In Person: Anthropometric Measures and Functioning
KANTHRO Anthropometric and Functioning Measures OVERVIEW The 2011 in-person interview included five anthropometric measures: height; weight; waist circumference; hip circumference; and two photographs; and four functioning measures: lung strength; timed chair rise; grip strength; and walking speed. To maintain consistency across participants interviewers had identical equipment for the measures. For the height measure participants were asked to remove their shoes and stand straight with his or her back to a wall. Interviewers gently placed a triangle on the participant's head and marked a post-it note where the base of the triangle met the wall. Interviewers used a retractable measuring tape to measure the distance between the floor and the pencil mark on the post-it note. For the weight measure participants were asked to remove their shoes and any objects form their pockets temporarily. The scale was placed on a hard surface, if such a surface could not be found then the participant was asked to self-report weight. Waist and Hip circumferences were taken over the participant's clothing. Participants were however asked to remove anything bulky such as a sweater. For women, waist circumference was measured twice, once at the naval and once at the narrowest part of the waist. For men the waist circumference was taken at the level of the navel, or belly button. The hip circumference is measured at the maximum circumference of the hips. Maximum circumference of the hips is the widest circumference point between the waist and the knees. Lung strength was measured three times using a peak flow meter. Whenever possible the measurement was taken from a standing position. Participants were instructed to take as deep a breath as possible; place mouth around the mouthpiece, make sure tongue is away from the mouth piece, to not obstruct the peak-hold needle on the meter, and to blow out all the air in the lungs at once in a blast of air. Participants rested for a minimum of 30 seconds between peak flow measures. Grip strength was measured with a dynamometer twice using the dominant hand. Dynamometers were calibrated throughout the fielding period to maintain comparability. The measures were taken with the participant in the sitting position with the arm at a 90-degree angle, with elbow down along the body. Participants were instructed to squeeze as hard as they could for one second. The chair rise measure timed how long it took the participant to rise from the chair into a standing position five times without using their arms. Participants crossed their arms at their chest. The timer began in the sitting position and stopped when the participant was standing after the fifth rise. Interviewers also recorded the height of the chair at the front of the seat, directly in the middle. The walking speed course was 2.5 meters and two measures were taken. Interviewers requested that participants wear sturdy shoes and to walk at their normal pace. The timer began when the interviewer instructs the participant to "begin" and ends when his or her heel fully crosses the finish line. The only measure for participants who were living in a nursing home was the photograph.
