Association Between Physical Activity and Osteoarthritis of Knee with Quality of Life in Community-Dwelling Older Adults.

Older adults are relatively physically active compared to other age group. A lack of physical activity (PA) can cause chronic diseases including osteoarthritis of knee (OA knee) and might eventually reduce quality of life (QOL). This present study was aimed to investigate association between levels of PA and OA knee with levels of QOL in community-dwelling older adults.

Pesticides use and health impacts on farmers in Thailand, Vietnam, and Lao PDR: Protocol for a survey of knowledge, behaviours and blood acetyl cholinesterase concentrations.

Pesticides use in Southeast Asia has increased steadily, driven by the growth of large-scale commercial farming, as well as a desire to maximise food production in rural subsistence economies. Given that use of chemical pesticides, such as organophosphates and carbamates, has known potential health impacts, there are concerns about the safety of agricultural workers, and a need for a better evidence base to underpin regulation and worker education. This study, undertaken in 9 districts in Lao PDR, Thailand and Vietnam, will interview agricultural workers to investigate how they use pesticides, their knowledge of risks and self-protective practices, and their self-reported illness symptoms.

Statistical Analysis of Air Pollutants Concentration and Health Information Related to Respiratory Disease Patients in Bangkok, Thailand.

Air pollution can lead to exposure to foreign particles, air that can be inhaled deep into the lungs and cardiovascular system, causing diseases such as stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. The Pearson's product moment correlation coefficient (r) was used to determine the strength of association between a pair of variables, to test the relationship between these variables and to test whether the association is greater than could be expected by chance. The linear regression between respiratory disease patients, PM10, and other air pollutants were used in this study.

Numerical Analysis of Conventional Air Pollutants and PM10 Concentration Affected to Respiratory Disease Patients in Bangkok, Thailand.

Ambient air pollution is a major cause of death and disease globally. The linear regression between respiratory disease patients, PM10 and other criteria pollutants were used in this study. Among respiratory disease patients and CO was statistically significant with P-value of <0.
