Abstract

Obesity can affect body balance in women due to changes in weight distribution and shifts in the centre of gravity that reduce postural stability. This study aimed to determine balance levels and examine the relationship between Body Mass Index (BMI) and balance in obese women. A quantitative correlational design with a cross-sectional approach was used. Thirty-six obese women were selected through purposive sampling. BMI was calculated from weight and height, and balance was measured using the Stork Balance Test, recording the best of three trials. Pearson’s correlation test was applied at a 5% significance level. The mean BMI was 32.15 ± 4.22 kg/m². The average balance time was 3.80 ± 2.40 seconds for the right leg and 3.46 ± 2.18 seconds for the left leg, both categorized as very poor (<5 seconds). A significant negative correlation was found between BMI and left-leg balance (r = −0.347; p = 0.038; 95% CI = −0.60 to −0.02), while no significant correlation was found for the right leg (r = −0.188; p = 0.272; 95% CI = −0.49 to 0.15). Higher BMI was associated with poorer balance only in the left leg, indicating a side-specific relationship. These findings support the need for balance and muscle-strengthening programs for obese women.

Abstract

There is a need for instruments with good validity and reliability to assess three domains of responsive feeding practices in early childhood in Indonesia. This study aims to analyze the validity and reliability of the responsive feeding knowledge, attitude, and practice instrument, which was developed for children under three years old. A cross-sectional design examined the validity among diverse toddler parents. The variables studied include knowledge, attitude, and practice of responsive feeding. The questionnaire is structured as doing or not doing practice, attitudes in true or false statements, and knowledge in multiple-choice questions. The construct validity of the Responsive Feeding Knowledge, Attitude, and Practice questionnaire (RF-KAP Q) was evaluated by determining the Pearson correlation coefficient values for each item with the overall score. Additionally, a reliability test was performed to assess the internal consistency of the questionnaire. Cronbach's alpha coefficient measured internal consistency. The 20 items of responsive feeding knowledge questions were categorized as valid; two items were categorized as constant (K6 and K7), and one other was classified as invalid (K14). A total of 25 attitude statement items were considered valid. All practice indicators consisting of 12 statement items were categorized as valid (p-value<0.05). The Cronbach's alpha of the responsive feeding knowledge, attitude, and practices questionnaire was 0.677, 0.699, and 0.778, indicating reliability. The RF-KAP Q has been tested as valid and reliable in measuring three domains of responsive feeding based on evidence-based recommendations in Indonesia. However, development is still needed to improve its validity.
