Receipt of Corrective Lenses and Academic Performance of Low-Income Students.

ABSTRACT:

Objective

Untreated vision problems are associated with poor school performance. Whether providing glasses alone improves performance, however, remains unknown. We sought to test whether receiving glasses was associated with improved school performance for low-income minority students in Los Angeles.

Methods

From 2017 to 2018, we analyzed achievement marks in mathematics and language arts from 406 first to fifth grade students attending 24 public elementary schools who received glasses through a free school-based vision program between February and May 2014, and 23,393 of their nonparticipating same-school, same-grade peers. We calculated students' percentile rank during each grading period in 1 year before and 2 years since they received glasses. Multilevel linear regressions tested whether percentile rank differed from baseline at each subsequent grading period. Models accounted for clustering at the school level and controlled for gender, grade level, and baseline class rank. Interaction terms tested whether associations differed by gender and class rank.

Results

Students increased 4.5 percentile points (P = .02) in language arts in the second year after receiving glasses. There was no change in math achievement overall; however, those with baseline performance in the bottom tercile had an immediate and sustained improvement of 10 to 24 percentile points from baseline (interaction term P < .001). Class rank for behavior marks decreased during the fourth grading period after receiving glasses but subsequently returned to baseline. There were no significant changes in work habits and no variation in results by gender.

Conclusions

Ensuring access to vision care may be a simple, scalable strategy to improve language arts performance for low-income minority children.

Project description:BackgroundWhile several individual studies addressing research productivity of post-graduate students are available, a synthesis of effective strategies to increase productivity and the determinants of productivity in low-income countries has not been undertaken. Further, whether or not this research from post-graduate students' projects was applied in evidence-informed decision-making was unknown. Therefore, we conducted a systematic review of literature to identify and assess the effectiveness of approaches that increase productivity (proportion published) or the application (proportion cited) of post-graduate students' research, as well as to assess the determinants of post-graduate students' research productivity and use.MethodsWe conducted a systematic review as per our a priori published protocol, also registered in PROSPERO (CRD42016042819). We searched for published articles in PubMed/MEDLINE and the ERIC databases through to July 2017. We performed duplicate assessments for included primary studies and resolved discrepancies by consensus. Thereafter, we completed a structured narrative synthesis and, for a subset of studies, we performed a meta-analysis of the findings using both fixed and random effects approaches. We aligned our results to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.ResultsWe found 5080 articles in the PubMed (n = 3848) and ERIC (n = 1232) databases. After excluding duplicates (n = 33), we screened 5047 articles, of which 5012 were excluded. We then retrieved 44 full texts and synthesised 14, of which 4 had a high risk of bias. We did not find any studies assessing effectiveness of strategies for increasing publication nor citations of post-graduate research projects. We found an average publication proportion of 7% (95% CI 7-8%, Higgins I-squared 0.0% and Cochran's Q p < 0.01) and 23% (95% CI 17-29%, Higgins I-squared of 98.4% and Cochran's Q, p < 0.01) using fixed effects and random effects models, respectively. Two studies reported on the citation of post-graduate students' studies, at 17% (95% CI 15-19%) in Uganda and a median citation of 1 study in Turkey (IQR 0.6-2.3). Only one included study reported on the determinants of productivity or use of post-graduate students' research, suggesting that younger students were more likely to publish and cohort studies were more likely to be published.ConclusionsWe report on the low productivity of post-graduate students' research in low- and middle-income countries, including the citation of post-graduate students' research in evidence-informed health policy in low- and middle-income countries. Secondly, we did not find a single study that assessed strategies to increase productivity and use of post-graduate students' research in evidence-informed health policy, a subject for future research.

Project description:BackgroundSleep disorders are composed of a group of diseases of increasing prevalence and with social-health implications to be considered a public health problem. Sleep habits and specific sleep behaviors have an influence on the academic success of students. However, the characteristics of sleep and sleep habits of university students as predictors of poor academic performance have been scarcely analyzed. In the present study, we aimed to investigate sleep habits and their influence on academic performance in a cohort of Nursing Degree students.MethodsThis was a cross-sectional and observational study. An anonymous and self-administered questionnaire was used, including different scales such as the 'Morningness and Eveningness scale', an author-generated sleep habit questionnaire, and certain variables aimed at studying the socio-familial and academic aspects of the Nursing students. The association of sleep habits and other variables with poor academic performance was investigated by logistic regression. The internal consistency and homogeneity of the 'sleep habits questionnaire' was assessed with the Cronbach's alpha test.ResultsOverall, 401 students (mean age of 22.1 ± 4.9 years, 74.8 % females) from the Nursing Degree were included. The homogeneity of the 'sleep habits questionnaire' was appropriate (Cronbach's alpha = 0.710). Nursing students were characterized by an evening chronotype (20.2 %) and a short sleep pattern. 30.4 % of the Nursing students had bad sleep habits. Regarding the academic performance, 47.9 % of the students showed a poor one. On multivariate logistic regression analysis, a short sleep pattern (adjusted OR = 1.53, 95 % CI 1.01-2.34), bad sleep habits (aOR = 1.76, 95 % CI 1.11-2.79), and age < 25 years (aOR = 2.27, 95 % CI 1.30-3.98) were independently associated with a higher probability of poor academic performance.ConclusionsAlmost 1/3 of the Nursing students were identified as having bad sleep habits, and these students were characterized by an evening chronotype and a short sleep pattern. A short sleep pattern, bad sleep habits, and age < 25 years, were independently associated with a higher risk of poor academic performance. This requires multifactorial approaches and the involvement of all the associated actors: teachers, academic institutions, health institutions, and the people in charge in university residences, among others.

Project description:UnlabelledBackground. Little research exists on the impact of paid work on academic performance of students of health sciences. No research exists on this subject for students in Colombia. Objectives. This paper seeks to analyze the impact of paid work on academic performance among nursing students.Design, settings and participantscross-sectional research, involving 430 of nursing students from the National University of Colombia (N = 566). Methods. Variables analyzed: sex, age, work activity, attendance, current semester, degree subjects studied and unavailable, lost credits, grades during the second semester of 2013, and delayed semesters. Subgroups analyzed: (i) according to labor activity: do not work, work up to 20 h and work more than 20 h per week; (ii) Grade point average: failing is considered as less than 3.0 and passing 3.0 or above out of 5.0. Percentage of delayed semesters were calculated. Qualitative and quantitative variables were analyzed for groups by work activity. The percentage and probability of students getting a grade point average less than 3.0 and delaying semesters were calculated by multivariate logistic regression. Results. A total of 219 of the students work (50.9%), the main reason is socioeconomic, of which 99 (45.2%) work more than 20 h per week and have an increased risk of failing, which is higher in the first semester. They also get lower grades, lose more credits and take longer to finish the degree. The logistic bivariate regressions of success (grade point average, credits gained, courses gained and not having delayed semesters) reduce with work, above all in those who work more than 20 h per week and increase as the number of semesters completed increases, independent of sex. Conclusion. A high percentage of nursing students work more than 20 h per week. The compatibility of paid work with studies in university nursing students has a negative impact on academic performance, more so when they work more than 20 h per week. This negative impact diminishes as the student completes semesters, irrespective of the sex of the students.
