RESUMO
Background: Women with gestational diabetes mellitus (GDM) have lower rates of exclusive breastfeeding compared with women without diabetes. Objectives: To assess associations between GDM and breastfeeding intentions and attitudes, formula supplementation, reasons for formula supplementation, and knowledge of type 2 diabetes mellitus (T2DM) risk reduction associated with breastfeeding among U.S. mothers. Design/Methods: Participants completed an online survey assessing infant feeding knowledge, attitudes, and practices; demographics; and pregnancy-related medical history. Multivariable logistic regression was used to estimate adjusted odds ratios for formula supplementation in the hospital and at home. Results: Of 871 respondents, a smaller proportion of women with GDM compared with women without diabetes intended to exclusively breastfeed. There were no differences between groups in attitudes toward public breastfeeding, attitudes toward breastfeeding beyond infancy, or actual duration of any breastfeeding. Approximately one in four participants believed that breastfeeding mothers may be less likely to develop T2DM, regardless of GDM status. Among those who intended to exclusively breastfeed, GDM was associated with higher odds of formula supplementation in the hospital (adjusted odds ratio [OR] 1.75, 95% confidence interval [CI] 0.97-3.18) and at home (adjusted OR 2.02, 95% CI 1.05-3.89). "Medical reasons," which was reported as an important reason for formula supplementation, was reported more frequently by women with GDM. Conclusions: Women with GDM who intended to exclusively breastfeed had higher odds of in-hospital and at-home formula supplementation, cited medical reasons as a main reason for formula supplementation more often, and were largely unaware of T2DM risk reduction associated with breastfeeding.
RESUMO
OBJECTIVE: Couplet care is an innovative approach to provide postpartum care in the neonatal intensive care unit (NICU) with little known about its impact on infant feeding outcomes and maternal stress. STUDY DESIGN: We compared breastfeeding outcomes and maternal NICU-related stress among mother-infant dyads based on exposure to couplet care in a prospective cohort study. RESULT: Among 19 couplet-care exposed (CCE) dyads and 19 traditional postpartum care dyads, CCE mothers had lower self-reported stress related to parent-infant relationship as compared to traditional care (P < 0.001). CCE infants received relatively more feeds at the breast (P < 0.001), more breastmilk feeds (P = 0.002), and fewer feeds by staff (P < 0.001). Adjusted for gestational age, marital status, and infant length of stay, couplet care was associated with being in a higher tertile of percent breastmilk feeds (aOR 7.29, 95% CI 1.45-36.65). CONCLUSION: NICU couplet care was associated with improved parental stress and breastfeeding outcomes during hospitalization.
RESUMO
Higher levels of omega-3 fatty acids in red blood cell membranes (omega-3 index or O3I) and cardiorespiratory fitness (CRF) are each associated with reduced cognitive impairment, but little research has examined the relationship between O3I and cognitive function while accounting for CRF. We analyzed cross-sectional data from 5,464 healthy men and women aged 55-85 years who had preventive medical examinations between 2009 and 2023. Primary exposures included O3I (<4.0%, 4.0-7.9%, or ≥ 8.0%) and age- and sex-based CRF quintile (1 = low, 2-3 = moderate, 4-5 = high). Cognitive impairment was defined as a Montreal Cognitive Assessment score of ≤ 25. We used Poisson regression to estimate relative risks (RR) of cognitive impairment, controlling for covariates. O3I < 4% was associated with increased cognitive impairment relative to ≥ 8.0% (RR, 1.21; 95% CI, 1.01-1.44) in a partially adjusted model. This association did not remain statistically significant in the fully adjusted model which included CRF. Low versus high CRF was associated with cognitive impairment (RR, 1.28; 95% CI, 1.07-1.53), independent of O3I and clinical biomarkers. The interaction between CRF and O3I was not significant (P = 0.8). In joint association analysis, risk of cognitive impairment was elevated with lower omega-3 index or CRF or both. Additional research is needed to fully understand the association between O3I and cognitive function at varying CRF levels.
RESUMO
Objective: To compare the experiences of Imposter Phenomenon and discrimination among non-Hispanic White (NHW) and racial and ethnic minority (REM) students at a predominantly White Institution (PWI). Participants: 125 undergraduate students (89.6% women, 68.8% NHW, and 31.2% REM). Methods: Participants completed an online questionnaire including the Clance Imposter Phenomenon Scale (CIPS), Everyday Discrimination Scale (EDS), demographic variables (class year, gender, first generation student status), and 5 items assessing students' feelings of belonging and support. Descriptive statistics and bivariate analyses were performed. Results: Mean CIPS scores were similar for NHW (64.05 ± 14.68) and REM students (63.62 ± 15.90, P = . 882), but EDS scores were significantly higher among REM students (13.00 ± 9.24 vs. 8.00 ± 5.21, P = . 009). REM students more frequently felt that they don't belong, are excluded, and lack resources to succeed. Conclusions: Racial and ethnic minority students at PWIs may need additional resources and social support.
RESUMO
Background: Breastfeeding is especially beneficial to women with diabetes and their infants, yet diabetic mothers frequently experience less favorable breastfeeding outcomes. Objectives: To identify facilitators and barriers to breastfeeding for women with diabetes by comparing cognitive and social factors, health and hospital-related factors, and breastfeeding outcomes between women with and without diabetes. Design/Methods: Women with any type of diabetes (n = 28) and without diabetes (n = 29) were recruited during pregnancy. Data were collected from the electronic medical record and maternal surveys at 24-37 weeks' gestation, birth hospitalization, and 4 weeks' postbirth. We compared differences in mother's regard for breastfeeding, breastfeeding intention, and birth hospital experience by diabetes status, and estimated odds ratios for exclusive breastfeeding (EBF) and unmet intention to breastfeed. Results: Women with and without diabetes had similar breastfeeding intentions, attitudes, and self-efficacy. Women with diabetes were less likely to EBF, and more likely to have unmet intentions to EBF at hospital discharge, compared to women without diabetes. At 4 weeks' postpartum, there was no difference in breastfeeding by diabetes status, although EBF at hospital discharge was strongly associated with EBF at 4 weeks. Infant neonatal intensive care unit (NICU) admission and hypoglycemia were significantly associated with diabetes status, reduced EBF rates, and unmet breastfeeding intentions. Conclusions: Despite having a strong intent to breastfeed, women with diabetes experienced less favorable early breastfeeding outcomes and were less likely to meet their own breastfeeding goals. These differences may be driven by neonatal complications, such as infant hypoglycemia and NICU admissions, rather than maternal cognitive and social factors.

BACKGROUND: Effects of olive oil on cardiovascular risk have been controversial. We compared the effects of high-polyphenolic extra virgin olive oil (EVOO) and refined olive oil without polyphenols on endothelial function (EF) in adults at risk for Type 2 diabetes mellitus (T2DM). METHODS: Randomized, controlled, double-blind, crossover trial of 20 adults (mean age 56.1 years; 10 women, 10 men) at risk for T2DM (i.e., as defined by either prediabetes or metabolic syndrome) assigned to one of two possible sequence permutations of two different single dose treatments (50 mL of high-polyphenolic EVOO or 50 mL of refined olive oil without polyphenols), with 1-week washout. Participants received their olive oils in a smoothie consisting of ½ cup frozen blueberries and 1 cup (8 oz) low-fat vanilla yogurt blended together. Primary outcome measure was EF measured as flow-mediated dilatation. Participants were evaluated before and 2 h after ingestion of their assigned olive oil treatment. RESULTS: EVOO acutely improved EF as compared to refined olive oil (1.2 ± 6.5% versus -3.6 ± 3.8%; p = 0.0086). No significant effects on systolic or diastolic blood pressure were observed. CONCLUSIONS: High-polyphenolic EVOO acutely enhanced EF in the study cohort, whereas refined olive oil did not. Blood pressure effects were not observed. Reports on the vascular effects of olive oil ingestion should specify the characteristics of the oil. CLINICAL TRIAL REGISTRATION NUMBER: NCT04025281.

Gestational diabetes mellitus (GDM) is a disease of glucose intolerance during pregnancy and is associated with infant macrosomia, infant hypoglycemia, and increased risk of type 2 diabetes development for both mother and infant. Although breastfeeding potentially mitigates metabolic sequelae for both mother and her offspring, women with GDM are more likely to introduce formula and, therefore, are less likely to exclusively breastfeed, and some studies show less initiation and shorter breastfeeding duration as well. Therefore, women with GDM and their infants warrant investigation of methods by which to increase breastfeeding exclusivity and duration. Exploration of the barriers to breastfeeding for women with GDM demonstrate not only biologic complications such as maternal obesity, increased prevalence of cesarean section, and infant hypoglycemia, but also maternal report of less provider support of breastfeeding and reduced breastfeeding self-efficacy. Consequently, interventions designed to optimize breastfeeding outcomes in this high-risk population should not only focus on the biology but also on provider behavior and maternal social factors.

Prevailing definitions of protein quality are predicated on considerations of biochemistry and metabolism rather than the net effects on human health or the environment of specific food sources of protein. In the vernacular, higher "quality" equates to desirability. This implication is compounded by sequential, societal trends in which first dietary fat and then dietary carbohydrate were vilified during recent decades, leaving dietary protein under an implied halo. The popular concept that protein is "good" and that the more the better, coupled with a protein quality definition that favors meat, fosters the impression that eating more meat, as well as eggs and dairy, is desirable and preferable. This message, however, is directly opposed to current Dietary Guidelines for Americans, which encourage consumption of more plant foods and less meat, and at odds with the literature on the environmental impacts of foods, from carbon emissions to water utilization, which decisively favor plant protein sources. Thus, the message conveyed by the current definitions of protein quality is at odds with imperatives of public and planetary health alike. We review the relevant literature in this context and make the case that the definition of protein quality is both misleading and antiquated. We propose a modernized definition that incorporates the quality of health and environmental outcomes associated with specific food sources of protein. We demonstrate how such an approach can be adapted into a metric and applied to the food supply.

OBJECTIVE: To identify differences in breastfeeding-related knowledge, attitudes, beliefs, and experiences between women with gestational diabetes mellitus (GDM) and women without GDM. DESIGN: Cross-sectional and prospective cohort study. SETTING: Secondary analysis of data from the U.S. Infant Feeding Practices Study II. PARTICIPANTS: Pregnant women with GDM (n = 195) and pregnant women without GDM (n = 2,815) were included in cross-sectional analyses. For prospective analyses, complete data were available at the postpartum time point for 107 women with and 1,626 women without GDM. METHODS: We compared women with and without GDM for breastfeeding knowledge, attitudes, and beliefs during pregnancy and hospital experiences and problems with breastfeeding after birth. We used multivariate logistic regression to estimate associations between GDM and dependent variables. RESULTS: Women with GDM were less likely to say that breastfeeding is the best way to feed an infant (adjusted odds ratio [aOR] = 0.62, 95% confidence interval [CI] [0.46, 0.85]), more likely to say that the fathers of their infants prefer formula feeding (aOR = 1.74, 95% CI [1.02, 2.97]) or mixed feeding (aOR = 1.78, 95% CI [1.21, 2.61]), and more likely to say their physicians prefer formula (aOR = 2.82, 95% CI [1.17, 6.79]). Women with GDM were less likely to report feeling comfortable breastfeeding in front of female friends (aOR = 0.70, 95% CI [0.50, 0.98]). Newborns of women with GDM were less likely to stay in their mothers' hospital rooms (aOR = 0.55, 95% CI [0.36, 0.85]). CONCLUSION: We identified differences in breastfeeding-related knowledge, attitudes, beliefs, and experiences between women with GDM and women without GDM that could be targets for further research and intervention.

PURPOSE OF REVIEW: Evidence has clearly demonstrated the importance of lifestyle factors (e.g., diet, physical activity, smoking) in the development of cardiovascular disease (CVD). Interventions targeting these behaviors may improve outcomes for CVD patients. The aim of this review is to summarize the effects of lifestyle interventions in individuals with established CVD. RECENT FINDINGS: Most recent trials focused on diet, physical activity, stress reduction, or a combination of these. Findings were mixed, but most interventions improved at least some markers of cardiovascular risk. Few studies measured long-term clinical outcomes, but some suggested a possible benefit of stress reduction and multifaceted interventions on cardiovascular events. The benefits of lifestyle change for CVD patients have been established by decades of evidence. However, further research is needed to determine the optimal intensity, duration, and mode of delivery for interventions. Additional studies with long-term follow-up and measurement of clinical outcomes are also needed.

PURPOSE: To compare the effects of nut-based snack bars (NBSB) vs. prepackaged 200-kcal portions of typical conventional snack foods, when consumed over a 12-week period by a group of overweight adults. DESIGN: Randomized, single-blind parallel design with two treatment groups. SUBJECTS: Thirty-four overweight participants were enrolled. INTERVENTION: Commercially available NBSB or conventional snack foods as part of an ad libitum diet for 12 weeks. PRIMARY OUTCOME MEASURES: body mass index, body weight, body composition, waist circumference. SECONDARY OUTCOME MEASURES: blood pressure, lipid profile, nutrients intake, hunger/satiety, quality of life. ANALYSIS: Generalized linear models with time as repeated measure were used to analyze these data. RESULTS: Daily consumption of NBSB for 12 weeks, as compared to daily consumption of conventional snacks, significantly reduced percentage body fat (-1.7% ± 10.8% vs. 6.2% ± 9.3%; p = .04) and visceral fat (-1.3 ± 5.9 vs. 2.7 ± 4.0; p = .03). There were no between-group differences (p > .05) for blood pressure, lipid panel, satiety, or quality of life measures. CONCLUSION: Our data suggest that daily consumption of NBSB for 12 weeks reduced body fat and had no adverse effects on weight, blood pressure, lipid profile, satiety, or quality of life in this small sample of overweight adults.

PURPOSE: To compare two intensity levels (standard vs. enhanced) of a nutrition and physical activity intervention vs. a control (usual programs) on nutrition knowledge, body mass index, fitness, academic performance, behavior, and medication use among elementary school students. DESIGN: Quasi-experimental with three arms. SETTING: Elementary schools, students' homes, and a supermarket. SUBJECTS: A total of 1487 third-grade students. INTERVENTION: The standard intervention (SI) provided daily physical activity in classrooms and a program on making healthful foods, using food labels. The enhanced intervention (EI) provided these plus additional components for students and their families. MEASURES: Body mass index (zBMI), food label literacy, physical fitness, academic performance, behavior, and medication use for asthma or attention-deficit hyperactivity disorder (ADHD). ANALYSIS: Multivariable generalized linear model and logistic regression to assess change in outcome measures. RESULTS: Both the SI and EI groups gained less weight than the control (p < .001), but zBMI did not differ between groups (p = 1.00). There were no apparent effects on physical fitness or academic performance. Both intervention groups improved significantly but similarly in food label literacy (p = .36). Asthma medication use was reduced significantly in the SI group, and nonsignificantly (p = .10) in the EI group. Use of ADHD medication remained unchanged (p = .34). CONCLUSION: The standard intervention may improve food label literacy and reduce asthma medication use in elementary school children, but an enhanced version provides no further benefit.

BACKGROUND: Comprehensive, residential treatment for severe obesity in adolescents may be an alternative to bariatric surgery and more efficacious than outpatient treatment. The aim of this study was to evaluate the effects of a long-term cognitive-behavioral therapy-based immersion obesity treatment program for adolescents. METHODS: Twelve obese adolescents with BMIs above the 95th percentile completed a 14- to 18-week multicomponent intervention. RESULTS: We observed significant improvements in BMI z-score, waist circumference, mile run time, and blood lipids. CONCLUSION: This study suggests that the tested program may be effective, at least in the short term; a randomized, controlled trial to further assess this model is warranted.
