RESUMO

People with intellectual disabilities generally have poorer health outcomes compared with those who do not, including outcomes related to nutrition-related non-communicable diseases. Carers support people with intellectual disabilities in many aspects including habitual shopping and preparation of food, but their own nutrition knowledge and the influence this may have on dietary intakes of clients is unknown. We explored the nutrition knowledge of carers of people with intellectual disabilities in residential care settings, their dietary habits and their influence on clients' food shopping and preparation and therefore the diet consumed by their clients. Ninety-seven carers belonging to a large independent care sector organisation specialising in the care of people with an intellectual disability completed a validated general nutrition knowledge and behaviour questionnaire. Seventeen carers from the residential care settings were interviewed to contextualise practice. Knowledge about key dietary recommendations scored highly. Carers who had more work experience were found to have higher scores in 'making everyday food choices' (p = 0.034). Daily consumption of fruit and vegetables (at least one portion per day) was observed (for fruit by 46% of the carers and for vegetables by 60% of the carers), whilst most carers reported avoiding consuming full-fat dairy products, sugary foods and fried foods. The concept of a healthy diet; typical dietary habits of clients; role in food acquisition; and training in nutrition emerged as themes from the interviews. Carers discussed various topics including the importance of a balanced diet, cooking fresh foods and control of food portion sizes for clients relative to the care philosophy of a client-centred approach, which encapsulates client autonomy. Gaps in knowledge around specific nutrients, making healthy choices and cooking skills remain. Carers have an influence on clients' dietary choices; they are able to provide healthy meals and share good dietary habits with clients. Further training in nutrition is recommended for impact on clients' health.

RESUMO

Background: Student life is often accompanied by changes in eating behavior. Adopting a balanced and varied diet and healthy eating habits can promote the health, growth and intellectual development of young people at different stages of life. According to the WHO, a healthy diet helps protect against all forms of malnutrition, as well as against noncommunicable diseases. The nutritional and energy intake must follow nutritional norms, for example energy intake must be adapted to expenditure. To avoid excessive weight gain, fat should not exceed 30% of total energy intake. Objective: The goal of this study was to compare energy consumption, macronutrients and selected minerals in food rations consumed by students at university campus and at home. Materials and Method: The subjects were chosen at random from among volunteer students from Hassan II University in Casablanca. A sample of 130 students (54 women and 76 men) aged 18 to 25, participated in this study. Anthropometric measurements were performed to assess general characteristics, and records of one-day food intakes at university and at the parental home were performed by 24-hour food diary, and as well as conducting face-to-face. Variables were expressed as mean ± standard deviation (SD). The Kolmogorov-Smirnov test was used to check the normality of data. Results: In accordance with the body mass index classifications, 69.5% of male university students and 77.7% of female were in normal weight categories. The overweight classes were 25.1% and 5.6%, respectively, for men and women. Assessment of the energy and nutritional intakes of university and home meals shows that students consume more calories, protein, carbohydrates, sodium, potassium, and iodine at home than at university, but these contributions remain insufficient in relation to the RDAs. Students consume more fat, especially saturated fatty acids, at university than at home. More than half of students exceed the recommended daily recommendations for saturated fatty acids. Conclusion: These results indicate that a university students' diet is influenced by their behaviors, attitudes, and knowledge. Hence the importance of nutrition education, based on what foods to consume rather than what foods to avoid, a societal issue that requires a multidisciplinary, multisectoral and culturally appropriate approach.

RESUMO

The Ghanaian population is experiencing an upsurge in obesity and type 2 diabetes (T2D) due to rapid urbanization. Besides dietary factors, vitamin D-related genetic determinants have also been shown to contribute to the development of obesity and T2D. Hence, we aimed to examine the interactions between dietary factors and vitamin D-related genetic variants on obesity and T2D related outcomes in a Ghanaian population. Three hundred and two healthy Ghanaian adults (25-60 years old) from Oforikrom, Municipality in Kumasi, Ghana were randomly recruited and had genetic tests, dietary consumption analysis, and anthropometric and biochemical measurements of glucose, HbA1c, insulin, cholesterol, and triglycerides taken. A significant interaction was identified between vitamin D-GRS and fiber intake (g/day) on BMI (pinteraction = 0.020) where those who were consuming low fiber (≤16.19 g/d) and carrying more than two risk alleles for vitamin D deficiency (p = 0.01) had a significantly higher BMI. In addition, an interaction between vitamin D-GRS and fat intake (g/day) on HbA1c (total fat, pinteraction = 0.029) was found, where participants who had a lower total fat intake (≤36.5 g/d), despite carrying more than two risk alleles, had significantly lower HbA1c (p = 0.049). In summary, our study has identified novel gene-diet interactions of vitamin D-GRS with dietary fiber and fat intakes on metabolic traits in Ghanaian adults.

RESUMO

South Asian women living in the UK are particularly at high risk of obesity-related complications, such as type 2 diabetes and cardiovascular disease. Exposure to large portion sizes is a risk factor for obesity. Specifically designed tableware helps individuals to manage weight by controlling food portion sizes. Thirty-one (n = 31) overweight or obese South Asian adult women participated in a randomised cross-over trial aimed to assess the efficacy, acceptance, and weight change of two guided/calibrated commercially available portion control tools (Utensil set and Crockery Set) used in free-living conditions. Data on acceptance, perceived changes in portion size, frequency, and meal type was collected using paper questionnaires and 3-day diet diaries. Scores describing acceptance, ease of use, and perceived effectiveness were derived from five-point Likert scales from which binary indicators (high/low) were analysed for significance using multivariate variance analysis for repeated measurements. A reduction in BMI was observed at each point of measurement (p = 0.007). For overall tool use, the crockery set scored higher in all areas of acceptance, ease of use, and perceived efficacy for all comparisons. Self-selected portion sizes increased for salads and decreased for cooking oil and breakfast cereals with both tools. Further research to scale up and evaluate similar weight management interventions for this group is warranted.

RESUMO

Previous studies have pointed out a link between vitamin D status and metabolic traits, however, consistent evidence has not been provided yet. This cross-sectional study has used a nutrigenetic approach to investigate the interaction between metabolic-genetic risk score (GRS) and dietary intake on serum 25-hydroxyvitamin D [25(OH)D] concentrations in 396 unrelated Turkish adults, aged 24-50 years. Serum 25(OH)D concentration was significantly lower in those with a metabolic-GRS ≥ 1 risk allele than those with a metabolic-GRS < 1 risk allele (p = 0.020). A significant interaction between metabolic-GRS and dietary fat intake (energy%) on serum 25(OH)D levels was identified (Pinteraction = 0.040). Participants carrying a metabolic-GRS ≥ 1 risk allele and consuming a high fat diet (≥38% of energy = 122.3 ± 52.51 g/day) had significantly lower serum 25(OH)D concentration (p = 0.006) in comparison to those consuming a low-fat diet (<38% of energy = 82.5 ± 37.36 g/d). In conclusion, our study suggests a novel interaction between metabolic-GRS and dietary fat intake on serum 25(OH)D level, which emphasises that following the current dietary fat intake recommendation (<35% total fat) could be important in reducing the prevalence of vitamin D deficiency in this Turkish population. Nevertheless, further larger studies are needed to verify this interaction, before implementing personalized dietary recommendations for the maintenance of optimal vitamin D status.

RESUMO

The aim of the study was to investigate whether lifestyle factors modify the association between fat mass and obesity-associated (FTO) gene single nucleotide polymorphisms (SNPs) and obesity in a Turkish population. The study included 400 unrelated individuals, aged 24-50 years recruited in a hospital setting. Dietary intake and physical activity were assessed using 24-hour dietary recall and self-report questionnaire, respectively. A genetic risk score (GRS) was developed using FTO SNPs, rs9939609 and rs10163409. Body mass index and fat mass index were significantly associated with FTO SNP rs9939609 (p = 0.001 and p = 0.002, respectively) and GRS (p = 0.002 and p = 0.003, respectively). The interactions between SNP rs9939609 and physical activity on adiponectin concentrations, and SNP rs10163409 and dietary protein intake on increased waist circumference were statistically significant (Pinteraction = 0.027 and Pinteraction = 0.044, respectively). Our study has demonstrated that the association between FTO SNPs and central obesity might be modified by lifestyle factors in this Turkish population.

RESUMO

Obesity is a multifactorial condition arising from the interaction between genetic and lifestyle factors. We aimed to assess the impact of lifestyle and genetic factors on obesity-related traits in 302 healthy Ghanaian adults. Dietary intake and physical activity were assessed using a 3 day repeated 24 h dietary recall and global physical activity questionnaire, respectively. Twelve single nucleotide polymorphisms (SNPs) were used to construct 4-SNP, 8-SNP and 12-SNP genetic risk scores (GRSs). The 4-SNP GRS showed significant interactions with dietary fat intakes on waist circumference (WC) (Total fat, Pinteraction = 0.01; saturated fatty acids (SFA), Pinteraction = 0.02; polyunsaturated fatty acids (PUFA), Pinteraction = 0.01 and monounsaturated fatty acids (MUFA), Pinteraction = 0.01). Among individuals with higher intakes of total fat (>47 g/d), SFA (>14 g/d), PUFA (>16 g/d) and MUFA (>16 g/d), individuals with ≥3 risk alleles had a significantly higher WC compared to those with <3 risk alleles. This is the first study of its kind in this population, suggesting that a higher consumption of dietary fatty acid may have the potential to increase the genetic susceptibility of becoming centrally obese. These results support the general dietary recommendations to decrease the intakes of total fat and SFA, to reduce the risk of obesity, particularly in individuals with a higher genetic predisposition to central obesity.

RESUMO

This review aims to explore trends of early consumption of sugar-sweetened beverages (SSB) in sub-Saharan Africa (SSA), within the context of growing child and adolescent obesity and escalating type-2 diabetes prevalence. We explore efforts to mitigate these, drawing on examples from Africa and elsewhere. SSB, including carbonated drinks and fruit juices, play a contributory role in the development of obesity and associated non-communicable diseases (NCD). SSA is an attractive market for beverage companies owing to its rapid economic growth, growing middle class and youthful populations. SSB already contribute significantly to total sugar and energy consumption in SSA where a plethora of marketing techniques targeted at younger people are utilised to ensure brand recognition and influence purchasing and brand loyalty. Coupled with a general lack of nutrition knowledge or engagement with preventative health, this can lead to frequent consumption of sugary drinks at a young age. Public health efforts in many high income and some middle-income countries address increasing prevalence of obesity and type-2 diabetes by focusing on strategies to encourage reduction in sugar consumption via health policy and public education campaigns. However, similar efforts are not as developed or forthcoming in low-income countries. Health care systems across SSA are ill-prepared to cope with epidemic proportions of NCD, particularly when contextualised with the ongoing battle with infectious diseases. We conclude that greater efforts by governments and the nutrition community to educate the public on the health effects of increased and excessive consumption of SSB are necessary to help address this issue.

RESUMO

The use of the nutrition facts label has been associated with healthy eating behaviors for adults. However, the relationship between nutrition facts label use and overall diet quality is not well known in young adults, a vulnerable group that acquire lifelong eating behaviors during this period of life. This study aimed to assess if the use of information on the nutrition facts label is associated with a higher diet quality in young adults. In this cross-sectional study, 958 university students aged 18⁻34 years were recruited. Nutrition facts label use was recorded. Dietary intake was assessed using 24-h dietary recall. Healthy Eating Index-2005 (HEI-2005) scores were calculated. HEI-2005 score was significantly associated with using nutrition facts label (p < 0.001). The mean total HEI-2005 score was 60.7 ± 10.11, 62.4 ± 11.43 and 67.1 ± 12.23 respectively for never, sometimes and everytime users of nutrition facts label (p < 0.001). Sub-group scores of HEI-2005 for total fruits, whole fruits, total vegetables, whole grains, milk, oils, saturated fat, and calories from solid fat, alcohol and added sugar (SoFAAS) were significantly higher in regular nutrition facts label users (p < 0.05, for each). This study showed that young adults who regularly use the nutrition facts label have a higher diet quality.

RESUMO

BACKGROUND: Several candidate genes have been identified in relation to lipid metabolism, and among these, lipoprotein lipase (LPL) and apolipoprotein E (APOE) gene polymorphisms are major sources of genetically determined variation in lipid concentrations. This study investigated the association of two single nucleotide polymorphisms (SNPs) at LPL, seven tagging SNPs at the APOE gene, and a common APOE haplotype (two SNPs) with blood lipids, and examined the interaction of these SNPs with dietary factors. METHODS: The population studied for this investigation included 660 individuals from the Prevention of Cancer by Intervention with Selenium (PRECISE) study who supplied baseline data. The findings of the PRECISE study were further replicated using 1238 individuals from the Caerphilly Prospective cohort (CaPS). Dietary intake was assessed using a validated food-frequency questionnaire (FFQ) in PRECISE and a validated semi-quantitative FFQ in the CaPS. Interaction analyses were performed by including the interaction term in the linear regression model adjusted for age, body mass index, sex and country. RESULTS: There was no association between dietary factors and blood lipids after Bonferroni correction and adjustment for confounding factors in either cohort. In the PRECISE study, after correction for multiple testing, there was a statistically significant association of the APOE haplotype (rs7412 and rs429358; E2, E3, and E4) and APOE tagSNP rs445925 with total cholesterol (P = 4 × 10- 4 and P = 0.003, respectively). Carriers of the E2 allele had lower total cholesterol concentration (5.54 ± 0.97 mmol/L) than those with the E3 (5.98 ± 1.05 mmol/L) (P = 0.001) and E4 (6.09 ± 1.06 mmol/L) (P = 2 × 10- 4) alleles. The association of APOE haplotype (E2, E3, and E4) and APOE SNP rs445925 with total cholesterol (P = 2 × 10- 6 and P = 3 × 10- 4, respectively) was further replicated in the CaPS. Additionally, significant association was found between APOE haplotype and APOE SNP rs445925 with low density lipoprotein cholesterol in CaPS (P = 4 × 10- 4 and P = 0.001, respectively). After Bonferroni correction, none of the cohorts showed a statistically significant SNP-diet interaction on lipid outcomes. CONCLUSION: In summary, our findings from the two cohorts confirm that genetic variations at the APOE locus influence plasma total cholesterol concentrations, however, the gene-diet interactions on lipids require further investigation in larger cohorts.

RESUMO

Recent evidence suggests that lifestyle factors influence the association between the Melanocortin 4 receptor (MC4R) and Transcription Factor 7-Like 2 (TCF7L2) gene variants and cardio-metabolic traits in several populations; however, the available research is limited among the Asian Indian population. Hence, the present study examined whether the association between the MC4R single nucleotide polymorphism (SNP) (rs17782313) and two SNPs of the TCF7L2 gene (rs12255372 and rs7903146) and cardio-metabolic traits is modified by dietary factors and physical activity. This cross sectional study included a random sample of normal glucose tolerant (NGT) (n = 821) and participants with type 2 diabetes (T2D) (n = 861) recruited from the urban part of the Chennai Urban Rural Epidemiology Study (CURES). A validated food frequency questionnaire (FFQ) was used for dietary assessment and self-reported physical activity measures were collected. The threshold for significance was set at P = 0.00023 based on Bonferroni correction for multiple testing [(0.05/210 (3 SNPs x 14 outcomes x 5 lifestyle factors)]. After Bonferroni correction, there was a significant interaction between the TCF7L2 rs12255372 SNP and fat intake (g/day) (Pinteraction = 0.0001) on high-density lipoprotein cholesterol (HDL-C), where the 'T' allele carriers in the lowest tertile of total fat intake had higher HDL-C (P = 0.008) and those in the highest tertile (P = 0.017) had lower HDL-C compared to the GG homozygotes. In a secondary analysis of SNPs with the subtypes of fat, there was also a significant interaction between the SNP rs12255372 and polyunsaturated fatty acids (PUFA, g/day) (Pinteraction<0.0001) on HDL-C, where the minor allele carriers had higher HDL-C in the lowest PUFA tertile (P = 0.024) and those in the highest PUFA tertile had lower HDL-C (P = 0.028) than GG homozygotes. In addition, a significant interaction was also seen between TCF7L2 SNP rs12255372 and fibre intake (g/day) on HDL-C (Pinteraction<0.0001). None of the other interactions between the SNPs and lifestyle factors were statistically significant after correction for multiple testing. Our findings indicate that the association between TCF7L2 SNP rs12255372 and HDL-C may be modified by dietary fat intake in this Asian Indian population.

RESUMO

Sub-Saharan Africa (SSA) has traditionally had a low life expectancy due to the onslaught of the HIV epidemic, high levels of chronic diseases, injuries, conflict and undernutrition. Therefore, research into public health concerns of older persons has largely been overlooked. With a growing population, the roll-out of antiretroviral treatment, and the effects of globalisation, SSA is experiencing an increase in the number of people over 50 years of age as well as an increase in the prevalence of non-communicable diseases (NCD). The aim of this review is to highlight available research on the health status of older persons in SSA, and to identify the current gaps that warrant further investigation. A literature search was conducted across multiple databases to identify studies in SSA on older persons (aged 50 years and older) related to health indicators including nutritional status, NCD and HIV burden. While it was concluded that older persons are at an increased risk of poor health, it was also determined that significant gaps exist in this particular area of research; namely nutrient deficiency prevalence. Resources should be directed towards identifying the health concerns of older persons and developing appropriate interventions.

RESUMO

Context: Dietary assessment in minority ethnic groups is critical for surveillance programs and for implementing effective interventions. A major challenge is the accurate estimation of portion sizes for traditional foods and dishes. Objective: The aim of this systematic review was to assess records published up to 2014 describing a portion-size estimation element (PSEE) applicable to the dietary assessment of UK-residing ethnic minorities. Data sources, selection, and extraction: Electronic databases, internet sites, and theses repositories were searched, generating 5683 titles, from which 57 eligible full-text records were reviewed. Data analysis: Forty-two publications about minority ethnic groups (n = 20) or autochthonous populations (n = 22) were included. The most common PSEEs (47%) were combination tools (eg, food models and portion-size lists), followed by portion-size lists in questionnaires/guides (19%) and image-based and volumetric tools (17% each). Only 17% of PSEEs had been validated against weighed data. Conclusions: When developing ethnic-specific dietary assessment tools, it is important to consider customary portion sizes by sex and age, traditional household utensil usage, and population literacy levels. Combining multiple PSEEs may increase accuracy, but such methods require validation.

RESUMO

Community-based growth promotion (CBGP) delivered by community volunteers aims at enhancing the traditional growth monitoring and promotion (GMP) program delivered by community health nurses through the promotion of optimum infant and young child feeding (IYCF) leading to improved child growth. This study compared IYCF knowledge and practices among caregiver-child pairs (0-24 months) receiving child welfare services from CBGP (n = 124) and GMP (n = 108) programs. Semistructured questionnaires were used to interview caregivers on IYCF knowledge/practices and validated food frequency questionnaire used to record infants' food intakes. Group differences were determined using Chi-square and independent samples t-tests (P < 0.05; 95% confidence interval [CI]). Mean IYCF knowledge scores were similar (CBGP: 10.84 ± 1.69 vs. GMP: 10.23 ± 1.38, P = 0.062). However, more CBGP caregivers (17%) were highly knowledgeable than their GMP counterparts (5%) (P = 0.011). Early breastfeeding initiation (CBGP: 54% vs. GMP: 28%, P < 0.0001), exclusive breastfeeding (CBGP: 73% vs. GMP: 56%, P = 0.001), and timely complementary feeding (CBGP: 72% vs. GMP: 49%, P = 0.014) were reportedly higher among CBGP caregivers. Underweight was 11% (CBGP: 8% vs. GMP: 14%, P = 0.154). Mean dietary diversity scores (10 food groups) were similar (CBGP: 4.49 ± 1.89 vs. GMP: 3.87 ± 1.89, P = 0.057) but more CBGP caregivers (77%) achieved minimum dietary diversity than their GMP counterparts (61%) (P = 0.035). Few caregivers achieved minimum meal frequency (CBGP: 31% vs. GMP: 29%, P = 0.486) and minimum acceptable diet (CBGP: 23% vs. GMP: 21%, P = 0.464) indicators. Number of children under 5 years owned by caregiver (adjusted odds ratio [AOR]: 0.405; 95% CI: 1.13-78.53, P = 0.038), her educational level (AOR: 0.112; 95% CI: 0.02-0.90, P = 0.040), and IYCF knowledge (AOR: 0.140; 95% CI: 0.03-0.79, P = 0.026) significantly predicted optimum child feeding. Nutrition education on optimum complementary feeding and birth spacing strategies should intensify.

Breastfeeding duration and exclusive breastfeeding rates are universally below those recommended by World Health Organization. Due to limitations and challenges associated with researching breastfeeding characteristics, the times when exclusivity is likely to be lost and when women are most likely to discontinue breastfeeding have not yet been identified. Prospective food diaries allow reliable description of the dynamics of breastfeeding to be made to help identify these key time periods. Food diaries detailing intake from birth until the cessation of breastfeeding were analysed for 718 infants recruited into a national arm of an international multicentre birth cohort study (EuroPrevall). Analyses included linear regression analysis and Kaplan-Meier time course analysis. Breastfeeding and exclusive breastfeeding cessation rates for younger mothers (<25 years) are high in the first few weeks after delivery but slow markedly in the period 10-12 weeks after delivery. Cessation rates are consistent from 0 to 26 weeks in older mothers. This difference in feeding patterns led to significant differences between the two different age groups at 26 weeks for breastfeeding (P = 0.006) and exclusive breastfeeding at 8 weeks (P = 0.009). Forty-nine per cent of younger mothers (<25 years) stopped breastfeeding before their infant was 3 weeks old. To increase breastfeeding duration, further work is required to investigate the attitudes and perceptions associated with such high breastfeeding cessation rates in younger mothers during these very early post-natal weeks.

RESUMO

The fundamental role played by good nutrition in enabling personal, social and economic development is now widely recognised as presenting a fundamental global challenge that has to be addressed if major national and international problems are to be resolved in the coming decades. The recent focus provided by the Millennium Development Goals and the Scaling-Up-Nutrition (SUN) movement has been towards reducing the extent of nutrition-related malnutrition in high-burden countries. This has served to emphasise that there is a problem of inadequate professional capacity in nutrition that is sufficiently widespread to severely limit all attempts at the effective delivery and sustainability of nutrition-related and nutrition-enabling interventions that have impact at scale. Many high-burden countries are in sub-Saharan Africa where there is a high dependency on external technical support to address nutrition-related problems. We have sought to explore the nature and magnitude of the capacity needs with a particular focus on achieving levels of competency within standardised professional pre-service training which is fit-for-purpose to meet the objectives within the SUN movement in Africa. We review our experience of engaging with stakeholders through workshops, a gap analysis of the extent of the problem to be addressed, and a review of current efforts in Africa to move the agenda forward. We conclude that there are high aspirations but severely limited human resource and capacity for training that is fit-for-purpose at all skill levels in nutrition-related subjects in Africa. There are no structured or collaborative plans within professional groups to address the wide gap between what is currently available, the ongoing needs and the future expectations for meeting local technical and professional capability. Programmatic initiatives encouraged by agencies and other external players, will need to be matched by improved local capabilities to address the serious efforts required to meet the needs for sustained improvements related to SUN in high-burden countries. Importantly, there are pockets of effort which need to be encouraged within a context in which experience can be shared and mutual support provided.

RESUMO

Sub-Saharan Africa has the highest proportion of undernourished people in the world, along with the highest number of people living with HIV and AIDS. Thus, as a result of high levels of food insecurity many HIV patients are also undernourished. The synergism between HIV and undernutrition leads to poor treatment adherence and high mortality rates. Undernutrition has a debilitating effect on the immune system due to key nutrient deficiencies and the overproduction of reactive species (oxidative stress), which causes rapid HIV progression and the onset of AIDS. Therapeutic food supplementation used in the treatment of severe acute malnutrition is being applied to HIV palliative care; however, little biochemical data exist to highlight its impact on oxidative stress and immune recovery. In addition, as most food supplements are imported by donor agencies, efforts are being put into local therapeutic food production such as the Food Multi-Mix concept to ensure sustainability. The purpose of this review is to highlight studies that examine the effectiveness of food supplementation in undernourished HIV patients in Sub-Saharan Africa; noting the parameters used to measure efficacy, as well as the long-term feasibility of supplementation.

RESUMO

The high prevalence of osteoporosis in Pakistan is of public-health concern. However, there is a paucity of information regarding nutrition and bone density in rural communities. The purpose of this study was to evaluate the dietary and lifestyle factors that impact bone health in Nahaqi. Data were collected from 140 postmenopausal women using an interviewer-administered 24-hour dietary recall questionnaire. Bone mineral density was estimated using the quantitative ultrasound index (QUI). Serum 25(OH)D was measured in fasting blood samples. The QUI scores revealed that 42% and 29% of the women had T-scores, indicative of osteopaenia and osteoporosis respectively. The mean calcium intake was 346 mg/d, which is less than 50% of the recommended daily intake. The QUI correlated with 25(OH)D after controlling for age (p=0.021, r=0.41, r2=0.168). Vitamin D deficiency and low intake of dietary calcium are two key factors contributing to poor bone health in this population.

RESUMO

OBJECTIVE: The present qualitative study explored health perceptions, diet and the social construction of obesity and how this relates to the initiation and maintenance of a healthier diet in UK Pakistani women. DESIGN: Pakistani women in Greater Manchester participated in focus group and one-to-one discussions. Semi-structured interviews employing fictional vignettes and body shape images were used to explore the participants' beliefs and practices regarding diet, overweight/obesity and the risk of type 2 diabetes. Transcripts were analysed using phenomenological and sociological approaches. SETTING: Interviews took place either in local community and Pakistani resource centres or in private homes. SUBJECTS: First- and second-generation women who were both active in the community and housebound. The women spoke English and/or Urdu. RESULTS: The fifty-five participants lacked the motivation to address weight gain and were unsure how to do so. There was a limited awareness of the link between weight gain and type 2 diabetes. Other barriers included the influence of Islam, culture and familial expectations on home cooking, perceptions that weight gain is inevitable (owing to ageing, childbirth or divine predestination) and the prioritisation of family concerns over individual lifestyle changes. As the findings of the present research did not correspond to existing educational and behaviour change models, a new Health Action Transition conceptual model is proposed. CONCLUSIONS: Health education programmes that aim to address obesity and its associated risks in the South Asian community must take into account the complex beliefs and practices and the multiple dimensions of religion, ethnic and social identity within this population. The present study provides further insight into these factors and proposes a novel model for use in designing and implementing education interventions for British Pakistani women.
