Data on bio-impedance and hand-grip were collected in several studies in Karonga and Lilongwe, and these data are combined into one dataset using the do-file bioimp_handgrip_combine.do
The variables available are slightly different for each study so each dataset are harmonised before being appended together.
An attempt is made to have at least one set of fat mass (kg & %) and fat-free mass (kg &%) variables for each record: in some studies one or all of these were produced by the bioimpendace machine and recorded, in others the impedance value from the machine was recorde, in others the impedance value was not recorded but the resistance value was. To account for all these differences 3 different versions of the body mass variable are given:
*_M values directly from the machine, or derived from machine values
*_I values calculated using the weight/height and the impedance value
*_R values calculated using the weight/height and the resistance value
Data on bio-impedance and hand-grip were collected in the following studies:
ARK African Research into Kidney Disease Study
GAP Study of growth and stunting in adolescents
KDU Kidney disease of unknown origin study
NUT Development of nutritional strategies for diabetes prevention in Malawian adults at high diabetes risks
PHD Pre-hypertension, pre-diabetes study
In the variable labels (S) indicates that the variable is unchanged from the original source and (D) indicates that it is a 'derived' variable, often using more than one source variable. For both types information on where the data come from and how they are processed is found in the 'Recoding and Derivation' section
