An information, education and communication module to reduce dietary salt intake and blood pressure among tea garden workers of Assam

Objective High salt diet increases blood pressure. Tea garden workers (TGW) of Assam, India have high (60.8%) prevalence of hypertension (HTN), which may be due to consumption of extra salt (salt as side dish) and salted tea at work place and home. The present study evaluated an information, education and communication (IEC) module to reduce salt intake and blood pressure among TGW. Methods Two tea gardens (usual care and intervention) were selected at random covering a total population of 13,458. The IEC module consisting of poster display, leaflets, health rally, documentary show, individual and group discussion was introduced in the intervention garden targeting study participants, health care providers, key stake holders, school children and teachers. IEC intervention was continued for one year. Participants from usual care and intervention were followed at three monthly intervals and BP and other information were compared after one year. Results A total of 393 study participants (Non intervention: 194; intervention: 199) were included. After one year of follow up, consumption of extra salt was reduced significantly in the intervention participants (66.3 vs. 45.5%, p = 0.000). Intention to treat analysis revealed significant reduction in systolic [−6.4 (−8.6 to −4.2)] and diastolic [−6.9 (−8.1 to −5.7)] blood pressure after one year. Prevalence of HTN was reduced significantly (52.5 vs. 40.0%, p = 0.02) among them. Conclusions Our IEC module created awareness about risk of hypertension associated with high salt intake and could reduce dietary salt intake and BP.
