Body image and eating behaviour in interethnic adolescent girls

Body size preferences for women and adolescent girls living in Africa: a mixed-methods systematic review

OBJECTIVE

To synthesise evidence on body size preferences for females living in Africa and the factors influencing these.

DESIGN

Mixed-methods systematic review including searches on Medline, CINHAL, ASSIA, Web of Science and PsycINFO (PROSPERO CRD42015020509). A sequential-explanatory approach was used to integrate quantitative and qualitative findings.

SETTING

Urban and rural Africa.

PARTICIPANTS

Studies of both sexes providing data on body size preferences for adolescent girls and women aged ≥10 years.

RESULTS

Seventy-three articles from twenty-one countries were included: fifty quantitative, fifteen qualitative and eight mixed methods. Most studies reported a preference for normal or overweight body sizes. Some studies of adolescent girls/young women indicated a preference for underweight. Factors influencing preferences for large(r) body sizes included: socio-demographic (e.g. education, rural residency), health-related (e.g. current BMI, pubertal status), psycho-social (e.g. avoiding HIV stigma) and socio-cultural factors (e.g. spouse's preference, social standing, cultural norms). Factors influencing preferences for slim(mer) body sizes included: socio-demographic (e.g. higher socioeconomic status, urban residency, younger age), health-related (e.g. health knowledge, being nulliparous), psycho-social (e.g. appearance, body size perception as overweight/obese) and socio-cultural factors (e.g. peer pressure, media).

CONCLUSIONS

Preference for overweight (not obese) body sizes among some African females means that interventions need to account for the array of factors that maintain these preferences. The widespread preference for normal weight is positive in public health terms, but the valorisation of underweight in adolescent girls/young women may lead to an increase in body dissatisfaction. Emphasis needs to be placed on education to prevent all forms of malnutrition.

Body Image and the Double Burden of Nutrition among South Africans from Diverse Sociodemographic Backgrounds: SANHANES-1

This study investigated the associations between underweight, obesity and body image (BI) among 15+ year-old South Africans with diverse socio-demographic backgrounds. A cross-sectional survey and the analyses of data for 6411 15+ year-old participants in the first South African National Health and Nutrition Examination Survey was undertaken. Body image was compared to body mass index (BMI) and socio-demography. Data were analyzed using SPSS versions 25. Results are in percentages, means, 95% confidence intervals, p-values, and odds ratios. Overall, participants who were obese of which majority: were females, earned ZAR 9601+, completed grade 6, were non-Black men, were married and resided in urban formal areas, were more likely to underestimate their BMI and desire to be lighter. Participants who were underweight of which majority: were males, had no form of income or education, were black men, were not married, resided in less urban and farm areas, were younger than 25 years, were more likely to overestimate their BMI and desire to be heavier. While underweight and obesity were strong determinants of BI, BI was differentiated by socio-demography. These findings have a public health implication that requires special attention to curb the irrepressible underweight and obesity in South Africa.

A comparison of eating disorder patients in India and Australia

BACKGROUND

Eating disorders (EDs) are an emerging concern in India. There are few studies comparing clinical samples in western and nonwestern settings.

AIM

The aim was to compare females aged 16-26 years being treated for an ED in India (outpatients n = 30) and Australia (outpatients n = 30, inpatients n = 30).

MATERIALS AND METHODS

Samples were matched by age and body mass index, and had similar diagnostic profiles. Demographic information and history of eating and exercise problems were assessed. All patients completed the quality-of-life for EDs (QOL EDs) questionnaire.

RESULTS

Indians felt they overate and binge ate more often than Australians; frequencies of food restriction, vomiting, and laxative use were similar. Indians were less aware of ED feelings, such as, "fear of losing control over food or eating" and "being preoccupied with food, eating or their body." Indians felt eating and exercise had less impact on their relationships and social life but more impact on their medical health. No differences were found in the global quality-of-life, body weight, eating behaviors, psychological feelings, and exercise subscores for the three groups.

CONCLUSION

Indian and Australian patients are similar but may differ in preoccupation and control of their ED-related feelings.

Evidence of an overweight/obesity transition among school-aged children and youth in Sub-Saharan Africa: a systematic review

BACKGROUND

Prevalence of childhood overweight/obesity has increased considerably in recent years. The transition to higher rates of overweight/obesity has been well documented in high income countries; however, consistent or representative data from lower income countries is scarce. It is therefore pertinent to assess if rates of overweight/obesity are also increasing in lower income countries, to inform public health efforts.

OBJECTIVE

This systematic review aimed to investigate the evidence for an overweight/obesity transition occurring in school-aged children and youth in Sub Saharan Africa.

METHODS

Studies were identified by searching the MEDLINE, Embase, Africa Index Medicus, Global Health, Geobase, and EPPI-Centre electronic databases. Studies that used subjective or objective metrics to assess body composition in apparently healthy or population-based samples of children and youth aged 5 to 17 years were included.

RESULTS

A total of 283 articles met the inclusion criteria, and of these, 68 were used for quantitative synthesis. The four regions (West, Central, East, and South) of Sub Saharan Africa were well represented, though only 11 (3.9%) studies were nationally representative. Quantitative synthesis revealed a trend towards increasing proportions of overweight/obesity over time in school-aged children in this region, as well as a persistent problem of underweight. Weighted averages of overweight/obesity and obesity for the entire time period captured were 10.6% and 2.5% respectively. Body composition measures were found to be higher in girls than boys, and higher in urban living and higher socioeconomic status children compared to rural populations or those of lower socioeconomic status.

CONCLUSIONS

This review provides evidence for an overweight/obesity transition in school-aged children in Sub Saharan Africa. The findings of this review serve to describe the region with respect to the growing concern of childhood overweight/obesity, highlight research gaps, and inform interventions.

Body figure preference in South African adolescent females: a cross cultural study

BACKGROUND

Eating disorders have traditionally been associated with the white community in South Africa. The emergence of eating disorders among blacks in the mid 1990's appeared to signal a demographic shift. Subsequent data suggested that eating disorders would increase in prevalence amongst black South Africans.

OBJECTIVE

The current study sought to explore body figure preference in a cross cultural South African sample, given the established relationship between body dissatisfaction and eating disorders.

METHODS

The sample comprised a community based, multi-racial adolescent population in both urban (n=1353) and rural (n=361) areas. The Body Figure Preference Test [BFPT] was administered.

RESULTS

Most urban respondents had a desire to be smaller (white=72%; black=61%), whereas rural black respondents were more evenly divided amongst those who were content (31%), desiring to be larger (29%) and desiring to be smaller (40%) [Chi square value=105.309, df=4, p=0.001].

CONCLUSIONS

The findings of the study demonstrate that racial homogenization exists regarding body figure preference within the urban setting. Data from the rural area suggests milieu specific factors in this regard with fewer respondents desiring to be smaller. This may have implications for the emergence of eating disorders in black South African populations, more specifically those in urban areas.

Influência da percepção do peso e do índice de massa corporal nos comportamentos alimentares anormais

OBJETIVO: Estudar a associação entre a percepção do peso corporal, o índice de massa corporal e os comportamentos alimentares anormais. MÉTODOS: Delineamento transversal, de base populacional, com mulheres de 12 a 29 anos, da zona urbana de Porto Alegre, RS (n=513). Para medir a prevalência de comportamentos alimentares anormais utilizou-se o Teste de Atitudes Alimentares 26 (EAT-26) e o Teste de Investigação Bulímica de Edimburgo (BITE), considerados separadamente e em conjunto, e a percepção do peso corporal por meio de 2 perguntas estruturadas: qual era o peso que a mulher julgava ideal e a auto-avaliação sobre seu peso. O índice de massa corporal (IMC) foi calculado por medida de peso e altura aferidos. RESULTADOS: Considerando os instrumentos conjuntamente, 30,2% das mulheres tinham comportamento alimentar de risco, e 11,3% apresentaram comportamento alimentar anormal. Além disso, 82% das mulheres apresentaram IMC normal, sendo que 2% eram magras, e 16% apresentaram IMC de sobrepeso/obesidade. Das mulheres estudadas, 46% tinham o ideal de pesar menos, e 37,8% consideravam-se gordas. Entre as mulheres com IMC normal, 25,2% das que se achavam normais apresentavam comportamento alimentar de risco, e 5,7 % comportamento alimentar anormal. Das mulheres que se consideravam gordas, 47,2% apresentaram comportamento alimentar de risco, e 19,2% tinham comportamento alimentar anormal. Mulheres que se sentiam gordas apresentaram um risco quatro vezes maior de apresentar comportamentos alimentares anormais (razão de odds 4,50; IC 95% 2,88-7,01; p<0,001). CONCLUSÃO: A percepção do peso corporal - sentir-se gorda - mostrou um papel mais importante na determinação dos comportamentos alimentares anormais do que o índice de massa corporal (IMC sobrepeso/obesidade).

Dieting behavior of Asian college women attending a US university

Dieting behavior, body dissatisfaction, self-esteem, and food intake of 73 Asian women attending a US university were investigated and compared retrospectively with attitudes of 247 US-born female students at the same university. The Asian women reported restrained eating and body dissatisfaction only about half as often as the US women did. In both the Asian and US college women, body dissatisfaction scores were significantly correlated to body mass index and self-esteem scores. Fourteen percent of the Asian women in the restrained eating/body dissatisfied group, and 40% of the US students in that group reported intentional vomiting for weight control. Some of the Asian international students practiced undesirable dieting behaviors and reported body dissatisfaction levels similar to those of many US college women. College health professionals should recognize that disordered eating among Asian women must not be overlooked because of stereotypical perceptions about Asian women's body size and type.

Knowledge and Attitudes of University Female Students toward Obesity

A cross-sectional study on 203 university female students aged eighteen to thirty years was carried out to determine their knowledge and attitudes toward obesity. The findings revealed that most of the girls believed that overeating (53%) or overeating in addition to inactivity (26.1%) are the main causes of obesity. However, 50 percent of the girls reported that they did not know the health complications of obesity. In general, attitudes toward certain food fads related to obesity was found to be unsatisfactory. Only 50 percent of the girls knew their height compared to 76 percent who knew their weight. Bodyweight perception was found to be inaccurate in 30 percent of girls with acceptable weight, while 80 percent of overweight girls considered themselves obese. Magazines and television are the main sources of nutrition information for these girls. Intervention programs to correct the food fads and change the food habits of adolescent girls are highly recommended.
