ปัจจัยที่มีความสัมพันธ์กับการกลับเป็นซ้ำของโรคเหา ในเด็กนักเรียนหญิง ระดับประถมศึกษาตอนต้น จังหวัดมหาสารคาม

Abstract

        Head lice is another problem that can occur among students. Having a persistent head lice problem and head lice relapse can inhibit the learning efficiency of students. This Case-Control study was conducted in order to investigate the factors that allow the relapse of head lice problems among the student girls. The samples were 246 parents of the targeted students, who had been classified into two groups: 1) the Case Group consisted of 123 parents, who used to apply Benzyl benzoate to eliminate head lice and whose children faced the return of the hair head lice within 1 year, and 2) the Control Group consisted of 123 parents, who had applied Benzyl benzoate to eliminate head lice and whose children, within 1 year, had not experienced any relapse of head lice problems. The data collection was done via interviews. Data were subsequently analyzed using multiple logistic regression analysis, and correlations are presented with adjusted odds ratios (OR_adj), 95% confidence intervals (95% CI), and p-values. 

        The parental factors that were found to have a significant association with the head lice relapse  problem had consisted of the following: 1) having long hair (OR_adj = 9.79, 95% CI = 2.47-38.80, P-value = 0.002), 2) not using a head lice-repellent shampoo (OR_adj = 31.71, 95% CI = 11.7-85.95, P-value < 0.001), 3) having an average monthly income of 8000 Baht or lower (OR_adj = 5.97, 95% CI = 2.44-14.61, P-value < 0.001), and 4) having poor practices to prevent the return of head lice problems (OR_adj = 7.25, 95% CI = 3.25-16.14, P-value < 0.001).

        It is suggested that the parents and teachers collaborate to care for the students’ health. Specifically, there should be a weekly hair and scalp examinations and head lice-repellent shampoos should be applied for the long hair lower-primary grade school students.
