Singapore Population Health Studies (SPHS)

The Singapore Population Health Studies (SPHS) is a population-based health research initiative at the Saw Swee Hock School of Public Health, National University of Singapore. SPHS aims to investigate the interactions between lifestyle, physiological, genetic and other omics biomarkers and their impact on health and longevity. In addition, SPHS will serve as a platform to monitor risk factors in the population and gain insight into determinants of health-related behaviours. For this purpose, SPHS includes over 50,000 adult Singaporeans and permanent residents from three major ethnic groups (Chinese, Malay, and Indian), for a better understanding of disease etiology in urban Asian settings, and the development of improved preventive and therapeutic measures for Singapore and other Asian populations.

Over twenty years, SPHS has built up several cohort studies, including multiple phases of the Multi-Ethnic Cohort (MEC1, MEC2 and MEC3), Diabetic Cohort (DC), Singapore Health Studies (SH2012 and SH2), and Community Healthy Study (CHS).

For each cohort with multiple timepoints of follow-up, we denote the specific timepoint as follows: CohortNameAbbreviation_Tj denotes jth timepoint, for example, MEC1_T1 refers to the first timepoint (baseline) of MEC1.

A tabulation of the variables collected across all studies and timepoints, grouped into sections and subsections, can be downloaded here. A screenshot of the mapping file is shown below.


The cohort names, abbreviations and their period of baseline collection are as follows:

 Cohort Name  Abbreviation  Baseline collection
 Multi-Ethnic Cohort Phase 1  MEC1  2004 – 2010
 Multi-Ethnic Cohort Phase 2  MEC2  2013 – 2015
 Multi-Ethnic Cohort Phase 3  MEC3  2019 – ongoing
 Diabetic Cohort  DC  2004 – 2010
 Singapore Health Study 2012  SH2012  2012 – 2014
 Singapore Health Study 2  SH2  2014 – 2015
 Community Health Study  CHS  2015 – 2016

The maximal sample size described here are based on a data freeze derived on November 2021. For data requests, the eventual sample size will differ based on consent.
