Background: Mental illness have been largely ignored or neglected because of a community's perception and attached social stigma. Materials and Methods: A community based cross-sectional study was conducted in an urban community in South Delhi to study perception and attitude of the community about towards mental illness. An adult member in household selected by systematic random sampling was interviewed using semi-structured interview schedule for perception about mental illness and 34 item Opinion about Mental Illness for Chinese Community (OMICC) scale Results: A total of 100 adults were interviewed. Mean age of the participants was 35.8 (SD: 12.6) years. Living without tension and satisfaction in routine life were identified as indicators of healthy mental status. Change in the behavior was perceived as the most common symptom of mental illness. Although mental stress was identified as the most common cause of mental illness, 25% attributed it to evil spirits. Keeping surroundings friendly and sharing problems with others were identified as - important preventive measures against mental illness. Mental illness was perceived as treatable; 12% preferred treatment from Tantric/Ojha. Community showed negative attitude for stereotyping, restrictiveness, and pessimistic prediction domains of OMICC scale with mean score of 4.5 (SD: 0.2), 3.9 (SD: 0.9), and 3.8 (SD: 0.4), respectively, with no statistically significant difference across age, sex, and literacy. Conclusion: Study observed lack of awareness regarding bio-medical concept of mental illness with socially restrictive, stereotyping, pessimistic, and non-stigmatizing attitude toward mental illness in the capital city.

Background & objectives: The metabolic syndrome (MS) is a risk factor for development of cardiovascular disease and is closely associated with obstructive sleep apnoea (OSA). Co-occurrence of both OSA and MS is called syndrome Z. It has been hypothesized that the OSA may be a manifestation of MS. We collected data on polysomnography (PSG) and biochemical investigations on middle aged urban Indians during a community, based study in South Delhi while studying prevalence of obstructive sleep apnoea and analysed to find out the ages at which the OSA, MS and syndrome Z exist in these subjects. Methods: A 2-stage, cross-sectional, population-based study in subjects of either gender between 30-65 yr of age in 4 different socio-economic zones of the South Delhi, India, was performed earlier (from April 2005 through June 2007). In-hospital, supervised PSG studies were performed and biochemical investigations for the MS using National Cholesterol Education Programmme Adult Treatment Panel (NCEP ATP) III criteria were carried out. In this communication, the data were further analysed to estimate the prevalences of MS alone, OSA alone and syndrome Z and average ages of 3 conditions. Results: Three hundred and fifty one subjects had satisfactory PSG studies. The MS alone was present in 105 129.9%: (95% CI 25.1-34.7)] while OSA alone was present in 24 [6.8%; (95% CI 4.2-9.5)] subjects and the syndrome Z was present in 70 [19.9%; 05% CI 15.8-24.1)] subjects. Median ages of normal subjects, and subjects with MS, OSA and syndrome Z were 40, 43, 43 and 47 yr respectively. Minimum ages of normal subjects, and subjects with MS. OSA and syndrome Z were 30, 30, 32 and 32 yr respectively. Interpretation & conclusions: When body mass index (BMI) was normal, the increasing median ages of these conditions indicated that the MS may be the first event followed by OSA and eventually syndrome Z develops. With BMI >25 or >30 no clear-cut difference was noted, indicating that the BMI itself could have an independent role in MS, OSA and syndrome Z. [ABSTRACT FROM AUTHOR]

Abstract: Background: The epidemiology of obstructive sleep apnea (OSA) and obstructive sleep apnea syndrome (OSAS) is not well studied among Indians. We sought to determine the prevalence and risk factors of OSA in a middle-aged urban Indian population. Methods: We conducted a two-stage, cross-sectional, community-based study in four different socioeconomic zones of the South Delhi district, India, from April 2005 to June 2007. In stage 1, subjects of either gender aged 30–65yrs were administered a questionnaire by door-to-door survey using systematic random sampling. Subjects that responded were classified as habitual and non-habitual snorers. In stage 2, all the habitual and 10% of randomly selected non-habitual snorers were invited for overnight polysomnographic study. Results: Of the 2860 subjects approached, 2505 (88%) completed stage 1. Habitual snoring was present in 452 (18%) subjects. In stage 2, OSA defined as apnea–hypopnea index ⩾5 was observed in 94 (32.4%) of 290 habitual snorers and 3 (4%) of 75 non-habitual snorers. Estimated population prevalence of OSA and OSAS was 9.3% (95% CI 8.2–10.5%) and 2.8% (2.1–3.4%) respectively. On multivariable analysis, male gender (adjusted odds ratio 3.8 [1.7–4.9]), body-mass index ⩾25kg/m2 (4.1 [2.0–8.3]), and abdominal obesity (2.2 [1.9–5.3]) were independently associated with the presence of OSA. A linear trend was observed in the prevalence of OSA across the socioeconomic strata. Conclusions: OSA is a significant public health problem in the middle-aged Indian population across the socioeconomic spectrum. OSA is associated with some of the well known risk factors for cardiovascular disease. [Copyright &y& Elsevier]
