Lack of physical education is the inadequacy of the provision and effectiveness of exercise and physical activity within modern education.

Models that describe health behavior change can be distinguished in terms of the assumption whether they are continuum-based or stage-based. [7] A continuum (mediator) model claims that change is a continuous process that leads from lack of motivation via action readiness either to successful change or final disengagement.
Well-nourished women are less likely to experience risks of birth and are more likely to deliver children who will develop well physically and mentally. [2] Maternal undernutrition increases the chances of low-birth weight, which can increase the risk of infections and asphyxia in fetuses, increasing the probability of neonatal deaths. [ 128 ]
