Insights

Over 25 years, maternal height and pre-pregnancy weight increased in healthy Croatian women. Higher maternal body mass index (BMI) correlated with heavier newborns, influenced by age and lifestyle.

Area of Science:

  • Anthropology
  • Public Health
  • Maternal Health

Background:

  • Secular trends in maternal and newborn anthropometric factors are crucial for understanding population health.
  • Previous studies indicate shifts in women's health parameters over time.
  • Investigating generational changes in Croatia provides specific regional insights.

Purpose of the Study:

  • To analyze secular trends in anthropological factors among women and their newborns over two generations.
  • To identify changes in maternal height, pre-pregnancy weight, and body mass index (BMI).
  • To explore associations between maternal characteristics and newborn birth weight.

Main Methods:

  • A 25-year longitudinal survey of 2414 healthy women and their newborns at a University Hospital Center in Zagreb, Croatia.
  • Data collection included pre-pregnancy weight, BMI, height, age, residence, education, parity, and newborn weight.
  • Randomized sampling included women from urban and rural environments with varying educational backgrounds and parity.

Main Results:

  • Maternal height increased by 3.1 cm over 25 years, positively correlating with higher education.
  • Pre-pregnancy weight increased by 2.8 kg, associated with older age, higher parity, and rural residence.
  • Maternal body mass index (BMI) showed significant variations with birth order, age, and living environment, and was linked to heavier newborns.

Conclusions:

  • Significant generational changes in maternal anthropometric indicators were observed in the Croatian population.
  • Factors like education, age, parity, and living environment play a role in maternal weight and BMI trends.
  • Higher maternal BMI is a predictor of increased newborn birth weight.

Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
Nature and Nurture01:10

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...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
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,...
