Summary
Family stress impacts preschool girls' sugar intake, with higher family dysfunction linked to lower sugar consumption. This association was not observed in boys, suggesting sex-specific effects.
Area of Science:
- Pediatric Nutrition
- Family Health Studies
- Child Psychology
Background:
- Family stress is a significant environmental factor influencing child health behaviors.
- Understanding the relationship between family stress and dietary habits is crucial for early intervention.
- Previous research has not fully explored sex-specific associations between family stress and sugar intake in preschoolers.
Purpose of the Study:
- To investigate the association between family stress (household chaos, family dysfunction) and sugar intake (total, free, added) in preschool-aged children.
- To determine if this association differs between boys and girls.
- To provide insights into sex-differentiated nutritional patterns within families experiencing stress.
Main Methods:
- Utilized data from 210 families and 267 children (mean age 3.6 years) from the Guelph Family Health Study.
- Assessed family stress using validated measures of household chaos and family dysfunction.
- Quantified sugar intake via an Automated Self-Administered 24-hour Dietary Assessment Tool and analyzed associations using linear regression models with generalized estimating equations.
Main Results:
- An inverse association was found between family dysfunction and girls' intake of total, free, and added sugars (controlling for covariates).
- Specifically, higher family dysfunction correlated with lower sugar consumption in girls (e.g., total sugars: β = -3.8, P = 0.03).
- No significant associations between family stress measures and sugar intake were observed in boys.
Conclusions:
- The findings suggest that the relationship between family stress and sugar intake is sex-dependent in preschool children.
- Family dysfunction may play a protective role against high sugar intake in girls, warranting further investigation.
- These results highlight the importance of considering child sex when examining family environmental influences on pediatric dietary behaviors.

40.0K
Like many living organisms, plants have tissues that specialize in specific plant functions. For example, shoots are well adapted to rapid growth, while roots are structured to acquire resources efficiently. However, sugar production is primarily restricted to the photosynthetic cells that reside in the leaves of angiosperm plants. Sugar and other resources are transported from photosynthetic tissues to other specialized tissues by a process called translocation.

Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key...

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.

Family therapy conceptualizes psychological challenges as arising from dysfunctional interactions within the family unit, rather than as isolated issues within individuals. This approach seeks to address and transform the patterns of communication, roles, and relationships within families to promote healthier dynamics and emotional well-being for all members.
