Socio-cultural beliefs about an ideal body size and implications for risk of excess weight gain after immigration: a study of Australian residents of sub-Saharan African ancestry

Re-engaging cultural differences: Culture, morality, trauma and the integration of non-Western migrants

We locate our review of recent social scientific literature on non-Western migrants in Western liberal democracies within two opposing master narratives: a subtractive and an additive view of migration. Within this framework, we bring to light the contemporary conceptualizations of non-Western migrants in psychology by focusing on trauma. We then examine the cultural and moral clashes that sometimes arise from trans-global migration and the psychology of integration. We end by highlighting the importance of further research on cultural pluralism and omniculturalism to help foster more peaceful and diverse societies.

Significantly different roles of economic affluence in sex-specific obesity prevalence rates: understanding more modifications within female body weight management

Socioeconomic status has been associated with obesity prevalence increase in both males and females worldwide. We examined the magnitude of the difference between the two relationships and explored the independence of both relationships. Country specific data on gross domestic product (GDP) per capita, sex-specific obesity prevalence rates, urbanisation, total calories availability and level of obesity, genetic background accumulation (measured by the Biological State Index, I_bs) were obtained for 191 countries. Curvilinear regressions, bivariate and partial correlations, linear mixed models and multivariate linear regression analyses were used to examine the relationship between GDP and obesity prevalence rates in males and females respectively. Fisher’s r-to-z transformation, F-test and R² increment in multivariate regression were used to compare results for males and females. GDP significantly correlated with sex-specific obesity prevalence rates, but significantly more strongly with male obesity prevalence in bivariate correlation analyses. These relationships remained independent of calories availability, I_bs and urbanization in partial correlation model. Stepwise multiple regression identified that GDP was a significant predictor of obesity prevalence in both sexes. Multivariate stepwise regression showed that, when adding GDP as an obesity prevalence predictor, the absolute increment of R² in male fit model (0.046) was almost four (4) times greater than the absolute increment in female model fit (0.012). The Stepwise analyses also revealed that 68.0% of male but only 37.4% of female obesity prevalence rates were explained by the total contributing effects of GDP, I_bs, urbanization and calories availability. In both Pearson’s r and nonparametric analyses, GDP contributes significantly more to male obesity than to female obesity in both developed and developing countries. GDP also determined the significant regional variation in male, but not female obesity prevalence. GDP may contribute to obesity prevalence significantly more in males than in females regardless of the confounding effects of I_bs, urbanization and calories. This may suggest that aetiologies for female obesity are much more complex than for males and more confounders should be included in the future studies when data are available.

Weight Bias Among Nutrition and Dietetics Students in a Ghanaian Public University

OBJECTIVES

To measure the internal consistency reliability of 3 weight bias scales among nutrition and dietetics students enrolled at a public university in Ghana and to use the Fat Phobia Scale (FPS) to determine the prevalence of weight bias and the differences in gender and body mass index.

DESIGN

Online survey gathered self-reported height, weight, and demographic data. Explicit weight bias was assessed using validated FPS, Beliefs About Obese People, and Attitudes Toward Obese Persons scales.

PARTICIPANTS

Sample of 172 students.

MAIN OUTCOME MEASURES

Prevalence of weight bias.

ANALYSIS

Cronbach α reliability test was used to measure the internal consistency of scales. The prevalence of weight bias was expressed as a percentage. Independent t tests and analysis of variance were used to explore differences in gender and weight categories.

RESULTS

The reliability scores for FPS, Beliefs About Obese People, and Attitudes Toward Obese Persons scales were 0.92, 0.51, and 0.38, respectively. About 53% of participants expressed weight bias. A significant difference was observed for weight bias between overweight and obese participants, with participants with obesity showing greater weight bias (P = 0.03).

CONCLUSION AND IMPLICATIONS

Fat Phobia Scale (most reliable) identified more than half of the students had a negative attitude toward obesity. Weight bias training within this population may improve attitudes toward obesity.

Children's longitudinal bodyweight in Australia: Influence of migrant mothers' long-term residency, attachment to, and level of childhood overweight in country-of-birth

Immigration creates opportunities and imposes constraints associated with acculturation. We used the Australian national longitudinal survey of children aged 2 to 17 to evaluate the influence of mothers' long-term residency in Australia, mothers' attachment to country-of-birth, and macro indicators of childhood overweight environment at mothers' country-of-birth on children's longitudinal bodyweight. Both mothers' long-term exposure to the Australian environment and attachment to country-of-birth were associated with increased children's bodyweight z-scores. The childhood overweight environment in mothers' country-of-birth continued to influence their children's bodyweight after immigration. A better understanding of factors related to mothers' migration and children's bodyweight status is necessary to identify risk factors and migrant sub-groups needing extra support.

The Influence of Cultural Experiences on the Associations between Socio-Economic Status and Motor Performance as Well as Body Fat Percentage of Grade One Learners in Cape Town, South Africa

Fundamental movement skills (FMS), physical fitness (PF) and body fat percentage (BF%) are significantly related to socio-economic status (SES). However, it remains unclear why previous studies have had different findings regarding the direction of the association between SES and FMS, PF and BF%. A suggested explanation is that the direction of the link can be influenced by cultural experiences and traditions. Therefore, the aim of the current study was to investigate links between SES and FMS, PF, BF% of Grade One learners from two different ethno-geographic areas in Cape Town, South Africa. Grade One children (n = 191) (n = 106 boys and n = 85 girls; age (6.7 ± 0.33)) from different socio-economic areas in Cape Town, South Africa, were selected to participate in the study. South African schools are classified into five different quintiles (1 = poorest and 5 = least poor public schools). For this study, two schools were selected, one from quintile 2 and the other from quintile 5. BF% was assessed according to Slaughter's equation. FMS were measured using the Gross Motor Development Test-2 (TGMD-2) and PF via five tests: 1. dynamic strength of lower limb (broad jump); 2. dynamic strength of upper limb and trunk (throwing a tennis ball); 3. speed agility (4 × 10 m shuttle running); 4. cardiorespiratory fitness (20 m shuttle run endurance test (Leger test)) and 5. flexibility (sit and reach test). An analysis of covariance (ANCOVA) found that BF% and WHtR were significantly greater in children with higher SES (Z = 6.04 p < 0.001; Hedg = 0.54), (Z = 3.89 p < 0.001; Hedg = 0.32). Children with lower SES achieved significantly better TGMD-2 standard scores in the locomotor subtest, compared to their peers with higher SES. In the object control subtest, no significant SES-related difference was found. However, ANCOVA showed that girls performed better in FMS than boys. In PF, the main effect of SES was observed in dynamic strength of trunk and upper limb (throwing) and flexibility, where children with lower SES performed significantly better. No significant difference was found in cardiorespiratory performance (CRP) (Beep test), even though children with lower SES achieved better results. Results from the current study suggest that links between SES, PF, FMS and body fat percentage in children seem to be dependent on cultural and traditional experiences. These experiences should therefore be included as an important factor for the development of programmes and interventions to enhance children's lifelong motor behaviour and health strategies.

Body size ideals and body satisfaction among Dutch-origin and African-origin residents of Amsterdam: The HELIUS study

OBJECTIVE

Obesity is highly prevalent among ethnic minorities and acceptance of larger body sizes may put these ethnic minorities at risk of obesity. This study aimed to examine body size ideals and body satisfaction in relation to body weight, in two Sub-Saharan African (SSA)-origin groups in the Netherlands compared to the Dutch. Additionally, in the two SSA-origin groups, this study assessed the mediating role of acculturation in the relation between ethnicity and body size ideals and body satisfaction.

METHODS

Dutch, African Surinamese and Ghanaians living in Amsterdam, the Netherlands, participated in the observational HELIUS study (n = 10,854). Body size ideals were assessed using a validated nine figure scale. Body satisfaction was calculated as the concordance of current with ideal figure. Acculturation was only assessed among SSA-origin participants and acculturation proxies included age of migration, residence duration, ethnic identity and social network. Weight and height were measured using standardised protocols.

RESULTS

SSA-origin women and Ghanaian men had larger body size ideals compared to the Dutch; e.g. Surinamese and Ghanaian women had 0.37 (95%CI 0.32; 0.43) and 0.70 (95%CI 0.63; 0.78) larger body size ideals compared to Dutch women. SSA-origin participants were more often satisfied with their weight compared to the Dutch. Similarly, SSA-origin participants had more than twice the odds of being satisfied/preferring a larger figure compared to the Dutch (e.g. BSurinamese men 2.44, 95%CI 1.99; 2.99). Within the two SSA-origin groups, most acculturation proxies mediated the relation between ethnicity and body size ideals in women. Limited evidence of mediation was found for the outcome body satisfaction.

CONCLUSION

Public health strategies promoting a healthy weight may need to be differentiated according to sex and ethnic differences in body weight perception. Factors other than acculturation may underlie the ethnic differences between African Surinamese and Ghanaians in obesity.

The relationship between body shape perception and health behaviors among Korean normal-weight adolescents using Korea Youth Risk Behavior Web-Based Survey

Inappropriate adolescent health behavior can be influenced by the negative impact of physical and mental health promotion. Obesity influences subjective improper weight perception. This study aimed to verify Korean normal-weight adolescents' subjective experience of weight control, mental health, physical activity, and subjective status based on their body mass index (BMI). As a result, efforts to control weight appeared less in normal-weight boys. Thin girls were less likely to carry out 60 min of physical activity 7 or 5 days per a week. Obese boys were less likely to carry out vigorous physical activity 3 days per a week. Normal-weight girls were less likely to practice muscular strength training 3 days per a week. Thin boys and thing girls were less likely to practice regular physical activity, and less likely to practice at the rate stipulated in the sedentary behavior guideline. In conclusion, boys and girls with inappropriate weight perception reported feeling stressed and depressed, and reported subjective sleep fulfillment, perceived subjective happiness, and perceived subjective health.
