This paper summarizes the arguments and counterarguments within the scientific discussion on the factors that influence public health service. The main purpose of this research is to determine the expected indicators of pathogenic and sanogenic effects on significant risk factors of pathology among children. For achieving the research goal, the authors substantiated the models of final results for the modification of risk factors. Investigation of antenatal and genealogical factors in healthy and ill children groups was performed using a specially compiled expert assessment card and parents’ interviews. The systemic population modeling methods were applied to develop and substantiate population health management models (early diagnosis and primary prevention). Evaluation of the expected effectiveness of the N-factor program of primary prevention was carried out on a set of genealogical and antenatal factors. Conducted logical analysis of the methodology of quantitative and qualitative determination of health and the gathered experience in that respect were taken into account in developing population models of preventive effects. This study provides the identified priority directions for realizing the regional and population programs to implement them further. The authors presented the example of calculating the expected effectiveness of children’s health management by eliminating the investigated factors. The authors determine the priority directions for realizing the regional and population programs pathology based on the influence on the various elements to improve the public health services system. An example of calculating the expected effectiveness of children’s health management by eliminating these factors is given. The obtained results could be used to further research the issues associated with a prospective assessment of the program’s effectiveness in reducing the impact of antenatal and genealogical factors on children’s health.

The author’s legal support of the components of the structural-functional model (SFM) of medical care for children with bronchopulmonary dysplasia (BPD) is given in this article, in particular regarding social support for families in which children with disabilities are raised, which is aimed at strengthening social protection, individualization of the worker schedule and employment, expanding the availability and cheapening of food products, patient-oriented social assistance and improving the economic condition of persons with children with disabilities, other urgent problems of patients with BPD. The Law of Ukraine number 544-VIII «On Employment» renewed the rights of citizens with additional guarantees in employment, and provided these guarantees, and with respect to the target contingent of the SFM, it strengthens the social protection of parents, the establishment of a shorter working time or part-time or non-working week only for women who raise a disabled child, individualization of working time in the care of a sick family member. It is envisaged to ensure fairness in taxation in accordance with EU Council Directive number 2006/112, and in relation to the target contingent of the SFM — the reduction in the cost of food for special nutrition for children. It is also ensured that social justice is implemented in the pension provision of the parental family and, in relation to the target contingent of the SFM, is the improvement of the economic condition of persons with disabled children. A comprehensive reform of the health care system has been defined to create a network of state and communal institutions with a sufficient level of independence, which in relation to the target contingent, the SFM implements approaches aimed at creating a patient-oriented system that can provide medical care in an institution. In order to improve the legislative and regulatory support during 2014–2019, directions for the implementation of the legislative initiative were identified. Socio-medical assistance has been improved: social protection of parents with dependent children under 6 years of age has been strengthened, working hours have been individualized when taking care of a sick family member, food products have been cheapened for special nutrition of children, the creation of a patient-oriented care system has been substantiated, the economic state of persons supporting children has been improved while increasing the mutual responsibility of parents in material assistance and other, which improved the regulatory and legal support of this component of the SFM of medical care for children with BDL.
