ABSTRACT

AIM: We examined household food insecurity (HFI) and autonomic nervous system (ANS) function in a subset of low-income Latinos with type 2 diabetes with data from a stress management trial. METHODS: InclusionLatino or Hispanic, Spanish speaking, age less than 18 years, ambulatory status, type 2 diabetes more than 6 months, A1c less than 7.0%. ExclusionPain or dysfunction in hands (e.g., arthritis) precluding handgrip testing; medical or psychiatric instability. HFI was assessed with the 6-item U.S. household food security survey module; with responses to > = 1 question considered HFI. An ANS dysfunction index was calculated from xix autonomic function tests which were scored 0 = normal or 1 = abnormal based on normative cutoffs and then summed. Autonomic function tests were: 1) 24-hour heart rate variability as reflected in standard deviation of the normal-to-normal (SDNN) heart rate acquired with 3-channel, 7-lead ambulatory electrocardiogram (Holter) monitors; 2) difference between the highest diastolic blood pressure (DBP) during sustained handgrip and the average DBP at rest; 3) difference between baseline supine and the minimal BP after standing up; and, from 24-hour urine specimens 4) cortisol, 5) normetanephrine, and, 6) metanephrine. RESULTS: Thirty-five individuals participated, 23 (65.7%) of them were women, age mean = 61.6 (standard deviation = 11.2) years, HbA1c mean = 8.5% (standard deviation = 1.6) and 20 participants (57.1%) used insulin. Twenty-two participants (62.9%) reported HFI and 25 (71.4%) had one or more abnormal ANS measure. Independent t-tests showed that participants with HFI had a higher ANS dysfunction index (mean = 1.5, standard deviation = 0.9) than patients who were food secure (mean = 0.7, standard deviation = 0.8), p = 0.02. Controlling for financial strain did not change significance. Total ANS index was not related to glycemia, insulin use or other socioeconomic indicators. In this sample, HFI was associated with ANS dysfunction. Policies to improve food access and affordability may benefit health outcomes for Latinos with diabetes.

ABSTRACT

Aims: The role of lay health workers in data collection for clinical and translational research studies is not well described. We explored lay health workers as data collectors in clinical and translational research studies. We also present several methods for examining their work, i.e., qualitative interviews, fidelity checklists, and rates of unusable/missing data. Methods: We conducted 2 randomized, controlled trials that employed lay health research personnel (LHR) who were employed by community-based organizations. In one study, n = 3 Latina LHRs worked with n = 107 Latino diabetic participants. In another study, n = 6 LHR worked with n = 188 Cambodian American refugees with depression. We investigated proficiency in biological, behavioral, and psychosocial home-based data collection conducted by LHR. We also conducted in-depth interviews with lay LHR to explore their experience in this research role. Finally, we described the training, supervision, and collaboration for LHR to be successful in their research role. Results: Independent observers reported a very high degree of fidelity to technical data collection protocols (>95%) and low rates of missing/unusable data (1.5%-11%). Qualitative results show that trust, training, communication, and supervision are key and that LHR report feeling empowered by their role. LHR training included various content areas over several weeks with special attention to LHR and participant safety. Training and supervision from both the academic researchers and the staff at the community-based organizations were necessary and had to be well-coordinated. Conclusions: Carefully selected, trained, and supervised LHRs can collect sophisticated data for community-based clinical and translational research.

ABSTRACT

BACKGROUND: Early feeding practices have a great impact on the growth and development of infants, and the health of mothers. Maternal emotional regulation (ER) is closely related to infant feeding practices. Exploring the relationship between ER strategy and feeding practice can inform early exclusive breastfeeding (EBF) interventions. METHODS: Using baseline survey of a longitudinal study, 965 mothers in Chongqing municipality, Guangzhou city, and Huizhou city were enrolled. At baseline, the study used self-administrated questionnaires to investigate the socio-demographic characteristics, maternal ER strategies and feeding practice within 72 h of delivery. Chi-square test and logistic regression were used to determine the associations of the mothers' ER and feeding practices within 72 h postpartum. RESULTS: Among 965 participants, 27.8 % of mothers practiced EBF, and 69.5 % of mothers reported getting breastfeeding education from health providers. The average scores on the cognitive reappraisal and the expressive suppression of the ERQ were 29.95 ± 7.24 and 14.47 ± 5.16 respectively. Multivariable analysis showed women with expressive suppression were less likely to practice EBF (aOR = 0.96, 95%CI: 0.93-0.98, p = 0.002), while receiving breastfeeding education was positively associated with EBF (aOR = 1.52, 95%CI: 1.09-2.12, p = 0.013). LIMITATIONS: Because the study started during the COVID-19 pandemic, the lock-down measures paused recruitments for quite some time reducing the enrollment of participation. The data we used was within 72 h postpartum, hence the period of time to study feeding practices was short. CONCLUSION: Mothers' ER strategy and breastfeeding education need to be addressed as part of interventions designed to improve EBF rates during the newborn period in China.

ABSTRACT

Background: Emergency cesarean section (EMCS) and breastfeeding difficulties increase the risk of postpartum depressive (PPD) symptoms. Early initiation of breastfeeding (EIBF) may not only alleviate PPD symptoms but also facilitate subsequent breastfeeding success. EMCS is a risk factor for not practicing EIBF. Therefore, it is important to understand the relationship between EMCS, EIBF, and PPD symptoms. Methods: We conducted a prospective cohort study in three areas of China. At baseline, a total of 965 mothers completed electronic questionnaires within 72 h postpartum. Women were screened for PPD symptoms using the Edinburgh Postpartum Depression Scale (EPDS). Multivariate logistic regression was used to identify the determinants of PPD symptoms. Mediation analysis was used to determine if EIBF mediated the relationship between delivery mode or breastfeeding education source and PPD symptoms. Results: The prevalence of EIBF was 40.6%; 14% of 965 mothers experienced EMCS, and 20.4% had PPD symptoms. The risk factors for developing PPD symptoms were excessive gestational weight gain (adjusted odds ratio [aOR] = 1.55, confidence interval [95% CI]: 1.03−2.33, p = 0.037) and EMCS (aOR = 2.05, 95% CI: 1.30−3.25, p = 0.002). The protective factors for developing PPD symptoms were monthly household income over CNY 10000 (aOR = 0.68, 95% CI: 0.47−0.97, p = 0.034), EIBF (aOR = 0.49, 95% CI: 0.34−0.72, p < 0.001), and prenatal breastfeeding education from nurses (aOR = 0.46, 95% CI: 0.29−0.73, p = 0.001). EIBF indirectly affected PPD symptoms in patients who had undergone EMCS (percentage mediated [PM] = 16.69, 95% CI: 7.85−25.25, p < 0.001). The source of breastfeeding education through EIBF also affected PPD symptoms (PM = 17.29, 95% CI: 3.80−30.78, p = 0.012). Conclusion: The association between EMCS on PPD symptoms was mediated by EIBF. By providing breastfeeding education, nurses could also help alleviate PPD symptoms.

ABSTRACT

OBJECTIVES: We explored associations between night eating and health outcomes in Latinos with type 2 diabetes. METHODS: Participants (n = 85) completed surveys, were measured for anthropometrics, provided blood samples, and wore Holter monitors for 24 hours to assess heart rate variability. RESULTS: Participant mean age was 60.0 years, hemoglobin A1c was 8.7%, most preferred Spanish (92%), and had less than a high school education (76%). Compared with their counterparts who denied night eating, night eaters had lower heart rate variability in the low (Cohen's d = -0.55; P = 0.04) and very-low-frequency bands (d = -0.54, P = 0.05), and reported more emotional eating (d = 0.52, P = 0.04), and poorer sleep quality (Cohen's h = 0.64). They did not differ on beverage intake or depressive symptoms. In regression that included depressive symptoms, associations between night eating and outcomes became nonsignificant. CONCLUSIONS AND IMPLICATIONS: Night eaters demonstrated worse health outcomes. If results are replicated, nutrition education for this population might focus on night eating.

ABSTRACT

Caregivers are often concerned about baby behaviours. Without adequate counselling, parental response can lead to altering infant feeding and jeopardizing breastfeeding. We conducted a systematic review to assess the evidence about the influence of baby behaviours perceived as problematic (crying, sleep waking and posseting) on infant feeding decisions during the first 6 months of life (self-reported milk insufficiency, breastfeeding duration and introduction of formula). The review focused on quantitative studies published in English, Portuguese or Spanish without date restriction. The search was designed with the support of a medical librarian and conducted in seven databases. Data were managed in Covidence and risk of bias was assessed through the Johanna Briggs Institute critical appraisal checklists. Synthesis of the literature was guided by a conceptual model of the impact of baby behaviours on caregivers feeding practices. We retrieved and reviewed 4312 titles/abstracts and selected 22 for review; 10 were purely descriptive and 12 were cross-sectional, prospective and quasi-experimental studies. Although studies from diverse regions were included in the review, more than half were from high-income countries. All studies reported that baby behaviours affect feeding decisions, the most common baby behaviours studied were crying and fussiness, and the studies suggested relationships with lactation problems and reports of milk insufficiency, maternal breastfeeding confidence, breastfeeding duration and discontinuation, and introduction of formula. There are many factors that lead to perceiving baby behaviours as problematic and there is a need to provide anticipatory guidance to parents and caregivers, starting in pregnancy and counselling through well-trained health providers.

ABSTRACT

Background: The United Nations Children's Fund (UNICEF) Community Infant and Young Child Feeding Counselling Package (C-IYCF CP) is used globally for infant and young child feeding (IYCF) counseling. With the C-IYCF CP last updated 8 y ago, mapping existing nurturing care content, identifying gaps, and documenting current country-level changes offers a unique opportunity to guide recommendations to strengthen the nurturing care content of this package. Objectives: The primary study aims were to: 1) identify and map existing nurturing care content within UNICEF's C-IYCF CP, 2) identify gaps related to nurturing care or feeding elements within the C-IYCF CP, 3) identify country-level nurturing care adaptations to the C-IYCF CP, and 4) identify best practices and lessons learned from country adaptations that can be recommended for inclusion in the C-IYCF CP. Methods: The assessment included 4 phases: 1) conduct an iterative process to identify and map nurturing care elements within the C-IYCF CP using a codebook explicitly developed for this assessment; 2) identify gaps in the C-IYCF CP; 3) apply the codebook to IYCF packages from 11 countries, revise, then finalize the codebook; and 4) identify and interview key informants from 4 countries whose IYCF packages had the most comprehensive nurturing care content plus 1 country where health care professionals make routine mother-child home visits. Results: The C-IYCF CP contained limited nurturing care content, especially around safety/security and early learning. All 5 countries interviewed had systematically identified and included priority nurturing care content in each package, yet content level varied. Two countries were also incorporating information technology into the training and delivery of the C-IYCF CP. Conclusions: Existing country-level best practices can address nurturing care elements missing from UNICEF's C-IYCF CP. Sharing these practices can allow countries to make context-driven, evidence-informed decisions on the nurturing care content to prioritize.

ABSTRACT

The introduction of fluids other than breast milk during the first few days of life or later neonatal period has been identified as a risk factor for suboptimal breastfeeding (BF) outcomes in numerous studies using varying study designs. However, the relationship between early introduction of fluids other than breast milk and BF outcomes has not been systematically assessed using only prospective studies that can establish temporality, which is critical for determining whether observed associations are causal. We conducted a systematic review and meta-analysis of prospective studies to assess if there is a difference in BF outcomes as a result of the introduction of: (a) milk-based prelacteals, (b) water-based prelacteals and (c) breast milk substitutes (BMS) between 4 days and 4 weeks postpartum. We searched PubMed, Lilacs, Web of Science and other repositories for original research investigating the relationship between early introduction of prelacteals and/or BMS and BF outcomes. Forty-eight studies met the inclusion criteria for the systematic review. Of the 39 prelacteal feeding studies, 27 had the prerequisite statistical information for inclusion in the meta-analysis. Findings from the meta-analysis showed a relationship between prelacteals and exclusive BF cessation (RR 1.44; 1.29-1.60) and any BF cessation (2.23; 1.63-3.06) among infants under 6 months old. Nine studies focusing on the introduction of BMS during the neonatal period identified this practice as a statistically significant risk factor for a shorter BF duration. Effective interventions are needed to prevent the introduction of unnecessary milk-based prelacteals and BMS during the perinatal and neonatal periods to improve BF outcomes.

ABSTRACT

The objective of this systematic review was to identify multifactorial risk factors for self-reported insufficient milk (SRIM) and delayed onset of lactation (DOL). The review protocol was registered a priori in PROSPERO (ID# CDR42021240413). Of the 120 studies included (98 on SRIM, 18 on DOL, and 4 both), 37 (31%) studies were conducted in North America, followed by 26 (21.6%) in Europe, 25 (21%) in East Asia, and Pacific, 15 (12.5%) in Latin America and the Caribbean, 7 (6%) in the Middle East and North Africa, 5 (4%) in South Asia, 3 (2.5%) in Sub-Saharan Africa, and 2 (1.7%) included multiple countries. A total of 79 studies were from high-income countries, 30 from upper-middle-income, 10 from low-middle-income countries, and one study was conducted in a high-income and an upper-middle-income country. Findings indicated that DOL increased the risk of SRIM. Protective factors identified for DOL and SRIM were hospital practices, such as timely breastfeeding (BF) initiation, avoiding in-hospital commercial milk formula supplementation, and BF counselling/support. By contrast, maternal overweight/obesity, caesarean section, and poor maternal physical and mental health were risk factors for DOL and SRIM. SRIM was associated with primiparity, the mother's interpretation of the baby's fussiness or crying, and low maternal BF self-efficacy. Biomedical factors including epidural anaesthesia and prolonged stage II labour were associated with DOL. Thus, to protect against SRIM and DOL it is key to prevent unnecessary caesarean sections, implement the Baby-Friendly Ten Steps at maternity facilities, and provide BF counselling that includes baby behaviours.

ABSTRACT

BACKGROUND: Socio-economic inequities can strongly influence suboptimal infant feeding outcomes. Factors such as lack of knowledge about breastfeeding, low family income, low educational attainment, social and economic status, cultural norms and ethnicity may negatively affect success with offering breastfeeding following a responsive feeding approach (ie. responsive breastfeeding). Such inequities can indeed shorten breastfeeding duration, and negatively affect behavioral and cognitive infant outcomes. In China, there is a dearth of studies focusing on breastfeeding from the responsive and health equity perspective. OBJECTIVE: The aim of this article is to present a protocol of an ongoing longitudinal cohort study investigating factors associated with responsive breastfeeding behaviors, and the child's behavioral and cognitive development from birth to12 months post-partum in five centers in China. The study seeks to identify breastfeeding barriers and facilitators from a health equity perspective. METHODS: We are enrolling 700 women and their singleton full term infants in Chongqing, Huizhou and Guangzhou urban and rural areas. The study questionnaires will be administrated within 72 h, 30 days, 3, 6, 9, and 12 months post-partum during the baby's vaccination visits. We will investigate the difference between urban and rural areas sociodemographic characteristics, breastfeeding knowledge, attitudes and practice, postnatal depression, maternal emotion regulation and parenting stress, and anthropometric and cognitive development indicators of the infants at each time-point. CONCLUSION: Our article illustrates how a cohort study can be designed to understand the barriers and facilitators of responsive breastfeeding taking equity principles into account to help promote infants' growth and development in China.

ABSTRACT

BACKGROUND: In the U.S., strong ethnic/racial, socioeconomic, demographic, and geographic breastfeeding (BF) inequities persist, and African American and Hispanic women are less likely to meet their breastfeeding goals compared to White women. This systematic review (SR) was designed to answer the question: What is the impact of breastfeeding interventions targeting ethnic/racial minority women in the U.S. on improving BF initiation, duration and exclusivity rates? METHODS: The SR was conducted following the Institute of Medicine Guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. The study protocol was developed and registered a priori in PROSPERO (ID#CRD42020177764). The electronical databases searched was MEDLINE All (Ovid). Search strategies were led by the team's expert public health librarian using both controlled vocabulary and free text queries and were tested against a validated set of relevant papers included in existing reviews. The GRADE methodology was used to assess the quality of the studies. RESULTS: We included 60 studies that had randomized (n = 25), observational (n = 24), quasi-experimental (n = 9), or cross-sectional (n = 2) designs. The studies focused on populations that were multi-ethnic/racial (n = 22), only Hispanic (n = 24), only Black (n = 13), and only American Indian (n = 1). The study interventions were classified following the socioecological model: macrosystem/policy level (n = 6); community level (n=51), which included healthcare organizations (n = 34), The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) (n = 9), and community organizations/public health institutions (n = 8); and  interpersonal level (n = 3). CONCLUSIONS: Policy and community level interventions delivered through WIC, healthcare facilities, and community agencies) are likely to improve BF outcomes among women of color. The combination of interventions at different levels of the socioecological model has not been studied among minority women in the U.S. Implementation science research is needed to learn how best to scale up and sustain effective BF interventions, taking into account the needs and wants of minority women. Thus, it is strongly recommended  to conduct large scale implementation research studies addressesing how to strengthen the different health and social environments surrounding women of color in the U.S. to improving their BF outcomes.

ABSTRACT

Responsive feeding (RF) has been recognized as necessary to prevent all forms of malnutrition including stunting and childhood obesity. Specific RF guidelines have been developed, but it is unclear how RF behaviours can be monitored systematically. Therefore, developing valid and reliable abbreviated and pragmatic RF scales is an important global priority. This is challenging, as RF is a construct with multiple dimensions including recognizing and responding to hunger and satiety cues, providing a nurturing environment during feeding episodes, and understanding how feeding needs evolve as a function of the developmental stage of the young child. Further, RF is embedded within the responsive parenting framework that in addition to RF includes sleep, soothing and play routines and the interconnections between them. A recent pioneer study conducted in a rural area of Cambodia validated an 8-item RF scale through direct feeding observations of 6- to 23-month-old infants at home, as part of two cross-sectional surveys conducted before and after a complementary feeding intervention. It is important for similar research to be conducted elsewhere to find out if it is possible or not to develop a core RF scale that is valid and reliable and that has adequate specificity and sensitivity for application in community studies and population surveys globally. As highlighted in this article, different definitions of RF have been used in the field; thus, it is important to reach consensus on a single definition to help move this research area forward.

ABSTRACT

Dietary guidelines provide advice on what to eat to different subsets of the population but often do not take into account the "how" to eat. Responsive feeding is a key dimension of responsive parenting involving reciprocity between the child and caregiver during the feeding process and is characterized by caregiver guidance and recognition of the child's cues of hunger and satiety. Evidence indicates that providing responsive feeding guidance to mothers on how to recognize and respond appropriately to children's hunger and satiety cues can lead to improved feeding practices and weight status and developmental outcomes among infants and young children. In addition, early and nurturing exposures to foods with different tastes and textures and positive role modelling help children to learn to eat healthy foods. The importance of improving caregiver's responsive feeding behaviours to ensure the adequate introduction of complementary foods is becoming increasing recognized, but responsive feeding principles have not been taken into account in a comprehensive way in the development of dietary guidelines. The incorporation of all responsive feeding principles into dietary guidelines has a strong potential to enhance their impact on early childhood development outcomes for infants and young children but will require adaptation to the different contexts across countries to ensure that they are culturally sensitive and grounded in a deep understanding of the types of foods and other resources available to diverse communities.

ABSTRACT

The WHO recommends exclusive breastfeeding of infants for the first 6 mo of life (EBF-6). We reviewed the evidence behind concerns related to this recommendation. The risk of iron deficiency among EBF-6 infants can be significantly reduced if delayed cord clamping is performed in all newborns. At the moment there is no population-level evidence indicating that exclusive breastfeeding for 6 mo compared with <6 mo increases the risk of developing food allergies. Mild to moderate maternal undernutrition may reduce amounts of some nutrients in breast milk but does not directly diminish milk volume. Persistent reports of insufficient milk by women globally are likely to be the result of lack of access to timely lactation counseling and social support rather than primary biological reasons. All newborns should have their growth, hydration status, and development carefully monitored. In instances where formula supplementation is required, it should be done under the guidance of a qualified provider taking into account that early introduction of breast-milk supplements is a risk factor for early termination of exclusive breastfeeding and any breastfeeding. We found no evidence to support changes to the EBF-6 public health recommendation, although variability in inter-infant developmental readiness is recognized. We suggest that infant and young feeding guidelines make clear that complementary foods should be introduced at around 6 mo of age, taking infant developmental readiness into account.

ABSTRACT

BACKGROUND: Household food insecurity (HFI) is a stressor that is associated with type 2 diabetes (T2D). However, little is known about HFI and the insulin resistance (IR) underlying T2D, and the mechanisms involved. OBJECTIVE: We examined the cross-sectional association between HFI and IR among low-income Latinos with T2D and tested whether inflammation and stress hormones mediated this association. METHODS: HFI was measured with the 6-item US Household Food Security Survey module. IR was calculated from fasting plasma blood glucose and serum insulin. Inflammation was indicated by high-sensitivity C-reactive protein (hsCRP), and stress hormones included urinary cortisol, metanephrine, and normetanephrine. To test for an indirect effect of HFI on homeostasis model assessment of IR, a parallel multiple mediation model was run with biological markers that significantly differed between food security status-entered as mediators in the model. We used 95% bias-corrected bootstrap CIs, with 10,000 bootstrap samples, to assess the significance of the indirect effects. RESULTS: The 121 participants with T2D were primarily Puerto Rican (85.8%), aged mean = 60.7 y, and 74% were female. Eighty-two (68%) were classified as food insecure. Compared with food-secure individuals, food-insecure individuals had a significantly higher IR [mean difference (Δ) = 7.21, P = 0.001], insulin (Δ = 9.7, P = 0.019), glucose (Δ = 41, P < 0.001), hsCRP (Δ = 0.8, P = 0.008), cortisol (Δ = 21, P = 0.045), and total cholesterol (Δ = 29, P = 0.004). Groups did not differ on other lipids, metanephrine, normetanephrine, or A1c. The mediation model showed a significant direct effect of HFI on hsCRP (P = 0.020) and on cortisol (P = 0.011). There was a direct effect of cortisol (P = 0.013), hsCRP (P = 0.044), and HFI on IR (P = 0.015). The total combined indirect effect of HFI through cortisol and hsCRP indicated partial mediation. CONCLUSIONS: Among Latinos with T2D, HFI is associated with IR partially through inflammation and stress hormones. Interventions to ameliorate HFI and mitigate its effects on inflammation, stress, and IR are warranted. This trial was registered at clinicaltrials.gov as NCT01578096.

ABSTRACT

OBJECTIVE: Determine the impact of a 2-way text messaging intervention on time to contact between participants and their breastfeeding peer counselors (BFPCs) and on exclusive breastfeeding (EBF) status at 2 weeks and 3 months postpartum. DESIGN: Multisite, single-blind, randomized, controlled trial. SETTING: Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) BFPC program. PARTICIPANTS: Low-income women (n = 174) participating in the WIC BFPC program. INTERVENTION: The control group received the standard of care WIC Loving Support BFPC program. The intervention group received standard of care plus the text messaging intervention. MAIN OUTCOME MEASURES: Time to contact with BFPC and EBF status. ANALYSIS: The 2-sample t test or χ2 test assessed whether an association existed between study variables and each outcome. Multivariable ordinal and binary logistic regression assessed the impact of the intervention on time to contact and EBF status. RESULTS: Lactation Advice Through Texting Can Help had a significant impact on early contact between participants and BFPCs (odds ratio = 2.93; 95% confidence interval, 1.35-6.37) but did not have a significant impact on EBF (odds ratio = 1.26; 95% confidence interval, 0.54-2.66). CONCLUSIONS AND IMPLICATIONS: Lactation Advice Through Texting Can Help has the potential to facilitate the work of BFPCs by shortening the time-to-first-contact with clients after giving birth. Research is needed to identify the level of breastfeeding support staff coverage that WIC clinics must have to meet the demand for services created by Lactation Advice Through Texting Can Help.

ABSTRACT

OBJECTIVE: The study aims were to (i) identify determinants of Nutrition Facts Panel (NFP) use and (ii) describe the association between NFP use and dietary intake among Latinos with type 2 diabetes. DESIGN: Baseline cross-sectional data from a clinical trial were used to assess the association between NFP use and dietary intake. Diet was measured using two methods: (i) a diet quality score (the Healthy Eating Index-2010) derived from a single 24 h recall and (ii) dietary pattern (exploratory factor analyses) from an FFQ. Multivariable logistic and non-parametric quantile regressions were conducted, as appropriate. Settings Hartford County, Connecticut, USA. SUBJECTS: Latino adults (n 203), ≥21 years of age, with diagnosed type 2 diabetes, glycosylated Hb≥7 %, and without medical conditions limiting physical activity. RESULTS: Participants' education level, diabetes-related knowledge and English speaking were positively associated with NFP use. At the higher percentiles of diet quality score, NFP use was significantly associated with higher diet quality. Similarly, NFP users were more likely to consume a 'healthy' dietary pattern (P=0·003) and less likely to consume a 'fried snack' pattern (P=0·048) compared with NFP non-users. CONCLUSIONS: The association between reported NFP use and diet quality was positive and significantly stronger among participants who reported consuming a healthier diet. While NFP use was associated with a healthier dietary pattern, not using NFP was associated with a less-healthy, fried snack pattern. Longitudinal studies are needed to understand whether improving NFP use could be an effective intervention to improve diet quality among Latinos with type 2 diabetes.

ABSTRACT

Background: Food insecurity (FI), diabetes prevalence, and poor diabetes outcomes all disproportionately affect Latinos in the United States. Heart rate variability (HRV) reflects autonomic tone, is associated with glycemic control, and predicts mortality in type 2 diabetes. It is unknown whether FI is related to HRV and, if so, whether glycemic control accounts for this association. Objective: This exploratory cross-sectional study examined FI and HRV among US Latinos with type 2 diabetes. Methods: Participants reported demographic characteristics, socioeconomic status, and FI, including the 6-item USDA food security module and a 1-item measure of diabetes-specific food security. Participants wore an ambulatory electrocardiogram monitor for 24 h. In the time domain, HRV was assessed with the SD of the R-R interval (SDNN). In the frequency domain, the power spectrum was integrated over 3 frequency bands-very low frequency (VLF), low frequency (LF), and high frequency (HF)-and then natural log transformed. Unadjusted ANOVA and ANCOVA adjusted for age, sex, glycated hemoglobin (HbA1c), and indicators of socioeconomic status compared food security groups on HRV. Results: Participants' mean ± SD age was 59.7 ± 10.9 y, and 73% were women. Of the 94 participants, 63 reported FI according to the USDA food security module and 46 reported FI according to the diabetes-specific measure. Mean ± SD HbA1c was 8.6% ± 1.7% and was marginally higher among those reporting diabetes-specific FI than those reporting diabetes-specific food security. Participants who reported diabetes-specific FI had lower SDNN, VLF, LF, and HF HRV with effect sizes in the small-to-medium range. Differences remained significant even after controlling for age, sex, socioeconomic hardship, and HbA1c. The 6-item USDA food security module was not associated with HRV. Conclusions: Diabetes-specific FI may be a unique risk factor for poor health outcomes among US Latinos. Efforts to address FI could benefit diabetes outcomes.

ABSTRACT

OBJECTIVE: To 1) describe the benefits, conditions, coverage, funding, goals, governance, and structure of well-established conditional cash transfer programs (CCTs) in Latin America and 2) identify their health and nutritional impacts among children under 5 years old. METHODS: A realist review was conducted. CCTs were included if they met the following inclusion criteria: 1) current national-level program; 2) coverage of at least 50% of the target population; 3) continuous operation at scale for 10+ years; 4) clear description of structure, funding sources, and governance; 5) both health/nutrition- and education-related conditions for participation; and 6) available impact evaluation studies with health, development, and/or nutrition indicators among children under 5 years old. Three CCTs (one each in Brazil, Colombia, and Mexico) met the criteria. RESULTS: There was consistent evidence that the three CCTs selected for review had positive impacts on child health and nutrition outcomes in their respective countries. In all three countries, the programs were scaled up and positive impacts were documented relatively quickly. All three programs had strong political support and clear and transparent governance structures, including accountability and social participation mechanisms, which might explain their success and sustainability. CONCLUSIONS: CCTs in Latin America have had a positive impact on child health and nutrition outcomes among the poorest families. A key challenge for the future is to reform these programs to help families move out of not only extreme poverty but all poverty in order to lead healthy and productive lives, as called for in the post-2105 Sustainable Development Goals.

ABSTRACT

AIMS: To test the efficacy of a community health worker (CHW) delivered stress management (SM) intervention on psychosocial, glycemic, and cortisol outcomes among U.S. Latinos with type 2 diabetes. METHODS: A randomized, controlled trial compared CHW-delivered diabetes education (DE; one group session) to DE plus CHW-delivered SM (DE+SM; 8 group sessions). Psychosocial variables and urinary cortisol were measured at baseline and posttreatment. HbA1c was measured at baseline, posttreatment, and 3-month follow-up. RESULTS: In intent to treat analysis, compared to DE (n=46), DE+SM (n=61) showed significantly improved symptoms of depression, anxiety, and self-reported health status. There were no significant group effects for HbA1c, diabetes distress, or urinary cortisol. However, there was a dose response effect for HbA1c and diabetes distress; increasing attendance at SM sessions was associated with greater improvements in HbA1c and diabetes distress. CONCLUSIONS: This is the first randomized, controlled trial demonstrating that CHWs can improve psychological symptoms and self-reported health among Latinos with type 2 diabetes. Efforts to increase intervention attendance may improve HbA1c and diabetes distress.
