RESUMO

BACKGROUND: Breastfeeding (BF) provides optimal nutrition during the first 6 mo of life and is associated with reduced infant mortality and several health benefits for children and mothers. However, not all infants in the United States are breastfed, and sociodemographic disparities exist in BF rates. Experiencing more BF-friendly maternity care practices at the hospital is associated with better BF outcomes, but limited research has examined this association among mothers enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), a population at risk of low BF rates. OBJECTIVES: We assessed the association between BF-related hospital practices (rooming-in, support from hospital staff, and provision of a pro-formula gift pack) and the odds of any or exclusive BF through 5 mo among infants and mothers enrolled in WIC. METHODS: We analyzed data from the WIC Infant and Toddler Feeding Practices Study II, a nationally representative cohort of children and caregivers enrolled in WIC. Exposures included maternal experience of hospital practices reported at 1 mo postpartum, and BF outcomes were surveyed at 1, 3, and 5 mo. ORs and 95% CIs were obtained using survey-weighted logistic regression, adjusting for covariates. RESULTS: Rooming-in and strong hospital staff support were associated with higher odds of any BF at 1, 3, and 5 mo postpartum. Provision of a pro-formula gift pack was negatively associated with any BF at all time points and with exclusive BF at 1 mo. Each additional BF-friendly hospital practice experienced was associated with 47% to 85% higher odds of any BF over the first 5 mo and 31% to 36% higher odds of exclusive BF over the first 3 mo. CONCLUSIONS: Exposure to BF-friendly hospital practices was associated with BF beyond the hospital stay. Expanding BF-friendly policies at the hospital could increase BF rates in the United States WIC-served population.

RESUMO

Gaining excessive gestational weight may increase obesity risk in the offspring, while breastfeeding lowers that risk. Using data from the Special Supplemental Nutrition Programme for Women, Infants and Children (WIC) in Southern California, we examined the associations between gestational weight gain (GWG), breastfeeding during infancy and childhood obesity at 2-4 years, and determined whether breastfeeding moderated the association between GWG and childhood obesity. GWG was based on weight measurements collected during the first trimester and within a month before delivery. GWG values were standardized by gestational age (GWG z-scores), per maternal prepregnancy body mass index (BMI) and categorized into tertiles. Fully breastfeeding duration was determined by WIC infant package data indicating the amount of infant formula received monthly. Children's length (or height) and weight measurements were used to calculate BMI-for-age z-scores and identify obesity (z-score ≥ 95th percentile). Multivariable linear and modified Poisson regression analyses were conducted. Fully breastfeeding moderated the association between GWG z-scores tertile and obesity in the offspring. Each additional month of fully breastfeeding was associated with 3%-5% obesity risk reduction for each age group and GWG z-scores tertile, except at age 4 years for children whose mothers had low GWG z-scores (tertile 1). Shorter fully breastfeeding duration was associated with greater obesity risk among children of mothers with high GWG z-scores (tertile 3), but not for those whose mothers had low GWG z-scores. Longer fully breastfeeding duration may provide greater protection against obesity among children at higher risk due to intrauterine exposure to high gestational weight gain.

RESUMO

OBJECTIVE: To evaluate the effectiveness of PASOS SALUDABLES, a culturally tailored lifestyle intervention to prevent obesity and diabetes among Latino farmworkers, when implemented at large scale in the worksite. DESIGN: This study was a two-arm parallel group, cluster randomised controlled trial, where participants received either a twelve-session lifestyle intervention (intervention) or six-session leadership training (control) at their worksite. The intervention was delivered by Promotoras in Spanish. All sessions were conducted at the worksites (ranches) during meal breaks. Blinded, trained research assistants collected socio-demographic and outcome data (i.e. BMI as primary outcome and waist circumference, glycated Hb (HbA1c), cholesterol and blood pressure as secondary outcomes) at baseline and follow-up assessments (i.e. 3 months, 6 months, 1 year and 1·5 years). SETTING: Recruitment and intervention delivery occurred at twelve study ranches in Oxnard, California. PARTICIPANTS: We enrolled farmworkers hired by a large berry grower company, who were ≥18 years old, spoke Spanish and were free of diabetes at screening. RESULTS: A total of 344 workers were enrolled in the intervention and 271 in the control group. The intervention resulted in attenuated increase of BMI over time; however, the difference in trend between groups was not significant (ß = -0·01 for slope difference, P = 0·29). No significantly different trend by group was observed in secondary outcomes (P > 0·27). CONCLUSIONS: The worksite intervention, implemented during meal breaks, did not reduce BMI or other clinical indicators. Nevertheless, this study supports the feasibility of recruiting and engaging the Latino farmworker population in workplace health promotion interventions.

RESUMO

Pregnancy and breastfeeding make demands on maternal nutrient stores. The extent of depletion and the degree to which nutrient stores are replenished between pregnancies has implications for a mother's nutritional status at conception of the subsequent child and therefore that child's birth outcomes and growth. Using follow-up data collected several years after a randomized effectiveness trial conducted in rural Bangladesh and a randomized efficacy trial conducted in semiurban Ghana, we evaluated the impact of maternal supplementation with small-quantity lipid-based nutrient supplements (LNS) or multiple micronutrients (MMN) through pregnancy (the index pregnancy) and 6 months postpartum on the growth status of the next living younger sibling conceived and born after the index pregnancy. In both Bangladesh (n = 472 younger siblings) and Ghana (n = 327 younger siblings), there were no overall differences in the growth status or the prevalence of undernutrition among younger siblings whose mothers had received LNS (or MMN, Ghana only) during and after the index pregnancy compared with the younger siblings of mothers who had received iron plus folic acid (IFA) during the index pregnancy (Ghana) or during and for 3 months after the index pregnancy (Bangladesh). These findings do not indicate that preconception nutrition interventions do not improve child growth. Rather, they suggest that any benefits of maternal LNS or MMN supplementation during one pregnancy and for 6 months postpartum are unlikely to extend to the growth of her next child beyond any effects due to IFA alone.

RESUMO

BACKGROUND: Nutritional interventions may affect child morbidity. OBJECTIVE: The aim of this study was to examine whether providing lipid-based nutrient supplements (LNSs) to pregnant and lactating women or LNS or micronutrient powder (MNP) to their infants influences child morbidity. METHODS: In a 4-arm cluster-randomized effectiveness trial, participants enrolled at ≤20 weeks of gestation (n = 4011) received: 1) maternal LNSs until 6 mo postpartum and child LNSs from 6-24 mo of age (LNS-LNS); 2) iron and folic acid (IFA) until 3 mo postpartum and child LNSs at 6-24 mo (IFA-LNS); 3) IFA (as above) and child MNP at 6-24 mo (IFA-MNP); or 4) IFA and no child supplement (IFA-Control). At 6, 12, 18, and 24 mo of age, we collected information on acute lower and upper respiratory infection (ALRI/AURI), diarrhea, and fever in the previous 14 d, and on episodes of illness in the previous 6 mo. RESULTS: At 6 mo, prevalence of ALRI, fever, or diarrhea in the previous 14 d (17.6%, 18.9% and 6.8%, respectively) did not differ between infants of women who received LNS and infants of women who received IFA, but prevalence of AURI was lower in the LNS-LNS group than in all other groups combined (27.7% compared with 31.7%; OR: 0.83; 95% CI: 0.70, 0.99). At 12, 18, and 24 mo, the 4 arms did not differ in prevalence of fever (∼18.3%) or ALRI (≤15%) in the previous 14 d, but prevalence of AURI at 12 mo was lower in IFA-LNS than in IFA-Control infants (27.6% compared with 33.9%, OR: 0.74; 95% CI: 0.56, 0.99). The mean ± SD number of diarrhea episodes in the previous 6 mo was significantly higher among IFA-LNS than among IFA-Control infants at 6-12 (0.46 ± 0.04 compared with 0.33 ± 0.03) and 12-18 (0.45 ± 0.03 compared with 0.33 ± 0.02) mo. No other pairwise group differences were significant. CONCLUSION: Providing LNSs to women or LNSs or MNP to children generally did not increase or decrease childhood illnesses. This trial was registered at clinicaltrials.gov as NCT01715038.

RESUMO

BACKGROUND: Diarrhea and acute respiratory infection (ARI) are major causes of child mortality. We aimed to identify risk factors associated with diarrhea and ARI among children under 2 years of age in rural northern Bangladesh. METHOD: We collected information on diarrhea and ARI in the previous 14 days and the previous 6 months at 6, 12, 18 and 24 months of age as part of a longitudinal, cluster randomized effectiveness trial, the Rang-Din Nutrition Study which enrolled 4011 pregnant women at ≤20 gestational weeks. Women and their children were followed up until 2 years postpartum. Information on household socioeconomic status, type of toilet, garbage disposal system, food insecurity, number of under-five children in the household, type of family, maternal characteristics and child characteristics was collected at baseline and/or at 6, 12, 18 and 24 months postpartum. Data on newborn health and feeding behaviors were collected within 72 h of delivery. Associations between potential risk factors and morbidity prevalence outcomes were assessed using logistic regression controlling for potential confounders. RESULTS: Out of 3664 live born children, we collected information from ~ 3350 children at 6, 12, 18 and 24 months of age. Diarrhea in the previous 14 days, and in the previous 6 months, was associated with maternal depression score and food insecurity; diarrhea in the previous 6 months was also associated with family type (nuclear vs. joint). ARI in the previous 14 days was associated with maternal depression score, type of toilet and garbage disposal, household food insecurity and sex. Cough or nasal discharge in the past 6 months was associated with maternal depression score, type of toilet and garbage disposal, household food insecurity, sex and perceived overall physical condition of the infant after birth. CONCLUSION: Maternal depression and food insecurity appear to be important risk factors for diarrhea and respiratory infection among children under 2 years of age in this setting. These findings suggest that policies and programs that include strategies to address maternal mental health and household food insecurity may contribute to improved child health. TRIAL REGISTRATION: The trial was registered with the US National Institutes of Health at ClinicalTrials.gov, # NCT01715038 , with registration completed October 26, 2012.

RESUMO

Low gestational weight gain (GWG) is a known predictor of fetal growth restriction in higher income countries, but there is little information on this association in lower income countries. Our objective is to describe the association between GWG and birth outcomes among pregnant women in rural Bangladesh. Pregnant women were identified in a community-based programme and enrolled into the study at an average of 13 weeks' gestation (n = 4,011). Maternal weight and height were measured at enrolment, maternal weight was measured at 36 weeks' gestation, and newborns were measured after birth. Rate of GWG (g/weeks) was calculated, and women were categorized as having adequate or inadequate GWG (Institute of Medicine recommendations). Newborn anthropometric outcomes included weight-for-age z score (WAZ), length-for-age z score (LAZ), head-circumference-for-age z score (HCZ), body mass index (BMI)-for-age z score (BMIZ), low birthweight (LBW < 2,500 g), WAZ < -2, LAZ < -2, HCZ < -2, BMIZ < -2, and small for gestational age (SGA: <10th percentile). Multivariate models were adjusted for confounders. Only 26% of the 2,562 women in these analyses had adequate GWG. Compared with newborns of women with inadequate GWG, infants of women with adequate GWG had a lower risk of adverse anthropometric outcomes (relative risk [95% confidence interval]: LBW = 0.68 [0.59, 0.80], LAZ < -2 = 0.64 [0.51, 0.80], HCZ < -2 = 0.75 [0.60, 0.93], BMIZ < -2 = 0.70 [0.59, 0.83], and SGA = 0.80 [0.73, 0.86]), but there was no significant difference in mean (SE) duration of gestation, 39.7 (0.08) versus 39.7 (0.05) weeks. In this population, GWG rate is a strong predictor of newborn anthropometric outcomes, but not duration of gestation.

RESUMO

Prenatal nutritional supplements may improve birth outcomes. This study aims to examine the effect of prenatal lipid-based nutrient supplements (LNS), compared with iron and folic acid (IFA), on general newborn physical condition and feeding behaviours. We conducted a cluster-randomized effectiveness trial that enrolled 4,011 pregnant women at ≤20 gestational weeks. LNS and IFA were provided to women in 48 and 16 clusters, respectively, for daily consumption until delivery. We collected data on household socio-economic, food insecurity, and maternal characteristics during early pregnancy and on newborn condition and feeding within 72 hr of delivery. We analysed intervention effects on these secondary outcomes using mixed models with analysis of covariance for continuous outcomes and logistic regression for dichotomous outcomes. Among 3,664 live births, intervention groups did not differ in newborn response, mother's rating of the general condition of her newborn, early initiation of breastfeeding (EIBF), suckling ability, or frequency and exclusivity of breastfeeding in the first 24 hr. If the mother perceived her infant to be healthy, EIBF was more likely (OR [95% CI]: 2.08 [1.46, 2.97]) and frequency of breastfeeding in the first 24 hr was greater (mean difference [95% CI]: 3.0 [1.91, 4.01]), but there was no difference in exclusive breastfeeding in the first 24 hr. Newborn condition and early breastfeeding practices were not affected by giving mothers prenatal LNS versus IFA. However, early breastfeeding practices were related to maternal perception of her newborn's condition. Thus, interventions to improve breastfeeding practices for newborns with poorer perceived health status may be useful.

RESUMO

Background: Maternal anemia and iron deficiency are prevalent in low- and middle-income countries. Objective: We aimed to determine the effects of lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) on hemoglobin (Hb), anemia, and iron status (nonprimary outcomes) at 36 weeks of gestation (women) and 6 mo postpartum (women and infants). Methods: The Rang-Din Nutrition Study, a cluster-randomized effectiveness trial, enrolled 4011 Bangladeshi pregnant women at ≤20 weeks of gestation to receive either daily LNS-PL (20 mg Fe) during pregnancy and the first 6 mo postpartum, or iron and folic acid (IFA, 60 mg Fe + 400 µg folic acid) daily during pregnancy and every other day during the first 3 mo postpartum. Biochemical measurements from a subsample of women (n = 1128) and their infants (n = 1117) included Hb (g/L), serum ferritin (µg/L), and soluble transferrin receptor (sTfR; mg/L). Anemia was defined as maternal Hb <110 g/L at 36 weeks of gestation, <120 g/L at 6 mo postpartum, or infant Hb <105 g/L; iron deficiency (ID) was defined as ferritin <12 µg/L or elevated sTfR (>8.3 mg/L for women and >11 mg/L for infants). Results: Compared with the IFA group, women in the LNS-PL group had lower ferritin (-6.2 µg/L; P < 0.001) and higher sTfR concentrations (+0.5 mg/L; P < 0.001), and higher risk of ID (OR = 1.93; P < 0.05) at 36 weeks of gestation but not at 6 mo postpartum, whereas no consistent differences were observed for Hb or anemia. Among infants at 6 mo, there were no group differences except for a lower risk of elevated sTfR (OR = 0.61; P < 0.05) in the LNS-PL group than in the IFA group. Conclusions: Provision of LNS-PL including a lower dose of iron than what is recommended during pregnancy resulted in differences in maternal iron status in late pregnancy that disappeared by 6 mo postpartum, and caused no undesirable effects regarding anemia or iron status of infants. This trial was registered at clinicaltrials.gov as NCT01715038.

RESUMO

Background: Anemia, iron deficiency (ID), and iron deficiency anemia (IDA) among young children are public health concerns in developing countries. Objective: We evaluated the effects of small-quantity lipid-based nutrient supplements (LNSs) and micronutrient powder (MNP) on anemia, ID, and IDA in 18-mo-old Bangladeshi children. Methods: We enrolled 4011 pregnant women in a cluster-randomized effectiveness trial with 4 arms-1) LNS-LNS: LNSs (including 20 mg Fe) for women daily during pregnancy and 6 mo postpartum and LNSs (including 9 mg Fe) for children daily from 6 to 24 mo of age (LNS-C); 2) IFA-LNS: iron (60 mg) and folic acid (IFA) for women daily during pregnancy and every other day for 3 mo postpartum and LNS-C for children; 3) IFA-MNP: IFA for women, and MNP (including 10 mg Fe) for children daily from 6 to 24 mo; and 4) IFA-Control: IFA for women and no child supplement. Hemoglobin, serum ferritin, and soluble transferrin receptor (sTfR) were assessed in a subsample of children (n = 1121) at 18 mo to identify anemia (hemoglobin <110g/L), ID (ferritin <12 µg/L or sTfR >8.3 mg/L), and IDA. Data were analyzed with the use of mixed-effects modeling. Results: Compared with the IFA-Control arm, hemoglobin was higher in the LNS-LNS and IFA-LNS arms and ferritin was higher and sTfR was lower in the LNS-LNS, IFA-LNS, and IFA-MNP arms; LNS-LNS children had reduced odds of anemia (OR: 0.46; 95% CI: 0.25, 0.84), high sTfR (OR: 0.47; 95% CI: 0.29, 0.73), and ID (OR: 0.45; 95% CI: 0.28, 0.71); and all 3 groups had lower odds of low ferritin [corrected for inflammation; OR (95% CI)-LNS-LNS: 0.29 (0.13, 0.63); IFA-LNS: 0.25 (0.11, 0.59); and IFA-MNP: 0.37 (0.18, 0.76)] and IDA [LNS-LNS: 0.35 (0.18, 0.67); IFA-LNS: 0.45 (0.24,0.85); and IFA-MNP: 0.47 (0.26, 0.87)]. Conclusions: Home fortification using LNSs or MNP reduced IDA in 18-mo-old Bangladeshi children. The provision of LNSs in both pregnancy and childhood also reduced child anemia and ID. These findings are relevant to programs targeting similar populations. This trial was registered at www.clinicaltrials.gov as NCT01715038.

RESUMO

Background: Pregnancy and childbirth complications and cesarean delivery are common in Bangladesh.Objective: We evaluated the effect of lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) on pregnancy and childbirth complications and cesarean delivery.Methods: We conducted the Rang-Din Nutrition Study, a cluster-randomized controlled effectiveness trial within a community health program in rural Bangladesh. We enrolled 4011 pregnant women in early pregnancy. Women in 48 clusters received iron and folic acid (IFA; 60 mg Fe + 400 µg folic acid/d) and women in 16 clusters received LNS-PL (20 g/d, 118 kcal) containing essential fatty acids and 22 vitamins and minerals. Pregnancy and childbirth complications and the cesarean delivery rate were secondary outcomes of the study.Results: Women in the LNS-PL group did not differ significantly from the IFA group with respect to mean systolic blood pressure at 36 wk gestation (113 and 112 mm Hg; P = 0.17), diastolic blood pressure at 36 wk gestation (68.9 and 68.7 mmHg; P = 0.88), or mean total number of pregnancy and childbirth complications (0.32 and 0.31; P = 0.86). They also did not differ significantly with respect to the prevalence of high blood pressure at 36 wk (1.74% and 2.03%; P = 0.62), antepartum hemorrhage (0.83% and 1.39%; P = 0.21), prolonged labor (8.34% and 8.79%; P = 0.68), early rupture of membranes (9.30% and 8.45%; P = 0.43), convulsions (1.57% and 1.08%; P = 0.24), high blood pressure in labor (1.54% and 1.19%; P = 0.46), obstructed labor (2.83% and 2.91%; P = 0.90), any complications during pregnancy or childbirth (35.9% and 37.1%; P = 0.64), episiotomy (6.31% and 6.44%; P = 0.90), or cesarean delivery (15.6% and 14.2%; P = 0.48).Conclusion: Compared with IFA, antenatal LNS-PL did not increase or decrease pregnancy and childbirth complications or cesarean delivery among women in rural Bangladesh. This trial was registered at clinicaltrials.gov as NCT01715038.

RESUMO

Background: Maternal iodine deficiency during pregnancy and lactation is common in Bangladesh.Objective: We evaluated the effect of lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) on urinary iodine concentration (UIC).Methods: We conducted a cluster-randomized controlled effectiveness trial in which we enrolled 4011 pregnant women at ≤20 gestational weeks. Women in 48 clusters received iron and folic acid (IFA; 60 mg Fe/d + 400 µg folic acid/d) and women in 16 clusters received LNS-PL (20 g/d, 118 kcal) containing 22 vitamins and minerals (including 250 µg I). We randomly selected a subsample of 1159 women for repeated urine sample collection, i.e., at enrollment, at 36 wk of gestation, and at 6 mo postpartum, for UIC analysis, a secondary outcome of the trial.Results: The geometric mean UIC at 36 wk of gestation and at 6 mo postpartum did not differ significantly between the IFA and LNS-PL groups. The median (quartile 1, quartile 3) UIC at 36 wk was 27.4 µg/L (16.9, 52.7 µg/L) in the IFA group and 30.2 µg/L (17.7, 56.6 µg/L) in the LNS-PL group; at 6 mo, these were 23.0 µg/L (10.0, 45.9 µg/L) in the IFA group and 22.2 µg/L (9.1, 50.4 µg/L) in the LNS-PL group.Conclusion: Daily consumption of LNS-PL containing 250 µg I did not increase the UICs of pregnant and lactating women in Bangladesh. Iodine from lipid-based nutrient supplements may have been stored in the thyroid gland or secreted in breast milk instead of being excreted in urine. Additional research that uses other biomarkers of iodine status is needed to determine how to meet the iodine requirements of pregnant and lactating women in Bangladesh and similar settings. This trial was registered at clinicaltrials.gov as NCT01715038.

RESUMO

Background: It is unknown whether self-reported measures of household food insecurity change in response to food-based nutrient supplementation.Objective: We assessed the impacts of providing lipid-based nutrient supplements (LNSs) to women during pregnancy and postpartum and/or to their children on self-reported household food insecurity in Malawi [DOSE and DYAD trial in Malawi (DYAD-M)], Ghana [DYAD trial in Ghana (DYAD-G)], and Bangladesh [Rang-Din Nutrition Study (RDNS) trial].Methods: Longitudinal household food-insecurity data were collected during 3 individually randomized trials and 1 cluster-randomized trial testing the efficacy or effectiveness of LNSs (generally 118 kcal/d). Seasonally adjusted Household Food Insecurity Access Scale (HFIAS) scores were constructed for 1127 DOSE households, 732 DYAD-M households, 1109 DYAD-G households, and 3671 RDNS households. The impact of providing LNSs to women during pregnancy and the first 6 mo postpartum and/or to their children from 6 to 18-24 mo on seasonally adjusted HFIAS scores was assessed by using negative binomial models (DOSE, DYAD-M, and DYAD-G trials) and mixed-effect negative binomial models (RDNS trial).Results: In the DOSE and DYAD-G trials, seasonally adjusted HFIAS scores were not different between the LNS and non-LNS groups. In the DYAD-M trial, the average household food-insecurity scores were 14% lower (P = 0.01) in LNS households than in non-LNS households. In the RDNS trial, compared with non-LNS households, food-insecurity scores were 17% lower (P = 0.02) during pregnancy and the first 6 mo postpartum and 15% lower (P = 0.02) at 6-24 mo postpartum in LNS households.Conclusions: The daily provision of LNSs to mothers and their children throughout much of the "first 1000 d" may improve household food security in some settings, which could be viewed as an additional benefit that may accrue in households should policy makers choose to invest in LNSs to promote child growth and development. These trials were registered at clinicaltrials.gov as NCT00945698 (DOSE) NCT01239693 (DYAD-M), NCT00970866 (DYAD-G) and NCT01715038 (RDNS).

RESUMO

OBJECTIVE: To determine the effects of lipid-based nutrient supplements (LNS) on children's Hb, linear growth and development, compared with supplementation with micronutrient powder (MNP). DESIGN: The study was a two-arm parallel-group randomized controlled trial, where participants received either LNS or MNP for daily consumption during 6 months. Supplements were delivered by staff at government-run health centres. Hb, anthropometric, motor development, language development and problem-solving indicators were measured by trained research assistants when children were 12 months of age. SETTING: The study was conducted in five rural districts in the Province of Ambo in the Department of Huánuco, Peru. SUBJECTS: We enrolled 6-month-old children (n 422) at nineteen health centres. RESULTS: Children who received LNS had a higher mean Hb concentration and lower odds of anaemia than those who received MNP. No significant differences in height-for-age, weight-for-height or weight-for-age Z-score, or stunting and underweight prevalence, were observed. Provision of LNS was associated with a higher pre-verbal language (gestures) score, but such effect lost significance after adjustment for covariates. Children in the LNS group had higher problem-solving task scores and increased odds of achieving this cognitive task than children in the MNP group. No significant differences were observed on receptive language or gross motor development. CONCLUSIONS: LNS between 6 and 12 months of age increased Hb concentration, reduced anaemia and improved cognitive development in children, but showed no effects on anthropometric indicators, motor or language development.

RESUMO

OBJECTIVE: To: (i) determine the prevalence of self-reported eating less and eating down during early and late pregnancy and postpartum, and explore risk factors associated with eating less; (ii) examine the association between eating less and diet quality; and (iii) determine the association between eating less and weight gain during pregnancy. DESIGN: Data were collected longitudinally from a cohort of women participating in a community health programme. Diet was assessed at three time points (≤20 weeks' gestation, 36 weeks' gestation, 6 months' postpartum), body weight was measured during study enrolment (≤20 weeks' gestation) and at 36 weeks' gestation, and information about the woman and her household was collected at enrolment. SETTING: The Rang-Din Nutrition Study in the Rangpur and Dinajpur districts of Bangladesh. SUBJECTS: Women (n 4011). RESULTS: The prevalence of self-reported eating less differed by time point (75·9 % in early pregnancy, 38·8 % in late pregnancy, 7·4 % postpartum; P<0·001). The most common reason for eating less across all time periods was food aversion or loss of appetite. Women who reported eating less in late pregnancy had consumed animal-source foods less frequently in the preceding week than women who reported eating more (mean (sd): 11·7 (7·4) v. 14·8 (9·2) times/week; P<0·001) and had lower weekly weight gain than women who reported eating more (mean (se): 0·27 (0·004) v. 0·33 (0·004) kg/week; P<0·001). CONCLUSIONS: Eating less has negative implications with respect to diet quality and pregnancy weight gain in this context.

RESUMO

Limited knowledge exists on sustained adherence to small-quantity lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) and how this compares with that of other prenatal supplements. To address these gaps, a random subsample of women (n = 360) during pregnancy, early (6- to 12-week post-partum) and late (12- to 24-week post-partum) lactation, from an ongoing effectiveness trial in Bangladesh, was selected for in-home interviews about LNS-PL or iron/folic acid (IFA) use and preferences. Prevalence of high adherence (≥70% of the recommendation) based on self-reported supplement consumption was 67%, 68% and 81% among LNS-PL recipients during pregnancy, early and late lactation, and was 87% and 71% among IFA recipients during pregnancy and early lactation, respectively (P = 0.044). Programmatic factors (e.g. distribution and visits by programme staff) were consistently statistically significantly associated with reported high adherence. Among LNS-PL recipients, high overall supplement acceptability score [odds ratio (OR): 8.62; 95% confidence interval (CI) 3.53, 20.83] and use of reminder techniques (OR: 4.41; 95%CI 1.65, 11.76) were positively associated, and reported vomiting at enrollment was negatively associated (OR: 0.34; 95%CI 0.14, 0.80), with reported high adherence. Selected women (n = 16) and key informants (n = 18) participated in in-depth interviews about perceptions and acceptability of LNS-PL. Women perceived benefits of taking LNS-PL, but some faced barriers to consumption including aversion to odour and taste during pregnancy, forgetfulness and disruptions in supply. To achieve high adherence, results from this study suggest that maternal supplementation programmes should focus on programmatic barriers and consider incorporating reminder techniques. Organoleptic acceptability of LNS-PL, particularly during pregnancy, may also need to be addressed.

RESUMO

BACKGROUND: Maternal undernutrition and low macro- and micronutrient intake and weight gain during pregnancy have been reported in Bangladesh. OBJECTIVE: We aimed to determine the effects of lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) on weight gain and midupper arm circumference (MUAC) during pregnancy. METHODS: The Rang-Din Nutrition Study, a cluster-randomized effectiveness trial conducted in Bangladesh, enrolled 4011 pregnant women at ≤20 wk gestation who received either 60 mg Fe + 400 µg folic acid/d or 20 g LNS-PL/d (118 kcal) containing essential fatty acids and vitamins and minerals until delivery. At 36 wk gestation, women were interviewed at home and then attended a follow-up examination at local clinics (n = 2877), where anthropometric measurements were taken. RESULTS: No significant differences between intervention groups in maternal weight gain per week, low weight gain per week, or MUAC at 36 wk gestation were observed in the full sample. However, among multiparous women aged ≥25 y, those in the LNS-PL group gained 34 g/wk more than their counterparts in the iron and folic acid (IFA) group (P = 0.001), whereas no differences were seen in the other parity/age subgroups. Women aged ≥25 y in the LNS-PL group had a 0.4-cm greater MUAC than their counterparts in the IFA group (P = 0.003); no significant differences were observed in the other age groups. Among women whose height at baseline was in the lowest quartile of the distribution, those in the LNS-PL group had a 0.1-0.3-cm greater MUAC at 36 wk gestation than those in the IFA group (P = 0.004-0.014). CONCLUSIONS: Lipid-based nutrient supplements provided during pregnancy did not affect maternal anthropometric indicators in the overall sample but increased MUAC among women aged ≥25 y and those with lower stature and weight gain among multiparous women aged ≥25 y. This trial was registered at clinicaltrials.gov as NCT01715038.

RESUMO

College students may face barriers to eating healthy foods. Educational interventions providing practical knowledge and skills may help students to overcome financial barriers or other barriers to acquiring, preparing, and consuming healthy foods. We evaluated the association between participation in a semester-long food skills course with an interactive teaching kitchen and dietary and cooking self-efficacy and behaviors. Participants were recruited from course enrollees (intervention) and the general student population (comparison). We assessed differences in pre-post changes in the outcomes between groups using the propensity score weighting and mixed effects linear or Poisson regression. Course participation was associated with improved self-efficacy around cooking (group × time ß-coefficient [SE]: 3.25 [0.57], p < 0.0001) and fruit (6.33 [1.19], p < 0.0001), vegetable (5.43 [1.42], p = 0.0002), and whole grain (5.83 [1.40], p < 0.0001) consumption. Course participants reported smaller pre-post decreases in vegetable consumption compared to non-participants (0.35 [0.16], p = 0.03), increased cooking frequency (0.22 [0.10], p = 0.03) and a decreased frequency of skipping meals (-0.47 [0.16], p = 0.003). There were no changes associated with the intervention in the consumption of fruit or whole grains, or in eating out frequency. Participation in a semester-long, personal food skills course with a teaching kitchen may improve self-efficacy, cooking, and vegetable consumption among college students.

RESUMO

Introduction: The U.S. Child and Adult Care Food Program (CACFP) provides tiered reimbursements for healthy foods for children at participating family childcare homes (FCCH). Higher tier 1 reimbursements are for providers who operate in low-income communities or who are themselves living on a low income. All FCCHs received a higher rate to address food insecurity during the COVID-19 pandemic. Methods: A survey was administered in the spring of 2023 to a randomly selected sample of licensed California FCCHs to assess the perceived impacts of the increased reimbursement on CACFP participation and anticipated challenges with reinstated tiered rates. A total of 518 surveys (261 tier 1, 257 tier 2) were analyzed using linear or logistic regression, adjusting for confounders. Results: Among tier 1 and tier 2 providers combined, over half reported lowering out-of-pocket spending for food (59%) and serving greater variety (55%) and quality (54%) of foods. Tier 2 providers reported experiencing more benefits (p < 0.05) and tended to be more likely to implement optional CACFP best practices (although not significantly different between tiers). Most FCCH providers found reimbursement rates were inadequate before (83%) the pandemic; this amount decreased to 54% post-pandemic for tier 1 and tier 2 providers combined. Conclusions: The temporary CACFP reimbursement positively impacted the perceived quality and variety of foods served to children, especially among tier 2 providers. Increased reimbursements for all FCCHs may ensure children have access to the healthy meals and snacks provided by the CACFP.
