Apolipoprotein E gene polymorphism modifies fasting total cholesterol concentrations in response to replacement of dietary saturated with monounsaturated fatty acids in adults at moderate cardiovascular disease risk

Consumption of ≤10% total energy from fat as saturated fatty acids (SFA) is recommended for cardiovascular disease risk reduction in the UK; however there is no clear guidance on the optimum replacement nutrient. Lipid-associated single-nucleotide polymorphisms (SNPs) have been shown to modify the lipid responses to dietary fat interventions. Hence, we performed a retrospective analysis in 120 participants from the Dietary Intervention and VAScular function (DIVAS) study to investigate whether lipoprotein lipase (LPL) and apolipoprotein E (APOE) SNPs modify the fasting lipid response to replacement of SFA with monounsaturated (MUFA) or n-6 polyunsaturated (PUFA) fatty acids. The DIVAS study was a randomized, single-blinded, parallel dietary intervention study performed in adults with a moderate cardiovascular risk who received one of three isoenergetic diets rich in SFA, MUFA or n-6 PUFA for 16 weeks. After the 16-week intervention, a significant diet-gene interaction was observed for changes in fasting total cholesterol (P = 0.001). For the APOE SNP rs1064725, only TT homozygotes showed a significant reduction in total cholesterol after the MUFA diet (n = 33; -0.71 ± 1.88 mmol/l) compared to the SFA (n = 38; 0.34 ± 0.55 mmol/l) or n-6 PUFA diets (n = 37; -0.08 ± 0.73 mmol/l) (P = 0.004). None of the interactions were statistically significant for the other SNPs. In summary, our findings have demonstrated a greater sensitivity of the APOE SNP rs1064725 to dietary fat composition, with a total cholesterol lowering effect observed following substitution of SFA with MUFA but not n-6 PUFA. Further large intervention studies incorporating prospective genotyping are required to confirm or refute our findings. The trial was registered at www.clinicaltrials.gov as NCT01478958

An ethnographic investigation of maternity healthcare experience of immigrants in rural and urban Alberta, Canada

Background: Canada is among the top immigrant-receiving nations in the world. Immigrant populations may face structural and individual barriers in the access to and navigation of healthcare services in a new country. The aims of the study were to (1) generate new understanding of the processes that perpetuate immigrant disadvantages in maternity healthcare, and (2) devise potential interventions that might improve maternity experiences and outcomes for immigrant women in Canada. Methods: The study utilized a qualitative research approach that focused on ethnographic research design and data analysis contextualized within theories of organizational behaviour and critical realism. Data were collected over 2.5 years using focus groups and in-depth semistructured interviews with immigrant women (n = 34), healthcare providers (n = 29), and social service providers (n = 23) in a Canadian province. Purposive samples of each subgroup were generated, and recruitment and data collection – including interpretation and verification of translations – were facilitated through the hiring of community researchers and collaborations with key informants. Results: The findings indicate that (a) communication difficulties, (b) lack of information, (c) lack of social support (isolation), (d) cultural beliefs, e) inadequate healthcare services, and (f) cost of medicine/services represent potential barriers to the access to and navigation of maternity services by immigrant women in Canada. Having successfully accessed and navigated services, immigrant women often face additional challenges that influence their level of satisfaction and quality of care, such as lack of understanding of the informed consent process, lack of regard by professionals for confidential patient information, short consultation times, short hospital stays, perceived discrimination/stereotyping, and culture shock. Conclusions: Although health service organizations and policies strive for universality and equality in service provision, personal and organizational barriers can limit care access, adequacy, and acceptability for immigrant women. A holistic healthcare approach must include health informational packages available in different languages/media. Health care professionals who care for diverse populations must be provided with training in cultural competence, and monitoring and evaluation programs to ameliorate personal and systemic discrimination

Racial and ethnic differences in general health status and limiting health conditions among American children: parental reports in the 1999 National Survey of America's Families

Working PaperObjectives: This research investigates the association between race/ethnicity and child health and examines the role of family structure, family SES, and healthcare factors in this association. Five major racial/ethnic groups in the United States are studied. Two child health outcomes including parent-rated health and limiting health condition are examined. The analysis is stratified into three age groups: age 0 to 5, age 6 to 11, and age 12 to 17. Design: Cross-sectional study using data from a large nationally representative sample collected in 1999 in the United States. Results: For general health, older age groups tend to exhibit larger racial/ethnic disparities. With few exceptions, minority groups showed higher risk of poor health relative to Whites among children age 6 to 17. In the youngest group (age 0 to 5), only Latinos have significant health disadvantage. As to limiting health condition, black children prior to adolescence are slightly disadvantaged, Native American adolescents are significantly more likely to have limiting conditions, whereas Asian adolescents are better off than Whites. Family SES explains some black, Latino, and Native American effects but not all; and SES does not explain the Asian effects. Family structure and healthcare factors generally do not contribute much to the racial/ethnic differences but they can have significant effects on child health in their own right. We also find that economic resources play a more salient role in child health than parental education especially in younger children. And healthcare factors to some extent explain why children from higher SES family fare better. Conclusion: Racial/ethnic disparities in health start early in life. Except for Asians, class explains a substantial amount but not all of these disparities. Healthcare factors play a prominent role in explaining disparities by class. Structural solution is needed to reduce disparities by race and ethnicity particularly in younger children
