成年身高计算器：科学预测您孩子的生长轨迹

Height prediction, or future height estimation, involves scientifically estimating a child's eventual adult stature. While genetics, particularly parental heights, are primary determinants (accounting for 60-80% of height), factors like nutrition, overall health, and environmental conditions also significantly influence a child's growth journey.

This calculator employs common methodologies like the Mid-Parental Height (MPH) formula (also known as the Tanner method) to provide a reliable estimate. It's crucial to understand that these are scientifically-backed estimations, but individual growth patterns can vary, leading to differences from the predicted adult height.

Our Height Calculator primarily uses the widely recognized Mid-Parental Height (MPH) method. This approach is a common way to estimate genetic height potential.

Understanding the Mid-Parental Height (MPH) Formula:

The MPH method calculates a child's target adult height based on the biological parents' average height, with a standard adjustment for gender. The typical adjustment is adding 6.5 cm (or 2.5 inches) for boys and subtracting 6.5 cm (or 2.5 inches) for girls from the mid-parental height.

While the first calculator section allows input of the child's current age, height, and weight for comprehensive record-keeping, this calculator's core prediction relies on the MPH formula using parental heights. More advanced growth prediction models, which might incorporate current child data with growth charts, are not part of this specific tool but represent another area of pediatric growth assessment.

Follow these simple steps to use our height calculators and get an estimation of future adult height:

For the 'Child & Parents' Data' Height Calculator:

1. Select your preferred unit system (Metric or Imperial).
2. Enter the child's age in years and select their gender.
3. Optionally, enter the child's current height and weight.
4. Enter the biological mother's height and the biological father's height. Click 'Calculate'.

For the 'Parents' Heights Only' Predictor:

1. Select your preferred unit system.
2. Enter the biological mother's height and the biological father's height.
3. Click 'Calculate'. Results for both a boy and a girl will be shown.

While genetics form the primary blueprint for a child's height, a combination of other crucial factors significantly contributes to their final adult stature. Understanding these can provide a more holistic view of child growth:

• Genetic Predisposition (Parental Height): Approximately 60-80% of an individual's height is determined by genes inherited from their biological parents. This is why the Mid-Parental Height formula is a foundational tool for prediction.
• Nutrition and Diet: A balanced diet rich in essential vitamins (like Vitamin D), minerals (especially calcium and zinc), and proteins is fundamental for optimal bone growth and development throughout childhood and adolescence.
• Hormonal Balance: Key hormones, including Growth Hormone (GH), Thyroid hormones, and sex hormones (estrogen and testosterone), play pivotal roles in regulating growth spurts and final height attainment.
• Overall Health & Medical Conditions: Chronic illnesses, certain medical conditions (e.g., celiac disease, Turner syndrome), or prolonged use of some medications can impact a child's growth trajectory and potentially affect their adult height.
• Environmental and Lifestyle Factors: Adequate sleep (as growth hormone is primarily released during sleep), regular physical activity, and a generally healthy lifestyle contribute positively to a child reaching their full genetic height potential. Exposure to certain environmental toxins can also be a factor.
