ABSTRACT
Background: Falls are an important cause of morbidity and mortality in elderly people. Falls lead to multiple medical and psychological problems in the elderly. Aim was to study the prevalence of falls among the elderly and to find the associated risk factors for falls among the elderly living in an urban slum in Chennai.Methods: A cross sectional study was conducted among elderly population over 60 years and above, in an urban slum area. About 150 elderly were selected using simple random sampling method, using the voters list as the sampling frame. A pretested questionnaire was administered to collect information about falls. In statistical analysis univariate and multivariate logistic regression was employed using SPSS version 22.Results: Of the 150 elderly persons studied, prevalence of falls rate is 35.3% (95% CI 28.13 to 43.26). Of them 64.1% had one episode of fall and 35.8% had recurrent falls. The prevalence of fall among persons with comorbidities like hypertension or diabetes was 39.3% and 36.1% respectively .The rate of fall among those using a walking stick was 58.3%, having tremors was 15% and having abnormal gait was 40%. The risk factors found to be significantly associated in univariate analysis were gender and presence of tremors (p<0.05). In multivariate analysis none of the factors showed statistical significance.Conclusions: Falls are very common among elderly. It is utmost important to prevent the falls by making necessary environmental modifications and following healthy lifestyle.
ABSTRACT
Background: Having a healthy behavior and physiology is impossible without normal sleep pattern. Between the ages 18 and 25, people are prone to sleep disturbances. College life, which mostly occurs during this ages also affects the sleep pattern.Methods: This is a descriptive cross sectional study conducted among MBBS students of Stanley Medical College during august to September 2009. About 300 students were randomly selected using table of random numbers. Data was collected using a questionnaire and entered in SPSS version 16 software. Analysis was done using chi-square test. P value of less than 0.05 was taken as statistically significant.Results: Prevalence of insomnia is found to be 37% and is significantly higher among males. Disturbed sleep is higher among males.Conclusions: Prevalence of insomnia is 37% and is significantly higher among males. About 26.3% of the participants had disturbed sleep
ABSTRACT
The distribution and abundance of fish eggs and larvae have been studied at two Stations of Arasalar estuary. Eggs of Stolephorus sp., Mugil cephalus, Sardinella sp., Cynoglossus sp and the larvae of Stolephorus indicus, Ambassis commersoni, Terapon jarbua, Chanos chanos, Trichiurus sp Anguilla sp and Thryssa sp have been collected and identified. Environmental parameters such as temperature, salinity, pH and dissolved oxygen were also recorded. The present study clearly indicate the higher occurrence and abundant of fish eggs and larvae during March - July. The fair numbers of eggs and larvae indicate the existence of breeding ground within the estuary. Study on the physico-chemical parameters found that the abundance and distribution of fish eggs and larvae were influenced by the salinity of this estuary.
