Preventive healthcare, or prophylaxis, consists of measures taken for disease prevention. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes which begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.
A sedentary lifestyle is a type of lifestyle involving little or no physical activity, as opposed to an active lifestyle. A person living a sedentary lifestyle is often sitting or lying down while engaged in an activity like socializing, watching television, playing video games, reading or using a mobile phone/computer for much of the day. A sedentary lifestyle can potentially contribute to ill health and many preventable causes of death.
Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term overweight rather than obese is often used when discussing childhood obesity, especially in open discussion, as it is less stigmatizing. The prevalence of childhood obesity is known to differ by sex and gender.

As of 2020 Potti, who is employed at the Cancer Center of North Dakota, has had 11 of his research publications retracted, one publication has received an expression of concern, and two others have been corrected.
Screen time is the amount of time spent using a device with a screen such as a smartphone, computer, television, or video game console. The concept is under significant research with related concepts in digital media use and mental health. Studies show that screen time directly impact child development, and mental and physical health. The positive or negative health effects of screen time are influenced by levels and content of exposure. To prevent harmful exposure to screen time, some governments have placed regulations on its usage.
School meal programs in the United States provide school meals free of charge, or at a government-subsidized price, to U.S. students from low-income families. These free or subsidized meals have the potential to increase household food security, which can improve children's health and expand their educational opportunities. A study of a free school meal program in the United States found that providing free meals to elementary and middle school children in areas characterized by high food insecurity led to increased school discipline among the students.

Sophie Jamal is a Canadian endocrinologist and former osteoporosis researcher who was at the centre of a scientific misconduct case in the mid-to-late 2010s. Jamal published a high-profile paper suggesting that the heart medication nitroglycerin was a treatment for osteoporosis, and was later demonstrated to have misrepresented her results. She received a lifetime ban from receiving funding from the Canadian Institutes of Health Research and was named directly in their disclosure report, becoming the first person mentioned by name by the institute for scientific misconduct. Jamal was later stripped of her medical license for two years, regaining it in a controversial 3–2 decision.
