Abstract
Background
Children left behind (CLB) are those, who have been left behind at their original residence while one or both parents migrate to other places for work. The aim of this study was to systematically review studies where the physical health consequences for CLB were analysed.
Methods
We searched the Web of Science, PubMed, Academic Search Complete, PsycINFO and Cochrane databases. We included studies reporting physical health outcomes of children affected by parent migration.
Results
We selected 35 studies from a total of 2191. The results reveal that, overall, the absence of one or both parents is related to poorer child health - the nutrition of CLB is not healthy or balanced and is insufficient, leading to higher rates of anaemia and poor growth indicators of affected children. Boys left by parents are smaller than boys who were never left behind. CLB face lower underweight or stunted growth risks due to the additional income from remittances which ensures sufficient food for the household, this can also lead, however, to overweight and obesity. Unhealthy lifestyle behaviours such as smoking, alcohol, food preferences, lower physical activity and higher risk of injuries were more prevalent among CLB. CLB were more likely not to have completed the recommended vaccination programme than those living with their parents. Opinions vary on how emigration of parents affects children’s well-being and quality of life. CLB had higher probabilities of higher well-being than children living in non-migrant households. However, health-related quality of life (HRQoL) of CLB scored significantly lower than HRQoL of non-left-behind children.
Conclusions
The migration of parents has negative impacts on the child’s physical health, however it can also have positive impacts on children’s well-being when basic needs for sufficient nutrition are not satisfied in the home countries. Public health interventions should be taken to ensure the health of the CLB population.
