Susceptibility to smoking, which is defined as a lack of cognitive commitment not to smoke in the future, has been shown to be a predictor for adolescent smoking initiation in developed countries. This study aims to evaluate the utility of a susceptibility-to-smoke measure as a predictor of smoking initiation among adolescents in Kota Tinggi district, Johor Malaysia. Susceptibility to smoking was evaluated among 1763 adolescents at baseline using a two-item construct. At follow-up 12 months later, 1288 of the 1763 adolescents (73.1%) responded. Results showed 14.9% (n=188/1260) of the respondents were susceptible to smoking at baseline. Among the susceptible adolescents, 31.9% initiated smoking after one year. Respondents who were identified as susceptible to smoking by the measure were 3.7 times (95%; CI: 2.17- 6.30) more likely to initiate smoking compared to non-susceptible respondents after adjusting for gender, school locality, percentage of friends who smoke, father smoking, parental acceptance of smoking, and belief in the positive and negative consequences of smoking. The findings suggest that the susceptibility measure is a reliable predictor and can be used as a screening tool to identify adolescents who are at risk of initiating smoking.

A Number of studies have found the cases of facilities in public buildings which are inaccessible by users & visitors with different abilities. Thus, constructing user friendly and barrier-free architecture-interior design is necessary in the built environment. This research will evaluate the requirements for ease of access in public mosques with study cases Pusdai Mosque & Grand Mosque of Bandung in accordance with the Regulation of the Ministry of Public Works and Public Housing of the Republic of Indonesia No.14 2017. The regulation which stipulates the provision of facilities in buildings and environments that suit the needs of all age groups, conditions of physical; mental; and intellectual; or sensory limitations based on the buildings’ function to provide user and visitor convenience in doing activities in the buildings. Both mosques, the Pusdai Mosque and Grand Mosque have not entirely fulfilled the standards of universal design in the interior in term of ease of access, safety and autonomy of space use, safety and security for all. From 7 universal design standard requirements, both mosques of study case only fulfill less than 50% of the requirements

Physical inactivity is strongly associated with obesity and an increased risk of cardiovascular disease in children and adolescents. A cross-sectional study using multistage random sampling was conducted to determine associations between demographic characteristics, sedentary behaviours and physical activity among adolescents. Data were collected from 785 (414 males and 371 females) Form four students attending 15 schools in Petaling District, Selangor using an adapted self-administered questionnaire. Results showed that more females (50.1%) were physically inactive compared to males (39.6%) (Adjusted odds ratio (OR): 1.55, 95% confidence interval (CI): 1.12-2.15). Physically inactive adolescents were less likely to participate in intramural/house league sports (OR: 1.71, 95% CI: 1.19-2.44), school team sports (OR: 1.45, 95% CI: 1.03-2.04) and individual physical activities outside school (OR: 1.53, 95% CI: 1.11-2.12) compared to their physically active counterparts. Physically inactive adolescents were also less engaged in sedentary activities, such as television watching (OR: 0.69, 95% CI: 0.50-0.94), playing computer/video game (OR: 0.44, 95% CI: 0.28-0.72), talking on the telephone/mobile phone text messaging (OR: 0.47, 95% CI: 0.32-0.69) and reading (OR:0.45, 95% CI: 0.24-0.86) compared to those who were physically active. In this study, physical activity coexists with sedentary behaviour in adolescents. Sedentary activities may not necessarily displace physical activity among youth. In addition, these data suggest that promoting organised sports in school and outside the school among youths may be a potential strategy for increasing physical activity in this population.

Social norms, though an important contributing factor of adolescent smoking in developed countries, has not been extensively studied in Malaysia. The objective of this study was to determine the association between certain perceived norms regarding smoking with smoking status among Malaysian secondary school students in Kota Tinggi, Johor. Data were collected from 2311 respondents consisting of 1379 male and 923 female secondary school students in Kota Tinggi district via a self administered questionnaire. Five perceived norms regarding smoking were assessed, namely: perceived peer smoking prevalence, perceived parental reaction towards adolescent smoking, perceived public perception of adolescent smoking, ever noticed peers smoking inside and outside school and perceived enforcement of anti-smoking policy in school and their association with smoking status. Multiple logistic regressions controlling for gender, peer smoking and family smoking was performed. Of the five perceived norms, four were associated with smoking status, (perceived peer smoking prevalence (p<0.001value), ever seen friends smoking inside or outside school (p <0.001), perceived parental reaction towards adolescent smoking (p<0.001 value) and perceived public disapproval (p <0.001)). Higher odds for smoking was observed for adolescents who: perceived a few (aOR 3.22), many (aOR 3.01) or a lot (aOR 3.52) of their peers smoke; had ever observed friends smoking in or outside of school (aOR 1.79); perceived their parents will react badly to smoking (aOR 0.84) or perceived the public disapprove of smoking (aOR 0.93). These results suggest that perception of social norms influence adolescents’ decision to smoke, thus measures to curb smoking incidence amongst adolescents should address these perceptions of social norms.

Many studies on adolescent smoking have been conducted in Malaysia, but very limited information is available on smoking amongst lower secondary school male students (Forms 1 and 2). We present data from a baseline study in Kota Tinggi District, Johor on the psychosocial factors, stages of smoking acquisition and susceptibility to smoking initiation and their relationship to adolescent smoking. The study is the first wave of a 3-year longitudinal study which was conducted from March 2007 to May 2009, aimed to describe the prevalence of smoking among students in the lower secondary classes. A three stage stratified sampling was performed to obtain a sample. The Bogus Pipeline Method was employed to confirm smoking status. Prevalence of smoking was 35.5%. Smoking prevalence among students of schools located in the Federal Land Development Authority (FELDA) settlement areas (42.9%) was two-fold higher than in the rural and town schools combined (20.29%). Using the Fagerstrom scale, 90% of current smokers had lower addiction to nicotine. Smoking was associated with peer smoking [OR, 4.19 (95% CI, 2.57-6.82)], having a brother smoking [2.17 (1.31-3.61)], parental smoking [1.73 (1.17-2.80)] and locality where respondents attend school [1.94(1.11-3.39)]. The study indicates that, the prevalence of smoking was high in all areas especially FELDA settlement areas. Measures such as teaching of skills to resist social pressure to smoke, establishment of peer support groups and involvement of parents in anti-smoking programs are recommended to curb the high prevalence of smoking among lower secondary school students in Kota Tinggi.

Childhood obesity is an established problem in many countries and emerging in others. Epidemiological data on obesity in children is essential in order to plan public health policy and services. A study was conducted to determine the prevalence of obesity in schoolchildren in the fifth grade of elementary school (10-12 years old) in the district of Kuala Selangor. Ten schools of which five are in urban and five in rural areas were selected consisting of 699 eleven year old schoolchildren from the three major ethnic groups. Using international cut-off points for obesity, we report an overall prevalence of obesity of 7.2%. Prevalence of obesity in urban children is 7.2% whereas in rural children it is 7.0 %. Analysed by gender, there were 8.9% obese boys and 5.3% obese girls. Among the 3 major ethnic groups, the Malays had the highest prevalence of obesity at 9.3% followed by the Chinese with 6.6% while among Indians 3.0%. The data obtained from this study suggests that obesity in Kuala Selangor children is a cause for concern in urban and rural areas.

Adolescents who overestimate the prevalence of smoking among their peers or other teens are at higher risk to take up smoking. The purpose of this study is to elucidate the factors which are related to adolescents’ overestimation of smoking. We surveyed form four (16 years old) students in Petaling District, Selangor. A sample was selected using two-stage stratified sampling, and data were collected using standardised, self-administered questionnaires. A response rate of 80.4% (n=1045/1298) was obtained, and a total of 943 students were included in the final analysis. About 73 percent (n=688/943) of the respondents overestimated the prevalence of smoking among their peers. The odds of overestimating increased as the number of close friends who smoke increased [Two close friends, OR=3.10(1.67-5.75), three close friends OR=10.81(4.44-26.3) and four-five close friends OR= 12.91(5.31-31.43)]. Those who had an elder brother who smoked (OR=1.95 (1.18-3.24)) and females [2.08(1.37-3.33) were more likely to overestimate peer smoking prevalence. Intervention programmes to correct the misperception of peer smoking prevalence are recommended, in addition to measures to modify the other factors that are amenable to intervention, so as to reduce the risk of smoking initiation among adolescents.

Introduction: Geographical conditions may be linked with food insecurity and growth retardation in young children. This research assessed household food insecurity status and undernutrition in different geographical areas. Methods: A cross-sectional study was conducted in four different types of geographical areas: coastal, limestone, agricultural and municipality, which were purposely selected in East Java Province. The samples were households with children aged below 5 years. A total of 736 households that fulfilled the inclusion criteria were recruited. Household food security was assessed using the Household Food Security Supplement Measure (US-HFSSM) adapted for developing countries. Nutritional status of children was determined and classified according to World Health Organization Growth Standard (2006). Results: Prevalence and severity of household food insecurity differed significantly among the different geographical areas. Almost half (44.8%) of the households were categorised as “food insecure without hunger”. Prevalence of “hunger” was highest in coastal (7.2%) and limestone areas (5.3%). Highest prevalence of stunting was in coastal areas (11.6%), whereas highest prevalence of wasting (6.2%) and underweight (8.9%) were in limestone areas. Prevalence of undernutrition was relatively low among children living in municipalities. The differences in the distribution of undernutrition of young children and household food insecurity status were statistically associated with the types of geographical areas. Conclusion: Prevalence of household food insecurity differed according to the types of geographical areas in East Java. Prevalence of household food insecurity and young child undernutrition were greater for households in the coastal and limestone areas, compared to those in the agricultural and municipality areas.

Mesosomes of Staphylococcus aureus ATCC 25923 treated with antibiotics were examined morphologically under the electron microscope. The Transmission Electron Microscope Rapid Method was used to eliminate the artifacts due to sample processing. Mesosomes were seen in all the antibiotic treated bacteria and not in the control group. The main factor that contributes to the formation of mesosomes in the bacteria was the mode of action of the antibiotics. The continuous cytoplasmic membrane with infolding (mesosomes) as in the S. aureus ATCC 25923 is therefore confirmed as a definite pattern of membrane organization in gram positive bacteria assaulted by amikacin, gentamicin, ciprofloxacin, vancomycin and oxacillin antibiotics. Our preliminary results show oxacillin and vancomycin treated bacteria seemed to have deeper and more mesosomes than those treated with amikacin, gentamicin and ciprofloxacin. Further research is needed to ascertain whether the deep invagination and the number of mesosomes formed is associated with the types of antibiotic used.
