Study of the cardio respiratory response to six minute walk test in normal weight, overweight and obese children aged 7 to 10 years

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Normal weight, overweight, and obese children (n=120). Intervention: Overweight and obesity (higher BMI grades) vs. Normal weight children. Primary outcome: Distance walked in six-minute walk test (meters) (MD 27.05, p=0.0001).

Q: What does this research mean for the field?

Obese and overweight children walk a significantly shorter distance and exhibit a higher systolic blood pressure response during the six-minute walk test compared to normal-weight peers. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key result

Childhood obesity is linked to ~27-meter shorter 6-minute walk distance versus normal weight peers.

MD −27.05
P=0.0001
n=120

Why the study?

The cardio respiratory response to six minute walk test in normal weight, overweight, and obese children aged 7 to 10 years was not well studied.

Does overweight and obesity alter the cardiorespiratory response and distance walked during a six-minute walk test compared to normal weight in children aged 7 to 10 years?

Key Points

To examine cardiorespiratory responses and exercise performance during a six-minute walk test across normal weight, overweight, and obese children aged 7 to 10 years.
Assessed physiological responses pre- and post-six-minute walk test (6MWT), including systolic and diastolic blood pressure, respiratory rate, heart rate, distance walked, and rate of perceived exertion (RPE).
Compared hemodynamic and exercise variables across groups using ANOVA and Bonferroni multiple comparison post-hoc tests.
Normal weight children walked significantly farther (500.12±25.63 m) than overweight (472.7±21.61 m; mean difference 27.42, p=0.0001) and obese children (473.07±23.93 m; mean difference 27.05, p=0.0001), with no significant difference between overweight and obese groups (mean difference 0.37, p=1.000).
Systolic blood pressure response differed significantly across groups (mean change 12.02±4.17 mmHg in normal weight, 8.3±5.62 mmHg in overweight, and 15.8±5.95 mmHg in obese; p=0.00001), with obese children experiencing greater increases than normal weight controls (mean difference 3.775, p=0.005).
Respiratory rate changes showed significant intergroup variance (p=0.0115; obese vs. control mean difference 2.57, p=0.045), while diastolic blood pressure (p=0.2056) and heart rate changes (p=0.0598) did not differ significantly between groups.

Does overweight and obesity alter the cardiorespiratory response and distance walked during a six-minute walk test compared to normal weight in children aged 7 to 10 years?

P

Population

120 children aged 7 to 10 years (58% female) in India divided equally into normal weight, overweight, and obese groups based on BMI percentiles undergoing a single six-minute walk test.

E

Exposure

Six-minute walk test (6MWT) performed according to ATS guidelines in overweight (n=40) and obese (n=40) children.

C

Comparator

Six-minute walk test (6MWT) performed according to ATS guidelines in normal weight children (n=40).

O

Outcome

Cardiorespiratory response and functional exercise capacity assessed immediately pre- and post-6MWT, including distance walked (meters), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), respiratory rate (RR), and rate of perceived exertion (RPE on Borg's scale).surrogate

Main Result

Mean Difference: 27.05

Absolute Event Rate: 473.07% vs 500.12%

p-value: p=0.0001

Overweight and obese children aged 7 to 10 years demonstrate reduced 6-minute walk distance and heightened physiological stress responses compared to normal weight peers, supporting the 6MWT as a practical tool to evaluate pediatric cardiorespiratory fitness.

Implication

Obesity was associated with shorter 6MWT distance and greater SBP rise in children; leaves open whether 6MWT adds value beyond BMI for fitness assessment.

Abstract

Aim: To study the cardio respiratory response to six minute walk test in normal weight, overweight and obese children aged 7 to 10 years. Methodology- An experimental study was carried out to study cardiorespiratory fitness in normal weight, overweight and obese children aged 7 to 10 years.120 children divided into three groups as normal weight, overweight and obese according to percentile chart for age and gender using simple random sampling. Physiological response of children to six minute walk test were evaluated using ( BP, RR,HR ,Distance walked, RPE). Data was documented pre and post 6 MWT and analyzed using ANOVA and Bonefferoni multiple comparison test. Result- Physiological variable showed statistical significant changes were observed in obese grade. When intergroup analysis was done, it was found that obese children showed maximum rise in terms of (SBP, RR, RPE) as compared to normal weight peers. There is no significant difference observed in overweight and obese. And overweight children also showed statistically significant higher response as compared to normal weight peers. Distance covered in six minute was found to be significantly higher in normal weight children as compared to overweight and obese Conclusion - The study concludes that six minute walk test response is significantly higher with higher grades of BMI, which can be effectively used to assess their cardio respiratory fitness.

Ronghe et al. (2019) conducted a cross-sectional in Normal weight, overweight, and obese children (n=120). Overweight and obesity (higher BMI grades) vs. Normal weight children was evaluated on Distance walked in six-minute walk test (meters) (MD 27.05, p=0.0001). Obese children covered a significantly shorter distance in the 6-minute walk test (473.07 m vs 500.12 m, MD 27.05 m, p=0.0001) and had a higher systolic BP rise compared to normal weight peers.
