Etiologies of Mild and Moderate Diarrheal Illness among Children in Consuelo, Dominican Republic.

Since the rotavirus vaccine was included in the Dominican Republic's national immunization schedule in 2012, the microbiologic etiologies of acute gastroenteritis have not been described. This study aimed to determine the contribution of rotavirus as an etiology of acute gastroenteritis over a 12-month period in children under 5 years of age in both an inpatient and an outpatient setting in Consuelo, Dominican Republic. All children who were seen at Niños Primeros en Salud clinic or admitted to Hospital Municipal Dr. Angel Ponce Pinedo for acute gastroenteritis during January 2021-April 2022 were enrolled in the study. Stools were evaluated for rotavirus, enteric parasites, and pathogenic bacteria. Pathogen detection was compared between outpatients and inpatients and on the basis of child's vaccination status. From 181 children enrolled, 170 stool samples were collected, 28 (16.5%) from inpatients and 142 (83.5%) from outpatients. Rotavirus was the most commonly detected pathogen and was proportionately more common among hospitalized children, with nine (32.1%) cases among hospitalized children and 16 (11.3%) among outpatient children. (Pearson χ2 = 8.1, P = 0.004). Among patients with a positive rotavirus result, vaccination rate was lower among moderate (hospitalized) (three of six; 50%) compared with mild (outpatient) diarrhea patients (12 of 15; 80%). Giardia lamblia (10%) was the next most prevalent pathogen detected in both inpatients and outpatients using standard laboratory measures. Despite the availability of rotavirus vaccination, rotavirus remains a common cause of gastrointestinal illness among children under 5 years of age in our cohort. Incomplete vaccination status was associated with hospitalization for gastrointestinal illness.

Factors Associated With Initiating Breastfeeding and Continuing it for At Least 4 Months in Consuelo, a Rural Town in the Dominican Republic.

Objective. We assessed the proportion of and factors associated with mothers initiating and continuing breastfeeding (BF) for ≥4 months in a rural town of the Dominican Republic. Methods. A survey was administered to 190 mothers of children cared for at a free clinic in Consuelo. Modified bivariate and multivariable Poisson regressions were utilized in data analysis. Results. BF was initiated in 89.5% of cases and continued ≥4 months in 81.7% of cases. Maternal education beyond secondary school [adjusted RR = 1.13, 95% CI: (1.04-1.24), 0.010], and visiting both public and private antenatal clinics [adjusted RR = 1.25; 95% CI: (1.10-1.37), 0.010] were associated with BF initiation. Public and private antenatal clinic attendance [adjusted RR = 1.01, 95% CI: (0.45-2.23), 0.020], Cesarean section [adjusted RR = 0.81, 95% CI: (0.68-0.98), 0.026], number of biological children [adjusted RR = 0.95, 95% CI: (0.90-1.00), 0.032] and maternal employment [adjusted RR = 0.89, 95% CI: (0.79-0.99), 0.048] were associated with BF continuation. Conclusions. These results provide valuable insights for targeting specific populations in future breastfeeding education interventions.

Evaluation of iron intake in preschool children in a setting with high anemia burden.

BACKGROUND: Iron deficiency anemia affects millions of children worldwide. Iron intake assessments can inform targeted interventions. METHODS: This cross-sectional study describes diet and hemoglobin levels of children 1-5 y of age in a resource-limited setting in the Dominican Republic. The study team performed meal observations and measurements, dietary questionnaires, and point-of-care hemoglobin testing. RESULTS: Iron intake and bioavailability were low, with liberal estimates indicating that not more than 40% of subjects consumed the recommended daily allowance for iron. Forty of 80 children had anemia, with 23% demonstrating moderate or severe anemia. CONCLUSIONS: Poor observed iron intake likely contributes to the high prevalence of anemia in this population.

Effectiveness of Deworming with Single-Dose Albendazole for Preschool-Aged Children in the Dominican Republic.

Background. The World Health Organization recommends biannual deworming with single-dose albendazole for all children over 1 year in regions where soil-transmitted helminths (STH) are endemic. There are limited data from the Dominican Republic (DR) on the effectiveness of deworming programs. Methods. Between January and June 2019, we enrolled 63 preschool-aged children at a community clinic in the DR. Participants received albendazole at enrollment. Stool samples were collected and examined for parasites at enrollment, 2 to 4 and 12 to 16 weeks post-albendazole. Caregivers were surveyed on home hygiene practices and children's symptoms. Findings. At enrollment, 1 or more parasites were noted in 89% of samples. Ascaris lumbricoides (68%) was the most common species, followed by Entamoeba histolytica (35%) and Giardia intestinalis (8%). Two-to-four weeks post-albendazole, fewer than half of those with A. lumbricoides infections at baseline had cleared the infection. STH symptoms significantly improved between enrollment and 2 to 4 weeks. By 12 to 16 weeks after treatment, A. lumbricoides infections were as high as baseline. Interpretation. Although limited by size and available technology, our study contributes data on STH in the DR. Single-dose deworming with albendazole did not reduce Ascaris lumbricoides infections in our sample. As STH are the most common neglected tropical diseases and negatively impact children's health globally, further studies on both effective deworming programs and interventions to prevent STH are needed.

Caregiver Strengths, Attitudes, and Concerns About Reading and Child Development in the Dominican Republic.

Background. Parents' beliefs about and engagement in reading aloud to young children and other positive parenting practices have been associated with early childhood development (ECD) and later achievement. Aim. This exploratory study sought to assess parental attitudes and self-reported practices regarding ECD in a rural, low-income community in the Dominican Republic with many risk factors for ECD delays, including high rates of poverty, iron-deficiency anemia, and malnutrition. Methods. We used the Parent Reading Belief Inventory and open-ended questions to evaluate parental beliefs regarding reading, self-efficacy in promoting child development, current positive parenting practices, and parents' concerns about the development of their 0- to 5-year-old children in Consuelo, Dominican Republic. We explored associations between demographic factors and strength of positive parenting beliefs and practices. Results. Overall participants had positive attitudes toward reading and their own importance in promoting their children's development. Participants with at least some high school education had significantly higher Parent Reading Belief Inventory scores (P = .03) than those with less formal education. Participants reported frequently singing, talking, and playing with their children, but less frequently reading with them. Few participants had access to reading materials for young children. Parental interest in programs to support ECD was high. Parents raised concerns about their children's behavior, personal and educational attainment, and early literacy. Conclusion. Children whose parents have less formal education may benefit most from interventions to promote beliefs and practices likely to improve ECD. In this community, there is high interest in learning more about ECD.

Perceptions and Attitudes Toward Mobile Health in Development of an Exclusive Breastfeeding Tool: Focus Group Study With Caregivers and Health Promoters in the Dominican Republic.

BACKGROUND: Despite growing interest in the use of technology to improve health outcomes in low- and middle-income countries (LMICs), local attitudes toward mobile health (mHealth) use in these settings are minimally understood. This is especially true in the Dominican Republic, where mHealth interventions are starting to emerge. This information is critical for developing effective mHealth interventions to address public health issues, such as low exclusive breastfeeding (EBF) rates, which can lead to poor outcomes. With an EBF rate of 5% in the first 6 months of life, the Dominican Republic has one of the lowest EBF rates worldwide. OBJECTIVE: This study aims to describe the current use of information and communication technology (ICT) and to analyze the attitudes and perceptions related to using mHealth interventions among caregivers of children aged ≤5 years and health promoters in the Dominican Republic. Findings can inform mHealth strategies aimed at improving EBF in this, and other, LMICs. METHODS: Participants were recruited from 3 outpatient sites: the Niños Primeros en Salud program at Centro de Salud Divina Providencia in Consuelo (rural setting) and Clínica de Familia La Romana and its program Módulo de Adolescentes Materno Infantil in La Romana (urban setting). Focus groups were conducted with caregivers and community health promoters to identify the use, attitudes, perceptions, and acceptability of mHealth as well as barriers to EBF. Discussions were conducted in Spanish, guided by semistructured interview guides. All sessions were audio-recorded and later transcribed. Thematic content analysis was conducted in Spanish by two bilingual researchers and was structured around a hybrid behavioral theory framework to identify salient themes. RESULTS: All participants (N=35) reported having a mobile phone, and 29 (83%) participants had a smartphone. Sources for obtaining health information included the internet, physicians and clinic, family and friends, health promoters, and television. Barriers to mHealth use included the cost of internet service, privacy concerns, and perceived credibility of information sources. Participants indicated the desire for, and willingness to use, an mHealth intervention to support breastfeeding. The desired features of a possible mHealth intervention included offering diverse methods of information delivery such as images and video content, text messages, and person-to-person interaction as well as notifications for appointments, vaccines, and feeding schedules. Other important considerations were internet-free access and content that included maternal and child health self-management topics beyond breastfeeding. CONCLUSIONS: There is a high level of acceptance of ICT tools for breastfeeding promotion among caregivers in urban and rural areas of the Dominican Republic. As mHealth tools can contribute to increased breastfeeding self-efficacy, identifying desirable features of such a tool is necessary to create an effective intervention. Participants wanted to receive trusted and reliable information through various formats and were interested in information beyond breastfeeding.

The impact of access to immunization information on vaccine acceptance in three countries.

INTRODUCTION: Vaccine acceptance is a critical component of sustainable immunization programs, yet rates of vaccine hesitancy are rising. Increased access to misinformation through media and anti-vaccine advocacy is an important contributor to hesitancy in the United States and other high-income nations with robust immunization programs. Little is known about the content and effect of information sources on attitudes toward vaccination in settings with rapidly changing or unstable immunization programs. OBJECTIVE: The objective of this study was to explore knowledge and attitudes regarding vaccines and vaccine-preventable diseases among caregivers and immunization providers in Botswana, the Dominican Republic, and Greece and examine how access to information impacts reported vaccine acceptance. METHODS: We conducted 37 focus groups and 14 semi-structured interviews with 96 providers and 153 caregivers in Botswana, the Dominican Republic, and Greece. Focus groups were conducted in Setswana, English, Spanish, or Greek; digitally recorded; and transcribed. Transcripts were translated into English, coded in qualitative data analysis software (NVivo 10, QSR International, Melbourne, Australia), and analyzed for common themes. RESULTS: Dominant themes in all three countries included identification of health care providers or medical literature as the primary source of vaccine information, yet participants reported insufficient communication about vaccines was available. Comments about level of trust in the health care system and government contrasted between sites, with the highest level of trust reported in Botswana but lower levels of trust in Greece. CONCLUSIONS: In Botswana, the Dominican Republic, and Greece, participants expressed reliance on health care providers for information and demonstrated a need for more communication about vaccines. Trust in the government and health care system influenced vaccine acceptance differently in each country, demonstrating the need for country-specific data that focus on vaccine acceptance to fully understand which drivers can be leveraged to improve implementation of immunization programs.
