Outcome Measures

Primary Outcomes (5)

• Change in blood pressure from baseline to 6 and 12 months after a worksite health promotion intervention

  Blood pressure was measured manually by two research nurses using a sphygmomanometer and following protocols from the American Heart Association. Workers rested for about 5 minutes before the measurement, which was taken on their left arm while sitting.

  Baseline, 6 months, and 12 months

• Change in body mass index from baseline to 6 and 12 months after a worksite health promotion intervention

  Weight and height were measured in kg and cm, respectively, using a floor scale with stadiometer (Salter Brecknell brand). Workers were asked to remove their shoes and wore their usual clothing or uniform. Body mass index was calculated by dividing weight in kilograms by height in meters squared.

  Baseline, 6 months, and 12 months

• Change in oxygen uptake (VO2max) from baseline to 6 and 12 months after a worksite health promotion intervention

  The submaximum heart rate was obtained by applying Manero's protocol, which consisted on stepping up and down an ergometric bench. The frequency of each ascent was calculated as 90 for active workers and 84 for sedentary workers. One minute training was given to workers before the exercise to explain how to step up the bench (six steps to go up and six to come back down). The test lasted 5 minutes and was guided by an electronic metronome that marked the frequency of steps. A trained nurse measured each participant's heart rate by direct auscultation during the first 15 seconds immediately after the 5-minute exercise. This value was multiplied by 4 to obtain the sub-maximum heart rate and logged into a software that applied a correction factor by age and made group comparisons in Manero's nomograph, giving as a result the oxygen uptake in liters per minute.

  Baseline, 6 months, and 12 months

• Change in blood glucose levels from baseline to 6 and 12 months after a worksite health promotion intervention

  Levels of glucose were measured using a CardioChek® Plus analyzer (CCPA, PTS Diagnostics, model 2009). The materials used to take the test were alcohol swabs, sterile lancets, gloves, test strips, MEMo chip®, and the device CCPA.

  Baseline, 6 months, and 12 months

• Change in blood cholesterol levels from baseline to 6 and 12 months after a worksite health promotion intervention

  Levels of total cholesterol, LDL, and HDL were measured using a CardioChek® Plus analyzer (CCPA, People, Technology, and Service Diagnostics, model 2009). The materials used to take the test were alcohol swabs, sterile lancets, gloves, test strips, MEMo chip®, and the device CCPA.

  Baseline, 6 months, and 12 months

Study Arms (2)

Worksite health promotion program

EXPERIMENTAL

Participants had a baseline health risk assessment (HRA) after which they were invited to participate in a workplace health promotion program. The intervention lasted six months and included the following components: nutrition counseling, physical activity, and stress management. HRAs were performed 6 and 12 months after intervention onset.

Behavioral: Worksite health promotion program

Control

NO INTERVENTION

Participants only had a baseline and follow-up health risk assessments at 6 and 12 months.

Interventions

Worksite health promotion program BEHAVIORAL

Physical activity, nutrition, and stress management programs

Also known as: Wellness intervention

Worksite health promotion program
