During the 5-day camp, twenty-seven participants (mean age 15.6 +/- 2.1 years, mean duration 6.3 +/- 3.0 years) were taught diabetes self-management education (DSME) and engaged in psychosocial support sessions. Post-camp activities were held every 3 months and participants were followed for 12 months post-camp. Glycemic control was assessed prior to the camp, then every 3 months. Knowledge level was assessed prior to the camp, at the end of the camp, and every 3 months. Diabetes self-care behavior and quality of life were evaluated prior to the camp, at 3 months and 12 months after the camp. After attending the camp, participants had improvement in knowledge but there were no changes in HbA1c levels or quality of life scores. Quality of life was not consistently associated with HbA1c. In general, participants did not perceive their quality of life was poor or feel having diabetes affected their social life. The issue participants worried about most was whether they would develop complications from diabetes. There were several weak points found among participant self-care behavior, particularly in diet-related matters. Despite no improvement in glycemic control, participants gained knowledge from attending the camp. Diet related self-care behavior is difficult for teenagers with T1D to be compliant.</p>","PeriodicalId":520816,"journal":{"name":"The Southeast Asian journal of tropical medicine and public health","volume":" ","pages":"172-84"},"PeriodicalIF":0.2,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30989870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to examine predictors of family care behavior by family caregivers of children with thalassemia. Eighty-eight family caregivers for children with thalassemia aged 1-16 years were recruited by purposive sampling from in-patient and out-patient clinics in an eastern regional hospital in Thailand. Research instruments were 5 self-administered questionnaires: 1) demographics of family caregivers, 2) perceived family management, 3) medical adherence, 4) health literacy, and 5) family management behavior. Data were analyzed by percentages, means, standard deviations, Pearson's product moment correlation and multiple regression. The strongest predictor for family management behavior was perceived family management (B = 0.550, p < 0.001), it accounted for 26.3% of the variance. Health literacy (B = 0.337, p = 0.024) accounted for 4.5% of the variance. When these two dependent measures were combined, they accounted for 30.8% of the variance (R2 = 0.308, F = 18.933, p < 0.001). Within the three subscales of family management behavior (medical, role, and psychosocial management), medical adherence, health literacy and perceived family management, together accounted for 22.6% of the variance for medical management. Perceived family management and health literacy together accounted for 30.3% of the variance in role management.
