To examine associations between housing instability and poor diet quality in a sample of urban parents and children. Cross-sectional study of 340 parent/guardian–child dyads visiting a pediatric primary care center in Boston, Massachusetts. The parent/guardian (hereafter, parent) completed 2 Harvard Service Food Frequency Questionnaires, one regarding their own dietary intake and one regarding their child's intake, and an assessment of health-related social needs. Diet quality was measured using the Healthy Eating Index-2010 (HEI-2010; score range 0–100). Housing instability was defined as: 1) homeless or in sheltered housing, 2) doubled up with another family, 3) utilities threatened or shut off, or 4) concerned about eviction. Multivariable logistic regression was used to measure associations between unstable housing and lowest-quartile HEI-2010 scores, adjusting for parent age, race/ethnicity, education, income, and child age. Median (interquartile range) parent and child HEI-2010 scores were 63.8 (56.3–70.8) and 59.0 (54.2–64.7), respectively. Housing instability was found in 136 dyads (40%). In multivariable analysis, it was associated with increased odds of lowest-quartile total parent HEI-2010 scores (adjusted odds ratio [aOR], 1.9; 95% confidence interval [95% CI], 1.1–3.5) but not child scores (aOR, 1.4; 95% CI, 0.8–2.5). It also was associated with increased odds of lowest-quartile parent HEI-2010 dietary component scores for Total vegetables and Greens and beans (aOR, 2.0; 95% CI, 1.1–3.7 and aOR, 2.5; 95% CI, 1.3–4.8, respectively). In this urban primary care population, housing instability is associated with lower diet quality scores for parents but not children. Lower vegetable consumption appears to drive this association.

Puerto Ricans are burdened by nutrition-related diseases, with greater disease prevalence among Puerto Ricans residing in the continental U.S. compared to those in Puerto Rico (PR). However, little is known about diet quality of these two groups. To compare diet quality of Puerto Ricans in Massachusetts (MA) and PR. Puerto Rican patients from health centers in MA (n = 42) and PR (n = 52) completed a food frequency questionnaire. Diet quality was assessed with the Healthy Eating Index-2010 (HEI). Analysis included Mann-Whitney, Chi square and logistic and quantile regressions. 57.1 % of participants in MA and 19.6 % in PR had a poor diet. Adjusting for age and education, participants in MA were more likely to have a poor diet (OR 3.4; p = 0.02) and lower HEI scores than participants in PR. Diet quality among Puerto Ricans is poor, and is worse among mainland Puerto Ricans compared to islanders. [ABSTRACT FROM AUTHOR]

Background: Despite the centrality of nutrition in the management of type 1 diabetes, the association of diet quality and macronutrient distribution with glycemic control is ambiguous. Objective: This study examined longitudinally the association of dietary intake with multiple indicators of glycemic control in youth with type 1 diabetes participating in a behavioral nutrition intervention study. Design: Participants in a randomized clinical trial of a behavioral nutrition intervention [n = 136; mean ± SD age: 12.8 ± 2.6 y; glycated hemoglobin (HbA1c): 8.1% ± 1.0%; 69.1% using an insulin pump] completed 3-d diet records at baseline and months 3, 6, 9, 12, and 18; masked continuous glucose monitoring (CGM) data were obtained concurrently with the use of the Medtronic iPro CGM system. HbA1c was obtained every 3 mo; 1,5-anhydroglucitol was obtained every 6 mo. Linear mixed-effects regression models estimated associations of time-varying dietary intake variables with time-varying glycemic control indicators, controlling for age, height, weight, sex, Tanner stage, diabetes duration, regimen, frequency of blood glucose monitoring, physical activity, and treatment assignment. Results: HbA1c was associated inversely with carbohydrate and natural sugar, and positively with protein and unsaturated fat. 1,5-Anhydroglucitol was associated positively with fiber intake and natural sugar. Greater glycemic control as indicated by ±1 CGM variable was associated with higher Healthy Eating Index--2005, whole plant food density, fiber, carbohydrate, and natural sugar and lower glycemic index and unsaturated fat. Conclusions: Both overall diet quality and macronutrient distribution were associated with more optimal glycemic control. Associations were more consistent for CGM variables obtained concurrently with dietary intake than for biomarkers of longer-term glycemic control. These findings suggest that glycemic control may be improved by increasing intake of high-fiber, low glycemic--index, carbohydrate-containing foods. This trial was registered at clinicaltrials.gov as NCT00999375. [ABSTRACT FROM AUTHOR]

Objective: To examine whether short-term participation in the Supplemental Nutrition Assistance Program (SNAP) affects food security and dietary quality among low-income adults recruited from a Massachusetts-wide emergency food hotline. Methods: A 3-month, longitudinal study was conducted among 107 adults recruited at the time of SNAP application assistance. Outcomes included household food security (10-item US Department of Agriculture Food Security Survey Module), dietary intake (eg, grains, fruit) and diet quality (modified Alternate Healthy Eating Index). Data were analyzed using paired t tests and multivariable linear regression. Results: Supplemental Nutrition Assistance Program participation was not associated with improved household food security over 3 months (P = .25). Compared with non-participants, SNAP participants increased refined grain intake by 1.1 serving/d (P = .02), from baseline to follow-up. No associations were observed with other foods, nutrients, or dietary quality. Conclusion and Implications: Policies that simultaneously improve household food security and dietary quality should be implemented to support the health of low-income Americans participating in this crucial program.

Background Although cost is a frequently cited barrier to healthful eating, limited prospective data exist. Objective To examine the association of diet cost with diet quality change. Design An 18-month randomized clinical trial evaluated a dietary intervention. Participants and setting Youth with type 1 diabetes duration ≥1 year, age 8.0 to 16.9 years, receiving care at an outpatient tertiary diabetes center in Boston, MA, participated along with a parent from 2010 to 2013 (N=136). Eighty-two percent of participants were from middle- to upper-income households. Intervention The family-based behavioral intervention targeted intake of whole plant foods. Main outcome measures Diet quality as indicated by the Healthy Eating Index 2005 (HEI-2005) (which measures conformance to the 2005 Dietary Guidelines for Americans) and whole plant food density (cup or ounce equivalents per 1,000 kcal target food groups) were calculated from 3-day food records of youth and parent dietary intake at six and four time points, respectively. Food prices were obtained from two online supermarkets common to the study location. Daily diet cost was calculated by summing prices of reported foods. Statistical analyses performed Random effects models estimated treatment group differences in time-varying diet cost. Separate models for youth and parent adjusted for covariates examined associations of time-varying change in diet quality with change in diet cost. Results There was no treatment effect on time-varying diet cost for either youth (β –.49, 95% CI –1.07 to 0.08; P =0.10) or parents (β .24, 95% CI –1.61 to 2.08; P =0.80). In addition, time-varying change in diet quality indicators was not associated with time-varying change in diet cost for youth. Among parents, a 1-cup or 1-oz equivalent increase in whole plant food density was associated with a $0.63/day lower diet cost (β –.63, 95% CI –1.20 to –0.05; P =0.03). Conclusions Improved diet quality was not accompanied by greater cost for youth with type 1 diabetes and their parents participating in a randomized clinical trial. Findings challenge the prevailing assumption that improving diet quality necessitates greater cost. [ABSTRACT FROM AUTHOR]

Abstract: Adherence to a Mediterranean diet has recently been shown to protect against cognitive decline and dementia. It remains unclear, however, whether such protection extends to different ethnic groups and middle-aged individuals and how it might compare with adherence to the US Department of Agriculture''s 2005 Dietary Guidelines for Americans (measured with Healthy Eating Index 2005 [HEI 2005]). This study examined associations between diet quality, as assessed by the Mediterranean diet and HEI 2005, and cognitive performance in a sample of 1,269 Puerto Rican adults aged 45 to 75 years and living in the Greater Boston area of Massachusetts. Dietary intake was assessed with a food frequency questionnaire specifically designed for and validated with this population. Adherence to the Mediterranean diet was assessed with a 0- to 9-point scale, and the HEI 2005 score was calculated with a maximum score of 100. Cognitive performance was measured with a battery of seven tests and the Mini Mental State Examination was used for global cognitive function. Greater adherence to the Mediterranean diet was associated with higher Mini Mental State Examination score (P trend=0.012) and lower likelihood (odds ratio=0.87 for each additional point; 95% CI 0.80 to 0.94; P<0.001) of cognitive impairment, after adjustment for confounders. Similarly, individuals with higher HEI 2005 score had higher Mini Mental State Examination score (P trend=0.011) and lower odds of cognitive impairment (odds ratio=0.86 for each 10 points; 95% CI 0.74 to 0.99; P=0.033). In conclusion, high adherence to either the Mediterranean diet or the diet recommended by the US Department of Agriculture 2005 Dietary Guidelines for Americans can protect cognitive function in middle-aged and older adults.
