While health risks associated with air-pollution have been reasonably well-studied in developed countries, there is little evidence on health benefits achievable by HAP reduction through clean fuel use, especially in low- and middle-income countries (LMICs). Earlier the investigators showed that Liquid Petroleum Gas (LPG) for 24 months, reduced personal PM2.5 exposure by 58.17 percent which induced novel changes in immune and inflammatory responses in the participants; however cardiopulmonary markers remained relatively stable in post-intervention assessment.\n\nIn this study, the investigators aim to evaluate the effects of mobile phone based (mHealth) Behavioural Change Communication (BCC) intervention on adoption and exclusive use of LPG. The investigators also aimed to observe whether long-term effects of HAP reduction can impact the subclinical measures of cardio-vascular and pulmonary dysfunction and regulate innate and inflammatory immune function among women and children in semi-rural settings in Bangladesh. The investigators will also investigate the influence of exposure to HAP on antibody response to vaccines (adaptive immunity). The BCC intervention will be provided by conducting a large household level randomized controlled trial by educational intervention using mHealth based technology. In addition, the investigators will continue following the cohort and will conduct rigorous and repeated personalized (24 hours) and area (over 5 days) assessments of PM2.5 and black carbon (BC) exposure to examine the long-term effects of HAP reduction on subclinical measures of cardio-pulmonary and immune dysfunction including effect of HAP exposure on antibody response to vaccine.",[89,90,91,92],"Air Pollution","mHealth Intervention","Cardiopulmonary Function","Immune Function",[94,95,96,97,98],"Mobile based Behavioral Change Communication intervention","Household air pollution reduction","Cardiopulmonary function","Immune function","Clean fuel LPG","2024-03-20",{"date":101,"type":102},"2024-03-22","ACTUAL",{"date":104,"type":102},"2023-06-20",{"date":106,"type":83},"2027-06",{"name":5,"class":6},1]
