RESUMEN

BACKGROUND AND AIMS: Heart failure (HF) patients are at risk of developing type 2 diabetes. This study examined the association between adherence to the Dietary Approaches to Stop Hypertension (DASH) diet and insulin resistance among U.S. adults with HF. METHODS AND RESULTS: Using data from National Health and Nutrition Examination Survey 1999-2016 cycles, we included 348 individuals aged 20+ years with HF and no history of diabetes. DASH diet adherence index quartile 1 indicated the lowest and quartile 4 indicated the highest adherence. The highest level of insulin resistance was defined by the upper tertile of the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). Associations between level of insulin resistance and DASH diet adherence and its linear trends were examined using logistic regressions. Trend analyses showed that participants in upper DASH diet adherence index quartiles were more likely older, female, non-Hispanic White, of normal weight, and had lower levels of fasting insulin than those in lower quartiles. Median values of HOMA-IR from lowest to highest DASH diet adherence index quartiles were 3.1 (interquartile range, 1.8-5.5), 2.9 (1.7-5.6), 2.1 (1.1-3.7), and 2.1 (1.3-3.5). Multivariable logistic analyses indicated that participants with the highest compared to the lowest DASH adherence showed 77.1% lower odds of having the highest level of insulin resistance (0.229, 95% confidence interval: 0.073-0.716; p = 0.017 for linear trend). CONCLUSION: Good adherence to the DASH diet was associated with lower insulin resistance among community-dwelling HF patients. Heart healthy dietary patterns likely protect HF patients from developing type 2 diabetes.

RESUMEN

Knowing the amounts of energy and nutrients in an individual's diet is important for maintaining health and preventing chronic diseases. As electronic and AI technologies advance rapidly, dietary assessment can now be performed using food images obtained from a smartphone or a wearable device. One of the challenges in this approach is to computationally measure the volume of food in a bowl from an image. This problem has not been studied systematically despite the bowl being the most utilized food container in many parts of the world, especially in Asia and Africa. In this paper, we present a new method to measure the size and shape of a bowl by adhering a paper ruler centrally across the bottom and sides of the bowl and then taking an image. When observed from the image, the distortions in the width of the paper ruler and the spacings between ruler markers completely encode the size and shape of the bowl. A computational algorithm is developed to reconstruct the three-dimensional bowl interior using the observed distortions. Our experiments using nine bowls, colored liquids, and amorphous foods demonstrate high accuracy of our method for food volume estimation involving round bowls as containers. A total of 228 images of amorphous foods were also used in a comparative experiment between our algorithm and an independent human estimator. The results showed that our algorithm overperformed the human estimator who utilized different types of reference information and two estimation methods, including direct volume estimation and indirect estimation through the fullness of the bowl.

RESUMEN

Breastfeeding benefits both infant and mother, including reducing the risk of Sudden Infant Death Syndrome (SIDS). To further reduce risk of SIDS, the American Academy of Pediatrics recommends infants sleep on their backs on a separate sleep surface. Our objective was to describe trends and factors associated with breastfeeding and infant sleep practices in Georgia. Pregnancy Risk Assessment Monitoring System 2004-2013 data were obtained from the Georgia Department of Public Health. Chi square tests for trends were utilized to determine whether there were significant linear trends in breastfeeding and infant sleep overtime and by survey phase. After exclusions, 4643 cases remained for analysis. From 2004 to 2013, there was a slight (insignificant) decrease in breastfeeding initiation, with the highest proportion in 2010 (79.9%) and the lowest in 2013 (66.9%). Rates of exclusive breastfeeding increased significantly from 2004 (31.3%) to 2013 (81.7%). During that time, the proportion of infants being placed back to sleep slightly decreased (though not significantly), from 59.7 to 48.9%. The proportion of mothers who reported never bed-sharing increased significantly from 26.7 to 45.1% over this period. The decreasing breastfeeding initiation rates in Georgia diverge from national upward trends, however, exclusive breastfeeding rates by survey phase were slightly higher than national trends. Our results suggest the need for targeted education and support for breastfeeding and safe sleep practices. State-level trends data on breastfeeding and infant sleep practices provide valuable information for state-level public health professionals and policy makers, health care providers, and breastfeeding and safe sleep advocates.

RESUMEN

Camera-based passive dietary intake monitoring is able to continuously capture the eating episodes of a subject, recording rich visual information, such as the type and volume of food being consumed, as well as the eating behaviors of the subject. However, there currently is no method that is able to incorporate these visual clues and provide a comprehensive context of dietary intake from passive recording (e.g., is the subject sharing food with others, what food the subject is eating, and how much food is left in the bowl). On the other hand, privacy is a major concern while egocentric wearable cameras are used for capturing. In this article, we propose a privacy-preserved secure solution (i.e., egocentric image captioning) for dietary assessment with passive monitoring, which unifies food recognition, volume estimation, and scene understanding. By converting images into rich text descriptions, nutritionists can assess individual dietary intake based on the captions instead of the original images, reducing the risk of privacy leakage from images. To this end, an egocentric dietary image captioning dataset has been built, which consists of in-the-wild images captured by head-worn and chest-worn cameras in field studies in Ghana. A novel transformer-based architecture is designed to caption egocentric dietary images. Comprehensive experiments have been conducted to evaluate the effectiveness and to justify the design of the proposed architecture for egocentric dietary image captioning. To the best of our knowledge, this is the first work that applies image captioning for dietary intake assessment in real-life settings.

RESUMEN

Background: Shared plate eating (SPE), defined as two or more individuals eating directly from the same plate or bowl, is a common household food consumption practice in many Low- and Middle-Income Countries (LMICs). Examination of household engagement in SPE remains largely unexplored, highlighting a gap in research when interpreting dietary information obtained from these settings. The dearth of research into SPE can be attributed to the inherent limitations of traditional dietary assessment methods which constrain their usability in settings where SPE is common. Objective: In this expository narrative, we describe what SPE is when it is practiced in an LMIC such as Ghana; and also compare the frequency of SPE versus individual plate eating (IPE) by different household members in rural and urban households using a wearable camera (Automatic Ingestion Monitor version 2: AIM-2). Methods: Purposive convenience sampling was employed to recruit and enroll 30 households each from an urban and a rural community (n = 60 households) in Ghana. The AIM-2 was worn on eyeglass frames for 3 days by selected household members. The AIM-2, when worn, automatically collects images to capture food consumption in participants' environments, thus enabling passive capture of household SPE dynamics. Results: A higher percentage of SPE occasions was observed for rural (96.7%) compared to urban (36.7%) households (p < 0.001). Common SPE dynamics included only adults sharing, adults and children sharing, only children sharing, and non-household member participation in SPE. Conclusion: The wearable camera captured eating dynamics within households that would have likely been missed or altered by traditional dietary assessment methods. Obtaining reliable and accurate data is crucial for assessing dietary intake in settings where SPE is a norm.

RESUMEN

OBJECTIVE: Examine how experiencing the coronavirus disease 2019 (COVID-19) pandemic influenced adolescent independent eating occasions (iEOs) and iEO-related parenting practices from the perspective of parents and adolescents METHODS: Cross-sectional remote interviews were conducted for this basic qualitative research study. Participants were a purposive sample of multiracial/ethnic adolescents aged 11-14 years and their parents from households with low income (n = 12 dyads) representing 9 US states. The main outcome measures were iEOs and iEO-related parenting practices. Data were analyzed using directed content analysis. RESULTS: About half of the parents indicated that their adolescents had more iEOs during the COVID-19 pandemic and that there were changes in the types of foods consumed during iEOs. In contrast, most adolescents indicated their iEOs had not changed remarkably in frequency or foods consumed since the onset of the pandemic. Most parents reported no change in how they taught their adolescents about healthy food, the rules for foods/beverages permitted during iEOs, or how they monitored what their adolescents ate during iEOs; adolescent reports were in general agreement. Most parents indicated that family members were home together more often during the pandemic, which increased cooking frequency. CONCLUSIONS AND IMPLICATIONS: The effect of the COVID-19 pandemic on adolescents' iEOs varied, and the parenting practices used to influence iEOs remained stable during the pandemic. Families experienced having more time together and cooking at home more often.

RESUMEN

BACKGROUND: Accurate estimation of dietary intake is challenging. However, whilst some progress has been made in high-income countries, low- and middle-income countries (LMICs) remain behind, contributing to critical nutritional data gaps. This study aimed to validate an objective, passive image-based dietary intake assessment method against weighed food records in London, UK, for onward deployment to LMICs. METHODS: Wearable camera devices were used to capture food intake on eating occasions in 18 adults and 17 children of Ghanaian and Kenyan origin living in London. Participants were provided pre-weighed meals of Ghanaian and Kenyan cuisine and camera devices to automatically capture images of the eating occasions. Food images were assessed for portion size, energy, nutrient intake, and the relative validity of the method compared to the weighed food records. RESULTS: The Pearson and Intraclass correlation coefficients of estimates of intakes of food, energy, and 19 nutrients ranged from 0.60 to 0.95 and 0.67 to 0.90, respectively. Bland-Altman analysis showed good agreement between the image-based method and the weighed food record. Under-estimation of dietary intake by the image-based method ranged from 4 to 23%. CONCLUSIONS: Passive food image capture and analysis provides an objective assessment of dietary intake comparable to weighed food records.

RESUMEN

BACKGROUND: Frequency of independent eating occasions (iEOs) has been linked to intake of unhealthy foods and overweight or obesity among adolescents. Parenting practices involving modeling healthy food intake and making healthy foods available have been associated with healthy food intake among adolescents; however, little is known about these associations during iEOs. OBJECTIVE: To determine whether parenting practices involving structure (monitoring, availability, modeling, and expectations), lack of structure (indulgence), and autonomy support reported by adolescents or parents were associated with adolescent iEO intake of junk foods, sugar-sweetened beverages (SSBs), sugary foods, and fruit and vegetables. DESIGN: Cross-sectional study measuring parenting practices and adolescent iEO food choices via an online survey and adapted food frequency questionnaire. PARTICIPANTS/SETTING: Parent/adolescent dyads (n = 622) completed surveys (November-December 2021) using a national Qualtrics panel database. Adolescents were 11 to 14 years of age and had iEOs at least weekly. MAIN OUTCOME MEASURES: Primary measures included parent- and adolescent-reported frequency of food parenting practices and adolescent-reported iEO intake of junk foods, sugary foods, SSBs, and fruits and vegetables. STATISTICAL ANALYSES PERFORMED: Multivariable linear regression models were used to examine associations between parenting practices and iEO intake of foods/beverages, adjusting for adolescent's age, sex, race and ethnicity, iEO frequency, parent's education and marital status, and household food security status. Bonferroni multiple comparison corrections were conducted. RESULTS: More than half of parents were female (66%) and 35 to 64 years of age (58%). Adolescents/parents identified as White/Caucasian (44%/42%), Black/African American (28%/27%), Asian (21%/23%), and Hispanic ethnicity (42%/42%). Positive associations were observed among adolescent-reported and parent-reported autonomy support, monitoring, indulgence and expectations parenting practices, and adolescent-reported daily iEO intake frequencies of junk foods, sugary foods, and fruits and vegetables (P < 0.001). CONCLUSIONS: Structural and autonomy support parenting practices were positively associated with both healthy and unhealthy iEO food intake by adolescents. Interventions to improve adolescent iEO intake could promote positive practices associated with healthy food consumption.

RESUMEN

OBJECTIVE: Western diet is associated with chronic disease risk, and degree of dietary acculturation can impact susceptibility. This study sought to understand the factors associated with changes in food consumption habits among international students at a large public university in the southern US. PARTICIPANTS: A convenience sample of 173 international students representing 41 countries at The University of Georgia participated in the survey. METHODS: This cross-sectional online survey assessed dietary habits, perception of healthy eating, and level of acculturation using previously validated measures. RESULTS: Highest number of participants were from China (19.2%), 89.0% were graduate students with an average age of 27.5 ± 4.83 years. The majority (62.0%) of participants were dietary acculturated with affordability and accessibility determining types of food consumption, as fewer whole foods and more processed foods were consumed in the U.S. CONCLUSIONS: Findings suggest dietary acculturation may be driven by economic factors, making the transition to Westernized food items a convenient and cost-effective choice among international students.

RESUMEN

AIMS: This study estimated national prevalence and trends of diagnosed and undiagnosed type 2 diabetes mellitus (T2DM) and prediabetes among heart failure (HF) patients in the U.S. METHODS: This cross-sectional study included 527 participants aged 20+ years with a diagnosis of HF, using data from the National Health and Nutrition Examination Survey 2005-2016. We assessed prevalence estimates of diagnosed and undiagnosed T2DM and prediabetes stratified by age-standardized sociodemographic and health characteristics. Trends of T2DM and prediabetes prevalence were examined using logistic regressions. RESULTS: Prevalence rates of diagnosed and undiagnosed T2DM among HF patients were 34.7% (95% confidence interval (CI), 29.2-40.3%) and 12.8% (95% CI, 9.2-16.9%), respectively. Prediabetes affected 39.1% (95% CI, 33.6-44.9%) of HF patients. Prevalence estimates of diagnosed T2DM were significantly different between non-Hispanic White (20.1% [95% CI, 13.5-27.6%]) and Hispanic participants (52.1% [95% CI, 35.9-68.0%]) (P < 0.001). The prevalence of T2DM and prediabetes did not significantly change between 2005 and 2016. CONCLUSIONS: Prevalence rates of T2DM and prediabetes among community-dwelling HF patients in the U.S. remained high between 2005 and 2016. Prevention of and targeted intervention for T2DM among at-risk HF patients is needed, particularly among those of Hispanic origin.

RESUMEN

Malnutrition, including both undernutrition and obesity, is a significant problem in low- and middle-income countries (LMICs). In order to study malnutrition and develop effective intervention strategies, it is crucial to evaluate nutritional status in LMICs at the individual, household, and community levels. In a multinational research project supported by the Bill & Melinda Gates Foundation, we have been using a wearable technology to conduct objective dietary assessment in sub-Saharan Africa. Our assessment includes multiple diet-related activities in urban and rural families, including food sources (e.g., shopping, harvesting, and gathering), preservation/storage, preparation, cooking, and consumption (e.g., portion size and nutrition analysis). Our wearable device ("eButton" worn on the chest) acquires real-life images automatically during wake hours at preset time intervals. The recorded images, in amounts of tens of thousands per day, are post-processed to obtain the information of interest. Although we expect future Artificial Intelligence (AI) technology to extract the information automatically, at present we utilize AI to separate the acquired images into two binary classes: images with (Class 1) and without (Class 0) edible items. As a result, researchers need only to study Class-1 images, reducing their workload significantly. In this paper, we present a composite machine learning method to perform this classification, meeting the specific challenges of high complexity and diversity in the real-world LMIC data. Our method consists of a deep neural network (DNN) and a shallow learning network (SLN) connected by a novel probabilistic network interface layer. After presenting the details of our method, an image dataset acquired from Ghana is utilized to train and evaluate the machine learning system. Our comparative experiment indicates that the new composite method performs better than the conventional deep learning method assessed by integrated measures of sensitivity, specificity, and burden index, as indicated by the Receiver Operating Characteristic (ROC) curve.

RESUMEN

Malnutrition is a major concern in low- and middle-income countries (LMIC), but the full extent of nutritional deficiencies remains unknown largely due to lack of accurate assessment methods. This study seeks to develop and validate an objective, passive method of estimating food and nutrient intake in households in Ghana and Uganda. Household members (including under-5s and adolescents) are assigned a wearable camera device to capture images of their food intake during waking hours. Using custom software, images captured are then used to estimate an individual's food and nutrient (i.e., protein, fat, carbohydrate, energy, and micronutrients) intake. Passive food image capture and assessment provides an objective measure of food and nutrient intake in real time, minimizing some of the limitations associated with self-reported dietary intake methods. Its use in LMIC could potentially increase the understanding of a population's nutritional status, and the contribution of household food intake to the malnutrition burden. This project is registered at clinicaltrials.gov (NCT03723460).

RESUMEN

OBJECTIVE: To measure the energy content of frequently ordered meals from full service and fast food restaurants in five countries and compare values with US data. DESIGN: Cross sectional survey. SETTING: 223 meals from 111 randomly selected full service and fast food restaurants serving popular cuisines in Brazil, China, Finland, Ghana, and India were the primary sampling unit; 10 meals from five worksite canteens were also studied in Finland. The observational unit was frequently ordered meals in selected restaurants. MAIN OUTCOME MEASURE: Meal energy content, measured by bomb calorimetry. RESULTS: Compared with the US, weighted mean energy of restaurant meals was lower only in China (719 (95% confidence interval 646 to 799) kcal versus 1088 (1002 to 1181) kcal; P<0.001). In analysis of variance models, fast food contained 33% less energy than full service meals (P<0.001). In Finland, worksite canteens provided 25% less energy than full service and fast food restaurants (mean 880 (SD 156) versus 1166 (298); P=0.009). Country, restaurant type, number of meal components, and meal weight predicted meal energy in a factorial analysis of variance (R2=0.62, P<0.001). Ninety four per cent of full service meals and 72% of fast food meals contained at least 600 kcal. Modeling indicated that, except in China, consuming current servings of a full service and a fast food meal daily would supply between 70% and 120% of the daily energy requirements for a sedentary woman, without additional meals, drinks, snacks, appetizers, or desserts. CONCLUSION: Very high dietary energy content of both full service and fast food restaurant meals is a widespread phenomenon that is probably supporting global obesity and provides a valid intervention target.

RESUMEN

The authors analyzed data from a trial assessing the efficacy of breastfeeding peer counseling (PC) for increasing exclusive breastfeeding (EBF) to (1) examine whether different ethnic groups responded differently to the intervention and (2) document the determinants of EBF. At 2 months postpartum, the prevalence of EBF in the intervention group was 11.4% among Puerto Ricans compared to 44.4% among non-Puerto Ricans (P = .008). Multivariate logistic regression analyses showed that women who had the intention prenatally to engage in EBF were more likely to do so and those whose mothers lived in the United States were less likely to engage in EBF at hospital discharge. At 2 months postpartum, mothers who were breastfed as children were more likely to engage in EBF, whereas non-Puerto Ricans had a significantly greater response to the intervention than Puerto Ricans (odds ratio, 6.40; 95% confidence interval, 1.45-28.33). There is a need for further studies to determine why different ethnic groups respond differently to EBF promotion interventions.

RESUMEN

BACKGROUND: According to the Centers for Disease Control and Prevention, 39.1% of African American infants are breastfed at 6 months. However, few studies have explored the breastfeeding experiences of African American women who successfully breastfeed to 6 months or longer durations. Research aim: The goal of this qualitative study was to explore the long-term breastfeeding experiences of low-income African American women using the positive deviance approach. METHODS: African American women with breastfeeding experience were recruited through Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) breastfeeding peer counselors. Eligibility criteria included being age 18 or older, currently participating in WIC, and having breastfed one child for at least 6 months in the past 2 years. Semistructured, in-depth interviews were conducted with 11 participants. Interviews were audio-recorded and professionally transcribed. Transcripts were then analyzed for emerging themes using thematic analysis in NVivo software. RESULTS: Participants had on average three children each, with an average length of breastfeeding of 10.5 months per child. Four main themes developed: (a) deciding to breastfeed, (b) initiating breastfeeding, (c) breastfeeding long-term, and (d) expanding breastfeeding support. Participants offered culturally tailored suggestions to improve breastfeeding support for other African American women: prenatal discussions of breastfeeding with health care providers, African American lactation support personnel and breastfeeding support groups, and African American breastfeeding promotion in print and digital media. CONCLUSION: Women who participated in this study breastfed for longer durations than the national average for African Americans. Findings can inform practice and research efforts to improve breastfeeding rates in this population using lessons learned from successful women.

RESUMEN

OBJECTIVE: To assess the efficacy of peer counseling to promote exclusive breastfeeding (EBF) among low-income inner-city women in Hartford, Conn. DESIGN: Participants recruited prenatally were randomly assigned to either receive support for EBF from a peer counselor plus conventional breastfeeding support (peer counseling group [PC]) or only conventional breastfeeding support (control group [CG]) and followed through 3 months post partum. SETTING: Low-income predominantly Latina community. PARTICIPANTS: Expectant mothers, less than 32 weeks gestation and considering breastfeeding (N = 162). Intervention Exclusive breastfeeding peer counseling support offering 3 prenatal home visits, daily perinatal visits, 9 postpartum home visits, and telephone counseling as needed. MAIN OUTCOME MEASURES: Exclusive breastfeeding rates at hospital discharge, 1, 2, and 3 months post partum (n = 135). RESULTS: At hospital discharge, 24% in the CG compared with 9% in the PC had not initiated breastfeeding, with 56% and 41%, respectively, nonexclusively breastfeeding. At 3 months, 97% in the CG and 73% in the PC had not exclusively breastfed (relative risk [RR] = 1.33; 95% CI, 1.14-1.56) during the previous 24 hours. The likelihood of nonexclusive breastfeeding throughout the first 3 months was significantly higher for the CG than the PC (99% vs 79%; RR = 1.24; 95% CI, 1.09-1.41). Mothers in the CG were less likely than their PC counterparts to remain amenorrheic at 3 months (33% vs 52%; RR = 0.64; 95% CI, 0.43-0.95). The likelihood of having 1 or more diarrheal episode in infants was cut in half in the PC (18% vs 38%; RR = 2.15; 95% CI, 1.16-3.97). CONCLUSION: Well-structured, intensive breastfeeding support provided by hospital and community-based peer counselors is effective in improving exclusive breastfeeding rates among low-income, inner-city women in the United States.

RESUMEN

BACKGROUND: African American women have the lowest breastfeeding rates among all racial/ethnic groups in the United States. Peer counseling is an effective intervention in improving breastfeeding in this population. However, little is known on peer counselors' perceptions of breastfeeding in African American women. OBJECTIVE: As part of a larger qualitative study, the goal of this study was to understand the contextual factors influencing breastfeeding decisions of low-income African American women from the perspective of breastfeeding peer counselors (PCs). METHODS: Three focus groups were conducted with 23 PCs from the Women, Infants, and Children program in a southeastern state. All focus group discussions were audio-recorded, professionally transcribed, and analyzed using thematic analysis. Bronfenbrenner's socioecological model was used to group categories into themes. RESULTS: Of the sample, 47.8% were African American, 78.2% were married, and 56.5% had some college education. Five main themes emerged to describe factors at multiple levels influencing breastfeeding in PCs' low-income African American clients: individual, microsystem, exosystem, macrosystem, and chronosystem. Novel findings included (1) having breast pumps may give African American women a "sense of security," (2) cultural pressures to be a "strong black woman" can impede breastfeeding support, and (3) breastfeeding "generational gaps" have resulted from American "slavery" and when formula was "a sign of wealth." CONCLUSION: As PCs described, low-income African American women's breastfeeding decisions are affected by numerous contextual factors. Findings from this study suggest a need to broaden the public health approach to breastfeeding promotion in this population by moving beyond individual characteristics to examining historical and sociocultural factors underlying breastfeeding practices in African American women.

RESUMEN

To examine reasons for not breastfeeding, and to identify factors associated with ever breastfeeding among Puerto Rican women, a retrospective study was done using a convenience sample of 161 low-income Latino women with children younger than 6 years. Women were recruited from the Hispanic Health Council (43.5%), the Supplemental Nutrition Program for Women, Infants, and Children (29.8%), and other places (26.7%). Participants were interviewed using a pretested questionnaire specific to the target community. Most (73%) of the respondents chose to be interviewed in Spanish. Chi-square analyses were used to examine the bivariate association between ever breastfeeding and the independent variables. Multivariate logistic regression was conducted to estimate the independent association between acculturation, social capital, and breastfeeding. Women with more social capital were more likely (odds ratio = 2.25, 95% confidence interval, 1.02-4.95) to have breastfed the index child, suggesting that social capital is an important predictor of breastfeeding initiation in this community.

RESUMEN

BACKGROUND: The prevalence of low birth weight (LBW) is a major public health issue in India (30.0%) and is the highest among South-Asian countries. Maternal autonomy or the mother's status in the household indicates her decision-making power with respect to movement, finance, healthcare use, and other household activities. Evidence suggests that autonomy of the mother is significantly associated with the child's nutritional status. Although previous studies in India reported the determinants of LBW, literature on the association between mother's autonomy and birth weight are lacking. This study, therefore, aims to examine the influence of maternal autonomy on birth weight of the newborn. METHODS: The study, a secondary data analysis, examined data from the 2005-2006 National Health and Family Survey (NFHS 3) of India. A maternal autonomy score was created through proximal component factor analysis and categorized as high, medium, and low autonomy levels. The main outcome variable included birth weight of the index child obtained from health cards and mother's recall. Descriptive and logistic regression analyses were performed. RESULTS: Results from the study indicate that 20.0% of the index children included in the analysis were born at LBW. Low maternal autonomy was an independent predictor of LBW (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.07-1.53, p=0.007) after adjusting for other factors, and medium autonomy level was not significant. CONCLUSIONS: These findings clearly indicate the importance of empowering women in India to combat the high incidence of LBW.

RESUMEN

BACKGROUND: Studies using community-based breastfeeding counselors (CBBCs) have repeatedly shown positive impact on breastfeeding initiation, exclusivity and duration, particularly among low-income mothers. To date, there has not been a comprehensive study to determine the impact of CBBC attributes such as educational background and training, on the type of care that CBBCs provide. METHODS: This was a cross-sectional study of a convenience sample of CBBCs to ascertain the influence of counselor education and type of training on type of support and proficiency of CBBCs in communities across the United States. Invitations to participate in this online survey of CBBCs were e-mailed to program coordinators of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), La Leche League, and other community-based health organizations, who in turn invited and encouraged their CBBCs to participate. Descriptive analysis was used to describe participants (N = 847), while bivariate analysis using χ2 test was used to examine the differences between CBBC education, training received and breastfeeding support skills used. Multivariate logistic regression was used to assess the independent determinants of specific breastfeeding support skills. RESULTS: The major findings from the research indicate that overall, educational attainment of CBBCs is not a significant predictor for the curriculum used in their training and type of support skills used during counseling sessions, but initial training duration was positively associated with the use of many breastfeeding support skills. Another major influence of counselor support to clients is the type of continuing education they receive after their initial training, with higher likelihood of use of desirable support skills associated with counselors continuing their breastfeeding education at conferences or trainings away from their job sites. CONCLUSIONS: Our results show that different programs use different training curricula to train their CBBCs varying in duration and content. Counselor education is not a significant predictor of the type of training they receive. Continuing breastfeeding education is a significant determinant of type of counseling techniques used with clients. Further research is therefore needed to critically examine the content of the various training curricula of CBBC programs. This may show a need for a standardized training curriculum for all CBBC programs worldwide to make CBBCs more proficient and efficient, ensuring successful and optimum breastfeeding experiences for mothers and their newborns.
