This study assessed the effectiveness of a worksite wellness program. A within-group study design was conducted. Assessment was based on 3737 continuously employed workers at a large agribusiness during 2007–2009. More than 80% of employees participated in the program, with a higher percentage of women participating. Clinically significant improvements occurred in those who were underweight, those with high systolic or diastolic blood pressure, high total cholesterol, high low-density lipoprotein, low high-density lipoprotein, high triglycerides, and high glucose. Among obese employee participants, significant improvements occurred in selected mental health and dietary variables. Among those who lowered their BMI, significant decrease occurred in fat intake, and significant increase resulted in weekly aerobic exercise and feelings of calmness and peace, happiness, ability to cope with stress, and more physical energy.
