IFLS Photos

Physical Health Assessments: Photos from pilot tests of the collection of measures by the health worker.

A key feature of the IFLS data is the collection of physical health assessments. The first IFLS collected anthropometric measures (height and weight) from all individual respondents. In IFLS2, the set of health measures was expanded. Each household interviewing team was accompanied by a nurse who measured each respondent's height, weight, blood pressure, pulse, lung capacity, and hemoglobin level. Respondents were also timed as they rose from a sitting to standing position, which provides a measure of physical functioning. Below we show some photos taken during the pilot tests of IFLS2 and IFLS2+ for three of these physical health assessments.

Lung Capacity

We used a peak flow meter to measure the lung capacity of an individual in IFLS2 and IFLS2+. Lung capacity was assessed for all household members age 5 and above.


All household members had their height recorded. Children less than 2 years were measured for length lying down.

Hemoglobin Level

The IFLS 2 and IFLS2+ introduced a test of hemoglobin levels, assessed for all household members over the age of 1. The hemoglobin test assesses iron deficiency, which has been documented as an important nutrition problem in Indonesia. The test involves a small prick to the side of the fingertip. A microcuvette is then filled with a small blood sample automatically by capillary action. The microcuvette is then placed in the photometer; it takes between 14-45 seconds for the reading to appear.
