Final answer:
Poor nutritional status can be influenced by poverty, lack of access to diverse diets, and certain diseases and conditions that reduce appetite or impair food digestion.
Step-by-step explanation:
Poor nutritional status can be influenced by several risk factors. One major risk factor is poverty, which can limit access to diverse diets with adequate sources of protein. Lack of food due to poverty or food deserts can also contribute to undernutrition. Additionally, certain diseases and conditions, such as cancer, inflammatory bowel syndrome, and psychiatric illnesses, can cause malnutrition by reducing appetite or impairing food digestion.
