Quantitative Assessment of Pubertal Development among Rural and Urban Adolescents in Osun State, Nigeria: A Comparison of Two Standard Instruments
Journal Title: Journal of Medical Science And clinical Research - Year 2014, Vol 2, Issue 6
Abstract
Introduction: Pubertal development is a critical element in adolescents’ life and is affected by several factors. Studies with quantitative assessment of pubertal development of Nigerian adolescents are rare. Concerns about valid and practical assessment of pubertal development have led to the development of several instruments, but the possibility of differences in the rating of the instrument exists. This study compared the pubertal development of rural and urban school-based adolescents in Osun State, Nigeria, Adedayo Sabageh et al JMSCR Volume 2 Issue 6 June 2014 Page 1334 JMSCR Volume||2||Issue||6||Page 1333-1343 ||June 2014 2014 using two widely known instruments – the Pubertal Developmental Scale (PDS) and the Sexual Maturity Scale (SMS). Methodology: The study involved 760 adolescents who were randomly selected through a multistage sampling process from rural and urban secondary schools in Osun state, Nigeria. Data were collected through assisted self-completion questionnaire method, with the research instrument incorporating both SMS and PDS. Data were analyzed using SPSS version 16. Agreement between the pubertal rating of the instruments was determined using Kappa statistics. Comparing of the pubertal rating of adolescents from urban and rural schools were assessed using Chi-square. Statistical significance was set at the 5% level. Results: A total of 389 (51.2%) were males and 371 (48.8%) were females, and half of the participants were from rural areas. The mean age was 14.62 ± 2.39 years. Using PDS, the highest proportion of the participants in both urban (32.6%) and rural areas (35.8%) were in the mid-puberty stage, whereas using SMS, the highest proportion of adolescents were in the late puberty (urban: 36.1%; rural: 32.9%). The level of agreement between PDS and MSMS pubertal rating was poor (Kappa Statistic=0.235). Conclusion: There is a difference in pubertal development of rural and urban school adolescents in Osun State with urban ones attaining puberty earlier. Careful choice of pubertal assessment instruments in clinical practice and adolescent research is warranted in view of the poor agreement between their ratings.
