ABSTRACT
@#Introduction: Among adolescents, asthma is an important public health burden that is associated with high morbidity and mortality. Poor asthma control is likely in this age group. Our aim was to identify the predictors of well controlled asthma among adolescents with persistent asthma in Northwest of Libya. Methods: A sample of 92 adolescents with persistent asthma were recruited from the respiratory clinic in Sabratha Teaching Hospital, and completed questionnaires measuring demographic and clinical characteristics, asthma knowledge, self-efficacy, and asthma control. Logistic regression analysis was carried out, taking the asthma control as the dependent variable. Results: Twenty-four percent of participants had well controlled asthma. In a bivariate analysis, well controlled asthma was significantly associated with adolescents having mild persistent asthma, not having allergic rhinitis, using preventive inhalers regularly, reporting higher level asthma knowledge, and higher self-efficacy. However, in multiple logistic model, only self-efficacy was an independent predictor of asthma control, with higher self-efficacy associated with well-controlled asthma (Adjusted OR= 1.107, 95% CI: 1.012 – 1.210, p= 0.026). Conclusion: Identifying and targeting modifiable predictors of well controlled asthma could improve asthma control. In adolescents with asthma, enhancing self-confidence of adolescents to undertake health behaviour modification seems to be an important step toward a better asthma control.
ABSTRACT
Though cases of AIDS are visible in Nigeria and awareness of HIV is high, correct knowledge on HIV transmission and prevention has remained low with significant numbers of people living with HIV/AIDS having low attitudes towards life and the disease itself. This study determined the baseline knowledge on HIV transmission and prevention, and attitudes towards HIV/AIDS of adult HIV positive patient enrolled into care at all four comprehensive antiretroviral therapy (ART) sites in Yola, Nigeria. Baseline reports on the knowledge and attitudes of adult HIV positive patients were obtained from a three arm randomized single blind clinical trial involving 386 randomly selected adult HIV patients who were enrolled into ART care at all four comprehensive ART sites in Yola. An administered, validated structured questionnaire was used for data collection. Outcome measures were sound knowledge on HIV transmission and prevention, and attitudes towards HIV/AIDS. Data was analyzed using SPSS version 22. Test of significance was at α level 0.05. Overall 237 (61.4%) had sound knowledge on HIV transmission and prevention, while 346 (89.6%) of respondents had high attitudes towards HIV/AIDS. Though majority of respondents had sound knowledge on HIV transmission and prevention as well as high attitudes towards HIV/AIDS, interventions to improve knowledge and attitudes among this group of individuals would improve positive preventive strategies.

Studies on diet quality among individuals with type 2 diabetes mellitus (T2DM) are scarce. This crosssectional study aimed to assess the diet quality and to determine its associated factors among individuals with T2DM at the Medical Outpatients Department, Serdang Hospital, Selangor, Malaysia, from July 2010 to March 2011. Subjects were interviewed for sociodemographic data. Diabetes history was retrieved from the hospital’s e-database. Usual dietary intake was measured using a food frequency questionnaire, from which a dietary diversity score was obtained with two measures: Food Group Score and Serving Score were constructed based on the Malaysian Dietary Guidelines. Food Group Score was computed from the number of food groups consumed from five major food groups (grains, vegetables, fruits, meat, and dairy products) whereas Serving Score was computed from the number of servings consumed from the various food groups. Anthropometric measures, including weight, height, waist- and hip-circumference were examined. For data analyses, descriptive statistics, simple and multiple linear regression were conducted using IBM SPSS Statistics 20.0. A total of 113 subjects (50.4% female), with mean±SD age of 54.05±10.30 years and duration of diabetes of 11.25±9.05 years were studied. The mean Food Group Score and Serving Score were 4.12±0.79 and 12.75±3.50 respectively. Slightly more than one-third of the subjects achieved five food groups a day while less than 2% consumed a desirable number of servings from all food groups. Among the five food groups, dairy, and fruits were the least-frequently consumed foods. Lower education, lower personal income, working, non-insulin, overweight and obese subjects had significantly lower Food Group Score than their counterparts [F (6,106)=4.924, p<0.0001] whereas lower education, lower waist-to-hip ratio, overweight and obese subjects had significantly lower Serving Score than their counterparts [F (4,108)=7.520, p<0.0001]. There was a high proportion of individuals with T2DM, who failed to adhere to the national dietary guidelines. The importance of taking a well-balanced diet in accordance with the guidelines should be emphasized, especially among those with lower educational level through a simple and easy-to-understand approach.
ABSTRACT
INTRODUCTION: Menarche or first menstrual period is a landmark in reproductive life span and it is the most prominent change of puberty. The timing of menarche can be under the influence of genes as well as individual environmental factors interacting with genetic factors. OBJECTIVE: Our study objectives were (a) to investigate the heritability of age of menarche in twins, (b) to obtain the association between age of menarche and childhood factors, and reproductive events/behavior, (c) to examine whether or not having a male co-twin affects early/late menarche. METHODOLOGY: A group of female-female identical (n = 108, 54 pairs), non-identical twins (n = 68, 34 pairs) and 17 females from opposite-sex twin sets were identified from twin registries of Malaysia and Iran. Genetic analysis was performed via two methods of Falconers’ formula and maximum likelihood. RESULTS: Heritability was found to be 66% using Falconers’ formula and 15% using univariate twin analysis. Model analysis revealed that shared environmental factors have a major contribution in determining the age of menarche (82%) followed by non-shared environment (18%). DISCUSSION: Result of this study is consistent with that of the literature. Timing of menarche could be under the influence of shared and non-shared environmental effects. Hirsutism was found to have a higher frequency among subjects with late menarche. There was no significant difference in age of menarche between females of opposite-sex twins and females of same-sex twins. CONCLUSION: It is concluded that twin models provide a powerful means of examining the total genetic contribution to age of menarche. Longitudinal studies of twins may clarify the type of environmental effects that determine the age of menarche.

The antibody levels to viral capsid antigen (VCA) and early antigen (EA) of Epstein-Barr virus (EBV) in 164 nasopharyngeal carcinoma (NPC) patients from Sarawak, East Malaysia were significantly higher than those in 147 sex, age and ethnically matched healthy controls. As diagnostic markers of NPC, IgG/VCA at reciprocal titers > or =160 was the most sensitive (89%, with 98% specificity), while IgA/EA at > or =5 was the most specific (100%) but the least sensitive (75%). The sensitivity and specificity of IgA/VCA at reciprocal titers > or =10 were 84% and 97%. IgA/VCA has an advantage over IgG/VCA despite the slightly lower sensitivity due to its consistently more distinct fluorescence reaction. The sensitivity and specificity can be marginally improved by a combination of two tests.
