Congratulations! Your BMI is in the healthy range. Maintaining a healthy weight decreases the risk of metabolic issues, heart strains, and vascular blockages.
Reference Table
WHO Body Mass Index (BMI) Reference Brackets
This table outlines the standard international classification thresholds established by the World Health Organization (WHO) and major scientific standardization bodies.
| BMI Bracket | Weight Classification | Health Risk Level | Imperial Equivalent |
|---|---|---|---|
| Below 18.5 | Underweight | Nutritional risk | Below 118 lbs (at 5'7") |
| 18.5 - 24.9 | Normal Weight | Minimal risk | 118 - 159 lbs (at 5'7") |
| 25.0 - 29.9 | Overweight | Increased risk | 160 - 191 lbs (at 5'7") |
| 30.0 and above | Obese | High health risk | 192+ lbs (at 5'7") |
Result Interpretation
What This Result Means Globally
- 1. Result ClassificationBody Mass Index Status: Your BMI value of 24.2 places you in the Normal weight range. This indicates a healthy ratio of weight to height, minimizing risks for cardiovascular issues.
- 2. Impact FactorsAlternative Cutoffs: If the WHO Asian Cutoff mode is enabled, the threshold for overweight falls from 25 to 23, and obesity from 30 to 27.5, which are more clinically accurate parameters for South and East Asian populations.
- 3. Target GuidelinesHealthy Weight Target: To remain in the healthy BMI bracket (18.5 to 24.9) at a height of 170 cm (5'7"), your weight should reside between 53.5 kg (118 lbs) and 72 kg (159 lbs).
FAQ Guide
Frequently Asked Questions
How is the body mass index calculated for a height of 170 cm and weight of 70 kg?
Body Mass Index (BMI) is calculated by dividing body weight in kilograms by height in meters squared. For a person who stands 170 cm (approx. 5 feet 7 inches) tall and weighs 70 kg (approx. 154 lbs), the BMI is exactly 24.2. This falls within the Normal weight bracket [Formula: BMI = kg / m^2 | Source: WHO Guidelines].
What are the health risks associated with a BMI in this bracket?
A BMI of 24.2 falls in the healthy weight range (18.5 to 24.9). This range is statistically associated with a low risk of developing weight-related chronic conditions like type 2 diabetes, coronary heart disease, and hypertension. Maintaining this weight profile is recommended for long-term health [Source: WHO Adult Health Guidelines].
How do Asian BMI cutoff thresholds differ from the standard WHO guidelines?
Standard WHO guidelines classify a BMI of 25.0 to 29.9 as overweight. However, studies show that Asian populations experience cardiovascular risks at lower BMI values. The Asian cutoff guidelines adjust the overweight threshold to 23.0 and the obesity threshold to 27.5 to reflect these demographic sensitivities [Source: WHO Asian Cutoff Standards].
What is the recommended weight range for a height of 170 cm?
For an adult standing 170 cm (5'7") tall, the recommended healthy weight range is between 53.5 kg and 72 kg (equivalent to 118 lbs to 159 lbs). Falling below this range classifies as underweight, while exceeding 72 kg represents overweight under standard WHO parameters [Source: NIH Clinical Guidelines].
Methodology
Formula Standard Used
Calculations adhere to international standard specifications:
* Note: Body Mass Index (BMI) is a proxy indicator of body fatness based on height and weight. It does not measure body fat directly and is applicable for adults aged 20 and older.
