Locus of control as a predictor of students dropping out of high school

Education is related to health. In cross-sectional data, education level has been associated with physical functioning. Also, lower levels of education have been associated with health behaviors including smoking, alcohol use, and greater body weight. In school, students may benefit from greater exposed to health-related messages, while students who have dropped out may be more susceptible to influences regarding negative health behaviors such as smoking. ^ Improved school retention might improve long-term health outcomes. However, there is limited evidence regarding modifiable factors that predict likelihood of dropping out. Two likely psychosocial measures are locus of control and parent-child academic conversations. In the current study, data from two waves of a population-based longitudinal survey, the National Education Longitudinal Survey, were utilized to evaluate whether these two psychosocial measures could predict likelihood of dropping out, for students (n = 16,749) in tenth grade at 1990, with dropout status determined at 1992, while controlling for recognized sociodemographic predictors including parental income, parental education level, race/ethnicity, and sex. Locus of control was measured with the Pearlin Mastery Scale, and parent-child academic conversations were measured by three questions concerning course selection at school, school activities and events, and things the student studied in class. ^ In a logistic regression model, with the sociodemographic control measures entered in a first step before entry of the psychosocial measures in a second step, this study determined that lower levels of locus of control were associated with greater likelihood of dropping out after two years (odds ratio (OR) = 1.11, 95% confidence interval (CI) 108 to 1.15, p < .001), and two of the three parent-child academic discussion items were associated with greater likelihood of dropping out after two years (OR = 1.69, CI 1.48-1.93, p < .001; OR = 1.22, CI 1.05-1.41, p = .01; OR = 1.01, CI .88-1.15, p = .94). ^ It is possible that interventions aimed at improving locus of control, and aimed at building parent-child academic conversations, could lower the likelihood of students dropping out, and this in turn could yield improved heath behaviors and health status in the child's future. ^

Attention-Deficit/Hyperactivity Disorder and antidepressants and prescription medications: A pilot study

Background. Attention Deficit-Hyperactivity Disorder (AD/HD) diagnosis in children and adolescents has been on the rise over the last couple of decades and a multitude of studies have been conducted in an aim to better understand the disease. Literature has explored the role of several factors suspected of contributing to development of the disease, including: prenatal smoking exposures, environmental exposures, and low-birth weight. However, there is very limited reporting of fetal/infant exposure to antidepressants and prescription medications and the long-term behavioral outcomes, namely development of AD/HD. The purpose of this study was to evaluate the relationship between mother's exposure to prescription medications and/or antidepressants around the time of conception, during pregnancy, or while breastfeeding and the development of Attention-Deficit/Hyperactivity Disorder in offspring. Methods. Secondary analysis of data from a case-control study was performed. Exposure histories were collected for the mother and offspring. Data were collected using a secure, confidential, self-report, online survey to evaluate the relationship between antidepressant and/or prescription medication exposure and the development of AD/HD. The period of exposure to these drugs was defined as: around the time of conception, during pregnancy, or while breastfeeding. Cases were defined as a child who had been diagnosed with AD/HD. Controls were defined as a child who had not been diagnosed with AD/HD. Results. Prescription medication and antidepressant medication exposures around the time of conception, during pregnancy, or while breastfeeding were not associated with development of AD/HD. However, traumatic brain injury (OR=2.77 (1.61–4.77)) and preterm birth (OR=1.48 (1.04–2.12)) were identified as potential risk factors. These results support existing literature on AD/HD, but future work must be undertaken to better evaluate fetal/infant medication exposures and long-term behavioral outcomes.^

Vitamin A supplementation in very low birth weight infants

PURPOSE: In United States, the percentage of Extremely Low Birth Weight (ELBW) born for year 2006 was 0.8% (approximately 32,000 babies) & Very Low Birth Weight (VLBW) 1.48% (1). ELBW babies account for nearly half (49%) of the infant mortality for United States. Very Low birth weight infants are at a significant risk for high mortality and morbidity due to their multi system involvement and predisposition to lung prematurity and impaired immune function. One of the common causes cited is Vitamin A deficiency (2, 3).The purpose of this study is to look at published literature on Vitamin A supplementation in very low birth weight (VLBW) infants. ^ RESEARCH DESIGN: Systematic review of literature of published articles meeting the pre-defined criteria. ^ PROCEDURE: Studies included in this review were those which looked at very low birth weight infants defined as birth weight<1500gms. All experimental studies were reviewed. Studies looking at the effect of Vitamin A supplementation in comparison with a placebo or by itself in varying dosing regimens as an intervention were reviewed. Vitamin A deficiency and its manifestations were of interest. We used key words such as "very low birth weight", "mortality", "Vitamin A", "retinol" and "supplementation" in our search. ^ RISKS & POTENTIAL BENEFITS: We do not see any potential risks associated with this study. The potential benefit is recommendation for future studies based on the review of literature available currently. ^ IMPORTANCE OF KNOWLEDGE THAT MAY REASONABLY BE EXPECTED TO RESULT: The systematic review of literature of all experimental studies in VLBW infants showed uniform correlation of parenteral Vitamin A dosing and high plasma concentrations achieved. The recommended dosage for use is 5000 IU 3 times/week given intramuscularly for 4 weeks to prevent CLD. Higher doses have not shown benefit, with a potential for toxicity, while lower doses are inadequate. There is no role of use of Vitamin A in closure of patent ductus arteriosus & reducing mortality. However, it is important to state that the number of studies done so far is limited with small sample sizes. There is a need in the future for experimental studies to ascertain the role of Vitamin A to improve outcomes in VLBW. Atleast, one more RCT should be conducted using the dosage recommended above to make this a standard practice.^
