PMID 29240655WHAT IT FOUND
Adults who received nurse-led contacts with goal choice, weekly action planning, neutral feedback, and a shared worksheet reported more moderate activity, more fruit and vegetables, and less fat after six sessions.
No control group.
Key findings
01Pretest-posttest differences on activity and diet measures were statistically significant, and estimated effect sizes were 0.53 for moderate aerobic activity, 0.82 for fruit/vegetable intake, and -0.57 for fat intake.
02Interveners reported delivering the study protocol adequately in 77-97% of contacts.
03Participants reported the information was useful, fit their situations, and had the right amount of detail, and they found weekly goals and obstacle planning helpful.

What it does not show
The study had no control group or random assignment, so behavior changes could be due to motivation, measurement, or attention from nurses. Only self-reported diet and activity were measured, not observed or physiologic outcomes. The sample was mostly White, female, and well-educated, and 52 participants were retained from 59 eligible people after 73 volunteers, so results may not apply to more diverse or less motivated patients. The study was designed to estimate effect sizes for future studies, not to prove effectiveness.
Declared interests
Authors reported no conflicts of interest. The article metadata lists non-U.S. government and NIH extramural research support.
The easy way to misread this
Do not conclude that nurse-led counseling alone caused better diet or activity. The intervention also included goal choice, action planning, neutral feedback, and a shared worksheet. The contribution of any single component cannot be separated, and there was no control group.
