Data for: "Study on Health seeking behaviour and determinants of undiagnosed hypertension in poor households in the Philippines, part of the RESPOND study (SHARP-RESPOND)" – Data Codebook

Persistent identifier

10.17037/DATA.00004658

Description

The SHARP-RESPOND study aimed to describe the characteristics and health-seeking behaviours of individuals with undiagnosed hypertension in low-income households in the Philippines and identify the factors influencing undiagnosed hypertension. The analysis is based on observations from 516 people with hypertension from low-income households in the Philippines as part of the RESPOND study. A survey collected the characteristics of participants with undiagnosed hypertension, which were compared to those with diagnosed hypertension to identify determinants of undiagnosed cases. A follow-up survey one year later gathered data on whether undiagnosed participants had subsequently received a formal diagnosis.

Data access conditions
