A high level of morbidity among children with aggravating sociobiological factors (aggravating biological and obstetrical history, complicated newborn period, unhappy family) has been shown. The morbidity rates by cases and by days in different age groups are 1.3-2.8 times higher than those among episodically sick children. Children from unhappy families and those having a combination of 2-3 unfavourable factors in all age groups are to a greater extent suffering from chronic diseases mainly from bronchopulmonary and rhinopharyngeal diseases. Among them a small number of children (2.1-6.6%) have the I group of health. These children are in need of timely and differentiated medicopedagogical correction.
研究表明，具有加重社会生物学因素（生物学和产科病史加重、新生儿期复杂、家庭不幸）的儿童发病率很高。不同年龄组按病例和按天数计算的发病率比偶发性患病儿童高1.3至2.8倍。所有年龄组中来自不幸家庭以及有2至3种不利因素组合的儿童，在更大程度上患有慢性病，主要是支气管肺和鼻咽喉疾病。其中少数儿童（2.1%至6.6%）健康状况为第一组。这些儿童需要及时和有针对性的医学教育矫正。
