“…Despite adolescence being a particularly significant stage of development, research on the impacts of stressors on adolescent mental and physical development are limited (5). Studies on Sri Lankan children and adolescent cognitive development to date have focused on stress and its association with nutritional status, inadequate cognitive stimulation, iodine deficiency and iron deficiencies (8,9). This study thus attempts to provide better understanding of the psychosocial factors that contribute to stress amongst adolescents aged 14 to 16 years living in the Colombo District, Sri Lanka.…”

Introduction:In Sri Lanka, adolescents comprise 16.1% of the population. Stress during adolescence may impact maturation of emotional and cognitive capabilities. The objective of the study is to determine the psychosocial factors and other factors that contribute to stress amongst adolescents aged 14 to 16 years living in the Colombo District, Sri Lanka. Methods:A descriptive cross-sectional study was conducted on adolescents aged 14 -16 years (n = 331) from randomly selected schools in the Colombo District, Sri Lanka. A self-administered questionnaire was used to collect baseline socioeconomic data. Baseline anthropometric measurements of height and weight were measured and BMI was calculated. Adolescent stress was assessed by using the Adolescent Stress Questionnaire (ASQ). Results:In the current study, 179 (54.1%) adolescents were males. The mean ages of male and female adolescents and their social characteristics were similar. There was a statistically significant increase in the mean height (p<0.001) and mean weight (p<0.001) of male adolescents when compared with female adolescents. The mean total stress scores of female and male adolescents were similar (p = 0.063). The mean score of stress of home life of female adolescents was significantly higher than male adolescents (p<0.001). The mean score of stress of school attendance was significantly higher among male adolescents than female adolescents (p = 0.012). Conclusions & recommendations:Both male and female adolescents experience considerable stress. Measures to overcome preventable stressors should be implemented at school and at home by parents, teachers and education administrators.

“…The estimated full scale intelligence quota (EFSIQ) was calculated based on the sum of the eight subtest scores. WISC profile has been validated in Sri Lanka and used in previous national studies 17 . TONI-3 is free of language and culture bias and an objective method of examining cognitive function which does not require verbal or motor skills.…”

Introduction: The brain undergoes dynamic structural and maturational changes during adolescence, producing significant changes in cognition and behaviour. Cognitive performance (CP) of an individual is influenced by many factors, nutritional, psychosocial and genetic. Objectives: To determine the influence of nutritional and psychosocial factors on CP of early female adolescents in Sri Lanka. Method: Two hundred and eighteen female adolescents, 11-14 years of age, were administered neurocognitive test batteries comprising tests of nonverbal intelligence, subtests of Wechsler Intelligence Scale for Children and two computer based executive function tests to assess CP. Height for age Z-score (HAZ), weight for age Z-score (WAZ) and BMI for age Z-score (BAZ) were calculated to measure nutritional status. Adolescent stress questionnaire (ASQ) was used to assess stress.
