    Sampling
    Sampling Procedure


    Six HDSS sites collected data from the entire population aged 50 and over in their HDSS. Sampling in the two remaining HDSS sites (Navrongo, Ghana and Matlab, Bangladesh) was based on random selection of people aged 50 and over within the HDSS site.


    Response Rate


    A total of 58,004 respondents aged 50 years and over were invited to participate, and the response rate was 80%, resulting in a final total sample of 46,269, ranging from 2,072 in Nairobi to 12,395 in Purworejo. The response rate was: 63% in Agincourt HDSS, 103% in Ifakara HDSS, 77% in Nairobi HDSS, 92% in Navrongo HDSS, 100% in Filabavi HDSS, 81% in Matlab HDSS, 87% in Purworejo HDSS, and 68% in Vadu HDSS.


    Weighting


    All the analyses were weighted by the 2007 population age and sex distribution at each HDSS site to account for non-­-response. The descriptive results were standardised to the WHO world standard population distribution to account for the different population distributions across HDSS sites.
