Malnutrition and Adapted Physical Activity in Older Adults: Impact of a Brief Training Program on General Practitioners’ Knowledge and Practices: A Randomized Controlled Trial
This randomized controlled trial demonstrates that a brief, targeted training intervention consisting of a 15-minute video and a leaflet significantly improved general practitioners' knowledge and positively influenced their prescribing practices regarding adapted physical activity and malnutrition in older adults.

As people live longer, the challenge of staying healthy in later years shifts from simply surviving illness to maintaining independence. Two silent forces often undermine this independence: the slow loss of muscle and strength known as frailty, and the gradual decline in nutrition called malnutrition. In France, where the population is aging, doctors are on the front lines of this battle. They are the ones who can spot these problems early and offer solutions that do not involve pills. One powerful tool is adapted physical activity, which means exercise tailored specifically to an older person's abilities, designed to improve balance and strength without causing injury. Another is dietary management, which involves not just prescribing nutritional supplements, but teaching patients how to enrich their everyday meals with more protein and calories. While these approaches are known to work, many family doctors feel unprepared to use them, often citing a lack of training as the main reason they do not prescribe these non-drug treatments.
To see if a quick, focused lesson could change this, researchers in the Pays de la Loire region of France conducted a study with general practitioners. They recruited doctors who were either finishing their training or already practicing, and randomly divided them into two groups. One group received a brief training program focused entirely on malnutrition, while the other group received a similar program focused entirely on adapted physical activity. Each training session was short, consisting of a video lasting between ten and fourteen minutes followed by a summary leaflet. The videos were designed to cover the basics: what the conditions are, how to recognize them, and how to manage them in a regular clinic. The doctors were then asked to fill out a questionnaire about their habits before the training and again one month later. This setup allowed the researchers to see if a small investment of time could lead to real changes in how doctors care for their older patients.
The results showed that even this brief intervention made a measurable difference. Doctors who watched the video on physical activity began prescribing adapted exercise significantly more often than those who did not. Before the training, these doctors prescribed such exercises about once a month on average; afterward, that number rose to roughly three and a half times a month. The training also helped them remember where to send patients for help, as their knowledge of local resources for physical activity improved noticeably. On the other side of the study, doctors who received the malnutrition training changed how they approached diet. They did not start prescribing more oral nutritional supplements, as those were already being used frequently. Instead, they shifted their focus toward dietary enrichment, which involves adding healthy, nutrient-dense foods to a patient's regular meals. The proportion of malnutrition cases where doctors recommended this kind of food-based strategy jumped from about thirty-eight percent to nearly seventy percent.
However, the study also revealed the limits of a short training session. While the doctors changed what they prescribed, the total number of conversations they had about these topics did not increase significantly. The training did not lead to a surge in referrals to dietitians or dentists, nor did it drastically alter how often doctors diagnosed these conditions in the first place. The researchers noted that the doctors who participated might have been more interested in these topics to begin with, and the follow-up period was too short to know if these new habits would last for years. Despite these boundaries, the findings suggest that a simple, targeted educational tool can break through the barrier of insufficient training. By giving doctors a clear, concise guide and a reminder of local resources, it is possible to nudge their daily practice toward better, non-drug care for the aging population.
