It can be difficult for children and parents to make healthy food choices and get enough physical activity when they are exposed to environments that do not support healthy habits. Places such as child care centers, schools, or communities can affect diet and activity through the foods and drinks they offer and the opportunities for physical activity they provide. Other community factors that affect diet and physical activity include the affordability of healthy food options, peer and social supports, marketing and promotion, and policies that determine how a community is designed.
Neutrophils are cells that protect the body from infections. Low levels of neutrophils, called neutropenia, mean that the body cannot fight against bacterial infections, reports Healthline. Infections like tuberculosis, viral hepatitis, HIV and folic acid deficiency can affect the bone marrow, causing a reduced production of neutrophils. Autoimmune conditions, such as rheumatoid arthritis and lupus, can also use up or destroy neutrophils. A person can also be born with fewer neutrophils than normal, a condition called congenital agranulocytosis, explains Medical News Today.
