Insights

Early dietary practices in Hong Kong children show lower energy intake and fat consumption compared to Western counterparts. Despite differences in growth metrics, dietary factors do not fully explain the smaller body build observed in Chinese children.

Area of Science:

  • Pediatric Nutrition
  • Growth and Development
  • Public Health

Background:

  • Understanding early childhood nutrition is crucial for optimal growth and development.
  • Previous studies suggest potential differences in growth patterns between Asian and Western children.

Purpose of the Study:

  • To investigate the relationship between early dietary habits and growth in Hong Kong children from birth to seven years.
  • To compare the growth and dietary intake of Hong Kong children with international references.

Main Methods:

  • Longitudinal study of 173 Hong Kong Chinese infants from birth to seven years.
  • Anthropometric measurements and dietary assessments (dietary history, 24-hour recall, food frequency) were employed.

Main Results:

  • Hong Kong children were lighter and shorter than NCHS and Australian references, with differences most pronounced between ages 1-5 years.
  • Energy intake decreased with age, and fat intake remained around 30%, with higher protein intake compared to Australian and Finnish children.
  • Calcium, iron, and vitamin C intake met at least 60% of US recommended daily allowances.

Conclusions:

  • Dietary differences do not fully account for the smaller body size of Chinese children compared to Caucasians.
  • The diet of Hong Kong children is becoming more Westernized, with increased consumption of animal products.

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
