Level of physical activity among adolescents in Ernakulam District, Kerala: A cross-sectional study.

Introduction: For children aged 5-17 years, WHO recommends moderate-to-vigorous intensity physical activity for at least 60 minutes daily which would account for 420 minutes of physical activity per week regardless of working days or holidays. With the increasing prevalence of non-communicable diseases in Kerala, this study aimed to assess the level of physical activity among high school students in Ernakulam District, Kerala. Materials and Methods: A school-based cross-sectional study was conducted among ninth and tenth standard students of two randomly selected schools in Ernakulam District. A total of 303 children were recruited for the study. Consent rate and response rate of the study were 100%. A structured questionnaire adapted from MRC-CPAQ (Children's Physical Activity Questionnaire) was used to collect the data. Results: The study revealed that out of 303 students, 72.9% were < 15 years, 77% were males, and 59% were urban residents. More than 70% of the participants were actively involved in physical activity of moderate-to-vigorous intensity. Males, in the age group of 15 years and above, having a separate play area, and those with no siblings were found to have significantly higher levels of physical activity. Conclusion: The study was able to identify a positive trend for physical activity among adolescents. Town planning and building of play areas are essential to develop and retain the habit of physical activity among adolescents.

Knowledge, attitude, and practice regarding mosquito-borne diseases among migrant laborers from a migrant settlement in Ponekkara, Ernakulam Kerala.

Background: Mosquito-borne diseases (MBDs) such as Malaria, Dengue, Chikungunya, lymphatic filariasis, and Japanese Encephalitis are important public health problems in India. Ernakulam in Kerala being a hub of construction activities has a large influx of migrants from Odisha, West Bengal, Bihar, Assam, U. P., Jharkhand, T. N., and Karnataka. Hence, the objective of this study was to assess the knowledge, attitude, and practice related to MBDs and the associated factors among the migrant laborers from a migrant settlement in Ponekkara, Ernakulam Kerala. Materials and Methods: A cross-sectional study was done among 179 migrant laborers from a migrant settlement in Ponekkara, Kerala, from September 2021 to November 2021 using a pretested semi-structured questionnaire to collect information regarding socio-demographic details and their knowledge, attitude, and practice regarding mosquito borne diseases. After taking verbal consent, the questionnaire was administered by the investigator. Descriptive and univariate analysis was done using SPSS Version 20. Results: It was found that 58.4% of the migrant laborers had poor knowledge, 55.9% had poor attitude, and 61.5% of them had poor practice regarding MBDs. On univariate analysis, a statistically significant association was observed between attitude score and the level of education. Conclusion: The findings showed that migrant laborers had an overall poor knowledge, attitude, and practices regarding MBDs. Consequently, there is a need to plan an awareness program among the migrant settlements regarding MBDs.

Seroprevalence of COVID-19 antibody among children aged 5-17 years in an urban and rural area of Ernakulam District, Kerala.

Background: The age group of 5-17 years belongs to the vulnerable segment of the population for COVID-19 infection in India. Seroprevalence in this population can therefore allow inferences to be made about the extent of infection. Objectives: The objective of this study was to assess the seroprevalence and to determine the factors associated with COVID-19 antibody among children aged 5-17 years in an urban and rural area of Kochi, Kerala. Methods: A community-based cross-sectional study was undertaken in the urban and rural field practice areas of the community medicine department in a medical college, Kochi. A semi-structured questionnaire was used to collect information about sociodemographic data, history related to COVID-19, and the severe acute respiratory syndrome coronavirus 2 antibody test result. Blood samples were collected and tested for the presence of COVID-19 antibodies using the Wantai test kit after attaining informed assent from the parent/guardian. Results: The seroprevalence of the COVID-19 antibody was 48.3% among participants. The seroprevalence of COVID-19 antibody was higher among children of mothers with skilled/unskilled occupation, residents of rural area, above poverty line category, those with a history of COVID-19, and those who had a history of contact with COVID-19-positive patients. Conclusion: Half of the study population were COVID antibody positive, and the rest were at risk of infection. Therefore, adherence to COVID-19 guidelines is essential to control further spread of infection among children.

Investigating a community wide outbreak of hepatitis A in Kerala, India.

BACKGROUND: There was an outbreak of acute hepatitis in Nellikuzhy panchayat of Kothamangalam taluk, Ernakulam district, Kerala, during November and early December 2016. Objective of this study is to describe the epidemiological features of the outbreak and to identify the probable source. MATERIALS AND METHODS: The outbreak was defined in terms of time, place, and person. A hypothesis was generated and tested using a case-control study. Cases were selected by simple random sampling from the line list and controls were age-matched neighborhood individuals without any history of jaundice. Chi-square test, univariate analysis, and multi-variate logistic regression analyses were done to identify the probable risk factors. RESULTS: Around 223 hepatitis A cases were identified. Attack rate was found to be highest among the age group of 16-30 years at 1.44% and was eight times higher among males. Epidemic curve suggested a point source outbreak possibly from exposure to food or water from a newly opened hotel in the area. The case-control study confirmed the hypothesis with a statistically significant association between cases and history of exposure to food from the hotel [OR 120; 95% CI 14.6-996.2; P value < 0.001]. CONCLUSION: Observations and results of the case-control study revealed that the probable source of the Hepatitis A outbreak at Nellikuzhy panchayat was a hotel. The study findings also add evidences to the changing epidemiological pattern of hepatitis A in Kerala, and warrant the necessity to enforce food safety rules in the State.
