Feasibility and acceptability of a Mediterranean-style diet intervention to reduce cardiovascular risk for low income Hispanic American women.

OBJECTIVE: Evidence for the cardioprotective effects of a Mediterranean-style (Med-style) diet is strong, however few Med-style dietary interventions have been developed for and tested among Hispanic Americans (HAs), especially younger HAs of reproductive age whose dietary habits may strongly influence dietary intake for all family members. DESIGN: We adapted a previously tested and evidence-informed lifestyle intervention to reduce CVD risk and evaluated its feasibility, acceptability, and effects on self-reported lifestyle behaviors in this study enrolling low-income HA women attending a Title X family planning clinic in eastern North Carolina. The 3-month long intervention, given to all participants, promoted a Med-style dietary pattern with a focus on increasing consumption of foods commonly consumed by HA that have high quality dietary fats (polyunsaturated and monounsaturated fats primarily from plant sources and fish) and carbohydrates (fruits, vegetables, and whole grains). The intervention also recommended increasing physical activity and was given during 2 face-to-face counseling sessions and 2 telephone counseling sessions. Major outcomes were engagement with study activities and intervention acceptability; lifestyle behavior change at 3-month follow-up is also reported. RESULTS: Baseline characteristics (n = 36) were: mean age 33 years, 35 (97%) without health insurance, 32 (89%) born in Mexico, and mean BMI 30 kg/m2. Engagement was high among the 36 participants with 33 (92%) completing the intervention and follow-up measures. At follow-up, most participants thought the intervention was helpful (range: 85-100%) and acceptable (100% agreed 'I would recommend the program to others'). The mean dietary fat quality score improved by 0.5 units (95% CI: 0.0-1.1) and the mean fruit-vegetable servings/day improved by 0.7/day (95% CI: 0.1-1.3). CONCLUSION: Intervention engagement and acceptability were high and there was improvement in self-reported dietary behaviors. This type of Med-style dietary pattern intervention should be evaluated in randomized trials enrolling HAs at risk for CVD.

Effect of supplementation with a lipid-based nutrient supplement on the micronutrient status of children aged 6-18 months living in the rural region of Intibucá, Honduras.

BACKGROUND: Lipid-based nutrient supplements (LNS) have been effective in the treatment of acute malnutrition among children. We evaluated the use of LNS supplementation for improving the micronutrient status of young children. METHODS: A 12-month randomised controlled trial was conducted among children aged 6-18 months living in Intibucá, Honduras. Communities (n = 18) were randomised into clusters matched by poverty indicators (9 intervention, n = 160 and 9 controls, n = 140). Intervention participants received LNS. All children received food vouchers and nutrition education. Primary outcomes included measures of micronutrient status: at baseline, 6 and 12 months' blood were collected for assessment of folate, iron, zinc, riboflavin, and vitamin B12 status; haemoglobin was measured every 3 months; and dietary and anthropometry collected monthly. Longitudinal analyses were based on intent to treat and LNS adherence. Generalised estimating equations were used in the estimation of generalised linear regression models specified for the data. RESULTS: At 6-month follow-up, children in the intervention group had a lower proportion classified as deficient for B12 (43.6%) compared with the control (67.7%; P = 0.03). The intervention group had a higher mean concentration for folate at 6 months (P = 0.06), and improvements continued through 12 months for folate (P = 0.002) and vitamin A deficiency (P = 0.03). This pattern of results, with improved significance, remained in subanalysis based on LNS adherence. CONCLUSION: These data demonstrate that LNS improved select micronutrient status in young non-malnourished Honduran children.

Risk factors associated with the presence and severity of food insecurity in rural Honduras.

OBJECTIVE: To identify factors associated with the presence and severity of food insecurity among a sample of Honduran caregivers of young children. DESIGN: Cross-sectional study in which the dependent variable, household food insecurity, was measured using a fourteen-item questionnaire developed and validated in a population of similar cultural context. A predictive modelling strategy used backwards elimination in logistic regression and multinomial logit regression models to compute odds ratios and 95% confidence intervals for food insecurity. SETTING: Rural Honduras in the department of Intibucá, between March and April 2009. SUBJECTS: Two-hundred and ninety-eight Honduran caregivers of children aged 6-18 months. RESULTS: Ninety-three per cent of households were classified as having some degree of food insecurity (mild, moderate or severe). After controlling for caregiver age and marital status, compared with caregivers with more than primary-school education, those with less than primary-school education had 3·47 (95% CI 1·34, 8·99) times the odds of severe food insecurity and 2·29 (95% CI 1·00, 5·25) times the odds of moderate food insecurity. Our results also found that child anthropometric status was not associated with the presence or severity of food insecurity. CONCLUSIONS: These results show that among the sociodemographic factors assessed, food insecurity in rural Honduras is associated with maternal education. Understanding key factors associated with food insecurity that are unique to Honduras can inform the design of interventions to effectively mitigate the negative impact of food insecurity on children.

Feasibility and Acceptability of a Clinic-based Mediterranean-style Diet Intervention to Reduce Cardiovascular Risk for Hispanic Americans With Type 2 Diabetes.

Purpose The purpose of the study was to modify a previously tested Spanish language version of a Mediterranean (Med)-style dietary intervention so that the dietary recommendations align with the cultural and social needs of Hispanic Americans (HAs) with type 2 diabetes (T2D) and evaluate the modified intervention's feasibility and acceptability. Methods In phase I (formative), semi-structured interviews and focus groups were used to refine the intervention content and format for delivery to HAs with T2D receiving care at a large primary care practice. In phase II (clinical pilot), the 2-month intervention that promoted a Med-style dietary pattern was given to all participants via 2 face-to-face counseling sessions and 2 telephone counseling sessions. Major outcomes were engagement with study activities and intervention acceptability; dietary behavior change at 2 months using the PREDIMED Med-diet score (range, 0-14, higher indicating better dietary pattern) is also reported. Results From clinic records, we identified 86 potentially eligible participants and enrolled 21. Baseline characteristics were: mean age = 52 years, 12 (57%) female, 15 (71%) from Mexico, mean years in the US = 19, low acculturation scores for all, and mean BMI = 33.7 kg/m2. Engagement and acceptability were high, with 19 (90%) completing all intervention visits and follow-up measures, all of whom would recommend the program to others. Mean Med-diet score improved from 5.7 to 7.9 (difference = 2.3; 95% CI, 1.0-3.5; P = .001). Conclusions Intervention engagement and acceptability were high, and there was improvement in self-reported dietary behaviors. This type of intervention should be evaluated in randomized trials enrolling HAs with diabetes.
