Objectives The importance of mother-child interaction in early infancy on child development has been well documented. The purpose of this study was to assess the feasibility of using the Still Face Paradigm to measure mother interactive style, infant affect and emotional regulation in a rural Ecuador setting. Methods Infant’s emotional regulation and the quality of mother’s interaction were measured with the Still Face Paradigm at 4 months of age (±15 days). Twenty-four infants and their mothers were assessed in their home. Mother interactive style was coded for attention seeking and contingent responding. Emotional regulation was described by change in infant affect between Still Face episodes. Results A significant difference was found for infant affect between the five Still Face episodes (F1,118 = 9.185, p = 0.003). A significant negative correlation was found for infant affect between episode 3 and 2 with attention seeking mother interactive style during episode 3 (rho = −0.44, p = 0.03), indicating that mothers using more contingent-responding interactions had infants with more positive affect. Conversely, a significant positive association was found for infant affect between episode 3 and 2 and contingent responding mother interactive style during episode 3 (rho = 0.46, p = 0.02), indicating that mothers who used more attention seeking play had infants who showed less positive affect. Conclusion for Practice Study results demonstrate feasibility in using the Still Face Paradigm in working populations residing in a rural region in Ecuadorian highlands and may be feasible in other similar populations in Latin America, and as a successful approach to measuring maternal-child interactions within a field-based epidemiological study design.

Introduction Several studies have measured health outcomes in the United States, but none have provided a comprehensive assessment of patterns of health by state. Objective To use the results of the Global Burden of Disease Study (GBD) to report trends in the burden of diseases, injuries, and risk factors at the state level from 1990 to 2016. Design and Setting A systematic analysis of published studies and available data sources estimates the burden of disease by age, sex, geography, and year. Main Outcomes and Measures Prevalence, incidence, mortality, life expectancy, healthy life expectancy (HALE), years of life lost (YLLs) due to premature mortality, years lived with disability (YLDs), and disability-adjusted life-years (DALYs) for 333 causes and 84 risk factors with 95% uncertainty intervals (UIs) were computed. Results Between 1990 and 2016, overall death rates in the United States declined from 745.2 (95%UI, 740.6 to 749.8) per 100 000 persons to 578.0 (95%UI, 569.4 to 587.1) per 100 000 persons. The probability of death among adults aged 20 to 55 years declined in 31 states and Washington, DC from 1990 to 2016. In 2016, Hawaii had the highest life expectancy at birth (81.3 years) and Mississippi had the lowest (74.7 years), a 6.6-year difference. Minnesota had the highest HALE at birth (70.3 years), andWest Virginia had the lowest (63.8 years), a 6.5-year difference. The leading causes of DALYs in the United States for 1990 and 2016 were ischemic heart disease and lung cancer, while the third leading cause in 1990 was low back pain, and the third leading cause in 2016 was chronic obstructive pulmonary disease. Opioid use disorders moved from the 11th leading cause of DALYs in 1990 to the 7th leading cause in 2016, representing a 74.5%(95%UI, 42.8%to 93.9%) change. In 2016, each of the following 6 risks individually accounted for more than 5%of risk-attributable DALYs: tobacco consumption, high body mass index (BMI), poor diet, alcohol and drug use, high fasting plasma glucose, and high blood pressure. Across all US states, the top risk factors in terms of attributable DALYs were due to 1 of the 3 following causes: tobacco consumption (32 states), high BMI (10 states), or alcohol and drug use (8 states). Conclusions and Relevance There are wide differences in the burden of disease at the state level. Specific diseases and risk factors, such as drug use disorders, high BMI, poor diet, high fasting plasma glucose level, and alcohol use disorders are increasing and warrant increased attention. These data can be used to inform national health priorities for research, clinical care, and policy.

Purpose Drug-resistant tuberculosis (DRTB) is steadily increasing in Mexico, but little is known of patient risk factors in the Mexico–United States border region. This preliminary case-control study included 95 patients with active pulmonary TB with drug susceptibility results attending the Jose E. Gonzalez University Hospital in the urban hub of Nuevo Leon—the Monterrey Metropolitan Area. We report potential social and clinical risk factors of DRTB among this hospital-based sample. Methods We collected data through face-to-face interviews and medical record reviews from 25 cases with DRTB and 70 drug-sensitive controls. DNA was collected to assess an effect of genetic ancestry on DRTB by using a panel of 291,917 genomic markers. We calculated crude and multivariate logistic regression. Results After adjusting for potential confounding factors, we found that prior TB treatment (odds ratio, 4.5; 95% confidence interval, 0.9–21.1) and use of crack cocaine (odds ratio, 4.6; 95% confidence interval, 1.1–18.7) were associated with DRTB. No other variables, including genetic ancestry and comorbidities, were predictive. Conclusions Health care providers may benefit from recognizing predictors of DRTB in regions where routine drug susceptibility testing is limited. Prior TB treatment and illicit drug use, specifically crack cocaine, may be important risk factors for DRTB in this region.

Obesity may be masking other health problems such as height deficit, or stunting. Stunting may reflect the cumulative effect of chronic malnutrition especially in underserved immigrant communities. Exploratory analysis of a sample of children 2-19 years old from the 2007-2008 NHANES was used to assess the relationship between chronic malnutrition and overweight/obesity in Hispanic children. Overall, overweight/obesity prevalence was nearly 1 in 3 children and stunting prevalence was 3.1%. The prevalence of stunting varied significantly across race/ethnicity, with prevalence among Hispanics of 6.6%. Prevalence of stunting varied significantly by socio-economic characteristics within the Hispanic population. Our exploratory study showed differences in the prevalence of stunting across racial/ethnic groups and highlighted that overweight/obese Hispanic children have a higher prevalence of stunting compared with Non-Hispanic White overweight/obese children. More studies are needed to better understand the phenomenon and the implications for health inequities.

Few studies have examined the effects of in utero exposure to organophosphate and carbamate pesticides on neurobehavioral development in infants and young children. This study considers the potential effects of maternal occupation in the cut-flower industry during pregnancy on neurobehavioral development in Ecuadorian children.Data were collected during 2003-2004 for 121 children aged 3-23 months and living in the rural highland region of Cayambe, Ecuador. Children were administered the Ages and Stages Questionnaire and were given specific developmental tests including prehension (reach-and-grasp) and visual skills. Information was gathered on maternal health and work characteristics, the home environment, and child health status. Growth measurements and a hemoglobin finger-prick blood test were obtained. We conducted multiple linear and logistic regression analyses.Children whose mothers worked in the flower industry during pregnancy scored lower on communication (8% decrease in score, 95% confidence interval [CI]: -16% to 0.5%) and fine motor skills (13% decrease, 95% CI: -22% to -5), and had a higher odds of having poor visual acuity (odds ratio = 4.7 [CI =1.1-20]), compared with children whose mothers did not work in the flower industry during pregnancy, after adjusting for potential confounders.Maternal occupation in the cut-flower industry during pregnancy may be associated with delayed neurobehavioral development of children aged 3-23 months. Possible hazards associated with working in the flower industry during pregnancy include pesticide exposure, exhaustion, and job stress.

OBJECTIVE: To identify and describe the sociodemographic and nutritional characteristics associated with neurobehavioral development among young children living in three communities in the northeastern Andean region of Cayambe-Tabacundo, Ecuador. METHODS: Women in the study communities who had a child 3 to 61 months of age completed a questionnaire about maternal and child health and sociodemographic characteristics. The Ages and Stages Questionnaire (ASQ) was directly administered to 283 children by two trained interviewers. Growth measurements and a hemoglobin finger-prick blood test were obtained in 2003-2004. Prevalence of developmental delay was calculated, and associations between child development and maternal, child, and household characteristics were explored. RESULTS: High frequencies of developmental delay were observed. Children 3 to 23 months old displayed delay in gross motor skills (30.1%), and children 48 to 61 months old displayed delay in problem-solving skills (73.4%) and fine motor skills (28.1%). A high frequency of both anemia (60.4%) and stunting (53.4%) was observed for all age groups. Maternal educational level was positively associated with communication and problem-solving skills, and monthly household income was positively associated with communication, gross motor, and problem-solving skills. CONCLUSIONS: The results suggest a high prevalence of developmental delay and poor child health in this population. Child health status and the child's environment may contribute to developmental delay in this region of Ecuador, but sociodemographic factors affecting opportunities for stimulation may also play a role. Research is needed to identify what is causing high percentages of neurobehavioral developmental delay in this region of Ecuador.OBJETIVOS: Identificar y describir las características sociodemográficas y nutricionales asociadas con el desarrollo neuroconductual en niños pequeños de tres comunidades de la región nororiental andina de Cayambe-Tabacundo, Ecuador. MÉTODOS: Mujeres de las comunidades estudiadas con algún hijo de 3 a 61 meses de edad llenaron un cuestionario sobre sus características, las características de salud de su hijo y las características sociodemográficas. Dos entrevistadores entrenados aplicaron el Cuestionario sobre Edades y Etapas (Ages and Stages Questionnaire, ASQ) directamente a 283 niños. Se midió el crecimiento y se realizó una prueba de hemoglobina mediante punción digital en el período 2003-2004. Se calculó la prevalencia del retraso en el desarrollo y se exploraron las asociaciones entre el desarrollo del niño y las características de la madre, del niño y del hogar. RESULTADOS: Se observaron elevadas frecuencias de retraso en el desarrollo. Los niños de 3 a 23 meses de edad presentaron retraso en las habilidades motrices básicas (30,1%) y los niños de 48 a 61 meses de edad presentaron retraso en las habilidades para solucionar problemas (73,4%) y en las habilidades motrices finas (28,1%). Se encontró una elevada frecuencia de anemia (60,4%) y de retraso en el crecimiento (53,4%) en todos los grupos de edad. Se observó una asociación directa entre el nivel educacional de la madre y las habilidades de comunicación y de solución de problemas de sus hijos, así como entre los ingresos mensuales del hogar y las habilidades de comunicación, las motrices básicas y de solución de problemas. CONCLUSIONES: Los resultados indican que hay una elevada prevalencia de retraso en el desarrollo y una deficiente salud infantil en la población estudiada. El estado de salud del niño y su entorno pueden contribuir al retraso en el desarrollo en esta región de Ecuador, sin embargo, los factores socioedemográficos que afectan negativamente a las oportunidades de estimulación pueden desempañar un papel importante en ello. Se requieren investigaciones que identifiquen las causas del elevado porcentaje de retraso en el desarrollo neuroconductual en esta región de Ecuador.
