Parents often ask me, “Doctor, does my child need a health checkup?” My answer is “yes, it is necessary.” Why? Why? A person’s health needs to be managed from an early age. The concept of adult health management has been deeply rooted in people’s minds, and more and more adults are willing to invest time and money to have a health checkup once a year. Those with advanced concepts also take the initiative to seek one-on-one health management from medical professionals so as to modify their lifestyles, prevent and treat diseases, prevent serious adverse health problems, improve their quality of life and health well, and reduce health problems in old age. However, many parents are still entangled in whether their children should have medical checkups or not? Many parents think that there is no disease in their children, so why do they need medical checkups! Many parents also think that a trace element check is a medical checkup! These are all big mistakes! Children, especially those within 3 years of age, have rapid growth and development, strong plasticity, and are easily affected by external adverse environmental factors and poor parenting practices, resulting in growth and developmental deviations, and the early manifestations of many diseases are not obvious and are easily overlooked. If they are detected and corrected in time, they can often return to normal. Normal children can also grow better, be mentally healthier, realize their full potential, and become sick less often and go to the hospital less often under proper health management. Therefore, it is necessary to manage children’s health. The State provides basic health management services at community health centers in order to ensure basic child health needs. At the same time, families with the means are encouraged to choose more scientific and comprehensive health management for their children, covering “cognitive-behavioral-mental-physical health”. According to the current health management concept, the younger the child is, the more frequent the systematic management is, and it is recommended to have a physical examination once every three months for children within one year, once every six months for children aged 1-3 years, and once every year for children aged 3 years and above. After each physical examination, based on the results of the child’s physical examination, you should seek guidance from a medical professional (usually preferred to child health professionals) to make health recommendations, and parents can better promote the overall development of the child’s “mind, body and spirit” through parenting and monitoring. The Health Management Center of ZJU Children’s Hospital has developed a systematic medical checkup program for children of different ages, and even provides free health management advice for children after the checkup. So, how should parents choose the medical checkup program? Children with the following characteristics are recommended to come to the Health Screening Center for systematic management as early as possible: 1, children with backward growth and development; 2, children who often catch colds and get sick; 3, premature babies, children who have been hospitalized for more than 1 week with serious diseases at birth. The above children are recommended to undergo a comprehensive physical examination (unlike a simple physical examination in the community, and not just a check of trace elements!) ), and then consult with a doctor to develop a follow-up health management plan for regular monitoring. Children with good general health and good growth and development can have a yearly checkup, choosing to have it done at a well-qualified medical institution, and also needing to cover a growth and development assessment, and thereafter adjusting the cycle of checkups according to the situation. Children who come for medical checkups should preferably avoid acute periods of colds and sickness. Medical check-ups are mainly for the detection of problems and prevention of diseases, and treatment of diseases still needs to be carried out in specialized outpatient clinics to avoid delays in treatment.
