A focused ethnographic assessment of Middle Eastern mothers' infant feeding practices in Canada.

The aim of this study was to examine the barriers to following complementary feeding guidelines among Middle Eastern mothers and the cultural considerations of practitioners from an emic perspective. This is a two-phase focused ethnographic assessment of infant feeding among 22 Middle Eastern mothers in Western Canada who had healthy infants aged <1 year. Data were collected through four focus groups conducted in Arabic/Farsi, and were further complemented by comprehensive survey data collected in the second phase of study. Mothers' main criterion for choosing infant foods was whether or not foods were Halal, while food allergens were not causes for concern. Vitamin D supplements were not fed to 18/22 of infants, and mashed dates (Halawi), rice pudding (Muhallabia/Ferni) and sugared water/tea were the first complementary foods commonly consumed. Through constant comparison of qualitative data, three layers of influence emerged, which described mothers' process of infant feeding: socio-cultural, health care system and personal factors. Culture was an umbrella theme influencing all aspects of infant feeding decisions. Mothers cited health care professionals' lack of cultural considerations and lack of relevance and practicality of infant feeding guidelines as the main reasons for ignoring infant feeding recommendations. Early introduction of pre-lacteal feeds and inappropriate types of foods fed to infants among immigrant/refugee Middle Eastern mothers in Canada is cause of concern. Involving trained language interpreters in health teams and educating health care staff on cultural competency may potentially increase maternal trust in the health care system and eventually lead to increased awareness of and adherence to best practices with infant feeding recommendations.

Adherence to Mediterranean-style dietary pattern and risk of esophageal squamous cell carcinoma: a case-control study in Iran.

OBJECTIVE: The benefit of adherence to a Mediterranean-style dietary pattern in relation to the risk of esophageal squamous cell carcinoma (ESCC) has not been investigated among non-Mediterranean high-risk populations. The objective of the present study was to examine the association of compliance with the Mediterranean dietary pattern as measured by Mediterranean-Style Dietary Pattern Score (MSDPS) and the risk of ESCC in Iranian population. METHODS: This case-control study was conducted on 47 ESCC cases and 96 hospital controls aged 40-75 years. Participants were interviewed using validated questionnaires, and dietary patterns were characterized using the MSDPS. RESULTS: Generally, the mean MSDPS in this population was low (30.84 ± 8.58). MSDPS showed content validity through having expected positive associations with several lifestyle characteristics and dietary intakes. Being in the highest quartile category of MSDPS, compared to the lowest, was independently associated with 37% reduction in risk of ESCC. Two-unit and 3-unit increases in the MSDPS resulted in 41% and 47% reduction in risk of ESCC, respectively. Higher intakes of olive oil (odds ratio [OR] = 0.15, 95% CI: 0.01-0.49), fish and other seafood (OR = 0.48, 95% CI: 0.23-0.98), whole grain (OR = 0.57, 95% CI: 0.28-0.76), and fruits (OR = 0.77, 95% CI: 0.38-0.86) were significantly associated with reduced ESCC risk. In contrast, higher sweet (OR = 1.86, 95% CI: 1.04-2.12) and meat intakes (OR = 1.61, 95% CI: 1.25-2.49) were associated with higher ESCC risk. CONCLUSION: Consuming a diet in concordance with the principles of the Mediterranean dietary pattern may protect against ESCC. Preventive strategies to reduce ESCC risk in high-risk countries should focus on overall dietary pattern and dietary habits to be effective.

Macronutrients, vitamins and minerals intake and risk of esophageal squamous cell carcinoma: a case-control study in Iran.

BACKGROUND: Although Iran is a high-risk region for esophageal squamous cell carcinoma (ESCC), dietary factors that may contribute to this high incidence have not been thoroughly studied. The aim of this study was to evaluate the effect of macronutrients, vitamins and minerals on the risk of ESCC. METHODS: In this hospital-based case-control study, 47 cases with incident ESCC and 96 controls were interviewed and usual dietary intakes were collected using a validated food frequency questionnaire. Data were modeled through unconditional multiple logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI), controlling for age, sex, gastrointestinal reflux, body mass index, smoking history (status, intensity and duration), physical activity, and education. RESULTS: ESCC cases consumed significantly more hot foods and beverages and fried and barbecued meals, compared to the controls (p < 0.05). After adjusting for potential confounders, the risk of ESCC increased significantly in the highest tertiles of saturated fat [OR:2.88,95%CI:1.15-3.08], cholesterol [OR:1.53, 95%CI: 1.41-4.13], discretionary calorie [OR:1.51, 95%CI: 1.06-3.84], sodium [OR:1.49,95%CI:1.12-2.89] and total fat intakes [OR:1.48, 95%CI:1.09-3.04]. In contrast, being in the highest tertile of carbohydrate, dietary fiber and (n-3) fatty acid intake reduced the ESCC risk by 78%, 71% and 68%, respectively. The most cancer-protective effect was observed for the combination of high folate and vitamin E intakes (OR: 0.02, 95%CI: 0.00-0.87; p < 0.001). Controls consumed 623.5 times higher selenium, 5.48 times as much ß-carotene and 1.98 times as much α-tocopherol as the amount ESCC cases consumed. CONCLUSION: This study suggests that high intake of nutrients primarily found in plant-based foods is associated with a reduced esophageal cancer risk. Some nutrients such as folate, vitamin E and selenium might play major roles in the etiology of ESCC and their status may eventually be used as an epidemiological marker for esophageal cancer in Iran, and perhaps other high-risk regions.
