PMID 28409170WHAT IT FOUND
Three 30-minute health-promotion education sessions based on Pender's model improved overweight and obese women's self-reported healthy eating over two months.
More women rated their nutrition favorable, but weight and BMI did not change.
Key findings
01The experimental group's mean nutritional behavior score improved after the three-session training.
02After training, 39 of 54 experimental-group women had favorable nutritional behavior, compared with 12 of 54 control-group women.
03The intervention did not change BMI or weight.

What it does not show
The nutrition outcomes were self-reported and were not observed directly. Follow-up was only two months, so longer-term eating habits and health outcomes were not shown. The inventories were developed by the researchers, not a standard published measure. The study included only women aged 18 to 60 with BMI 25 or higher, referred to hospital clinics in Hamadan, so results may not apply to men, people with other BMI levels, pregnant or breastfeeding women, or people with relevant medical conditions. The training was delivered as several components together, so it is not possible to know whether lectures, discussions, or the manual drove the change.
The easy way to misread this
Do not conclude that Pender-based training causes weight loss or improves health outcomes. The study measured self-reported nutrition behavior after two months and did not show a change in BMI or weight. It also gave lectures, questioning and answering, group discussions, and a manual together, so the effect of any single part cannot be separated.
