsis of available national data sets which may contribute to our better understanding of how food security is conceptualised, defined and assessed within the context of South Africa. More specifically, the paper aims to show that a number of such data sets using different parameters have been used to inform policy and strategies aimed at addressing food insecurity (FI) in the country. Methodologically, the paper presents the various national surveys mostly in a tabular format, highlighting for example the key focus areas/indicators, target audiences, sample sizes, survey time intervals and primary sampling units. Of particular note is that each of these data sets addresses FI in a way that reflects the survey-specific terms of reference of a given national survey, and has its own unique methodological approach with varying strengths and weaknesses. In addition, each of these data sets measures different dimensions of FI. By the very nature of the various surveys included in this review - the National Food Consumption Surveys (NFCS), FI and Vulnerability Information Management System (FIVIMS; regional study), General Household Survey (GHS), Income and Expenditure Survey (IES), Labour Force Survey (LFS), Community Surveys and the national HIV/AIDS surveys the findings from these data sets differ. Comparing such findings, therefore, presents its own challenges and requires due care when attempting to define the prevalence of FI in the country. Based on the technical differences and/or similarities of the surveys and their key findings, the paper draws conclusions and makes recommendations on the need for a more focused and integrated approach to measure FI. Finally, and despite the potential for the better utilisation of the existing data sets, this review argues in favour of a more food securityspecific national survey approach

Intra-familial and ethnic effects on attitudinal and perceptual body image: a cohort of South African mother-daughter dyads

BACKGROUND: International studies suggest ethnic differences in obesity prevalence may be due, in part, to differences in body image and body size dissatisfaction between groups. Further, there is evidence to suggest that there is a familial resemblance in body image between mothers and their younger (preadolescent) daughters. This research was therefore conducted to specifically identify the extent to which family status (presented as mother-daughter resemblance) and ethnicity impact on body image attitudes and perceptions of South African mothers and their pre-adolescent daughters. METHODS: Mother-daughter dyads (n = 201, 31% black, 37% mixed ancestry and 32% white) answered questions regarding their body image perception (the way they saw their body size status), their body image ideals, and body image attitudes (body size dissatisfaction in particular, presented as the Feel-Ideal Difference [FID] index score). Mothers' and daughters' body image results were compared within dyads and across ethnic groups using repeated measures of ANOVA. RESULTS: Overall, body image resemblances exist between South African mothers and their pre-adolescent daughters. Mothers and daughters chose similarly weighted silhouettes to represent their body size ideals (p = 0.308), regardless of their ethnicity or body mass index (BMI). The FID index scores were similar between mothers and their daughters only after the confounding effects of maternal BMI were removed (p = 0.685). The silhouettes chosen to represent thinness were also similar between mothers and their daughters (p = 0.960) regardless of ethnicity and maternal BMI. On the other hand, the silhouettes chosen to represent fatness were similar (p = 0.342) between mothers and their daughters, only after the confounding effects of maternal BMI were removed. Lastly, mothers and their daughters chose similarly weighted silhouettes as engendering feelings of beauty, respect and happiness (p = 0.813; p = 0.615 and p = 0.693, respectively). In this instance, black mother-daughter dyads chose significantly heavier silhouettes than the other ethnic groups. This implies that black mothers and daughters associate beauty, respect and happiness with a bigger body size. CONCLUSION: Resemblances exist between pre-adolescent girls and their mothers on issues related to ideal and attitudinal body image. In this regard, South African researchers should consider the effects ethnicity and family status on body image of women when developing targeted interventions to prevent or manage obesity
