The program was implemented at an African-American church in Nashville, Tennessee.</p><p><strong>Results: </strong>Thirty-four participants (aged 56.1 ± 11 years, body mass index (BMI) 36.7 ± 6.6 kg/m<sup>2</sup>) completed the intervention. Lifestyle changes after the 12 weekly sessions showed some positive trends including reduced sodium intake (from 2725.3 ± 326.5 to 2132 ± 330, mg/day, P = 0.008), increased walking steps (from 4392.1 ± 497.2 to 4895.3 ± 497.9, steps/day, not significant), and slightly decreased Perceived Stress Scale (PSS) scores (from 13.7 ± 1.4 to 12.4 ± 1.5, not significant).
