During childhood and pre-adolescence, the family environment is key to initiating and consolidating healthy styles in children through a balanced diet and basic hygiene habits. This study analyses hygiene, nutrition and health practices in Spanish families with children between 6 and 14 years of age according to the type of family (nuclear, single-parent or reconstituted) and the quantity, age and gender of the children. A representative Spanish national sample of 1103 Spanish parents, 270 fathers and 833 mothers, with children aged 6 to 14, is analysed. The study is descriptive, using statistical techniques with classic indicators (means, percentages). The results show that nuclear families manifest healthier habits, in general, and consider the consumption of pastries, ultra-processed food and excessive amounts of salt to be harmful. Furthermore, this family typology develops healthy and hygienic habits, such as brushing teeth daily, sleeping at least 8 h a day, drinking a glass of milk a day, eating fish more than once a week and eating fast food sporadically. They are also concerned about their children’s annual medical check-ups (paediatrician and dentist). It is concluded that the family type is related to the hygiene and feeding habits of the children.
