You must divide the <strong>weight<\/strong> (in kilograms) by the <strong>height<\/strong> (in meters) squared.<\/p>\n\n<p>Beware of conversion errors: a <strong>height<\/strong> measured in centimeters must be converted to meters before calculation. For example, for a child measuring 110 cm, use 1.10 m and not 110.<\/p>\n\n<h3 class=\"wp-block-heading\">Formula and concrete steps<\/h3>\n\n<p>Step 1: weigh the child without bulky clothes, preferably at a regular time.<\/p>\n\n<p>Step 2: measure the <strong>height<\/strong> with a stadiometer or wall-mounted height scale, heels together and head straight.<\/p>\n\n<p>Step 3: apply the formula: BMI = weight (kg) \/ height\u00b2 (m\u00b2). It is useful to round to two decimals for practical reading.<\/p>\n\n<h3 class=\"wp-block-heading\">Numerical examples for better understanding<\/h3>\n\n<p>Example 1: a 6-year-old girl, <strong>weight<\/strong> 22 kg and <strong>height<\/strong> 1.17 m. BMI = 22 \/ (1.17\u00d71.17) \u2248 16.08. This figure alone does not indicate if it is a normal situation; it must be compared to the reference curve adapted to her age and sex.<\/p>\n\n<p>Example 2: a 10-year-old boy, <strong>weight<\/strong> 38 kg and <strong>height<\/strong> 1.40 m. BMI = 38 \/ (1.40\u00d71.40) \u2248 19.39. Similarly, interpretation will depend on the percentile corresponding to his age.<\/p>\n\n<h3 class=\"wp-block-heading\">Common pitfalls and practical tools<\/h3>\n\n<p>A common trap is comparing a young child&rsquo;s BMI to adult values. Benchmarks evolve with age. There are discs or pediatric calculators at the doctor\u2019s office that indicate BMI in one step.<\/p>\n\n<p>To easily monitor progress, it is recommended to use a validated online calculator or the professional software Calimco, which automatically transcribes the value on the growth chart.<\/p>\n\n<p>Running case: Claire and Marc monitor their son No\u00e9&rsquo;s chart. After a home weighing, they record the BMI, then enter it in the health record book during the consultation. This routine allows anticipating any shift before the situation becomes worrying.<\/p>\n\n<p><strong>Insight:<\/strong> the calculation is easy, but the value takes full meaning when placed on the chart adapted to the child&rsquo;s age and sex.<\/p>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1344\" height=\"768\" src=\"https:\/\/laviedebebe.com\/blog\/wp-content\/uploads\/2026\/03\/IMC-chez-lenfant-comment-determiner-lindice-de-masse-corporelle-des-filles-et-des-garcons-1.jpg\" alt=\"discover how to calculate the body mass index (BMI) in children, with specific advice for girls and boys to better monitor their growth and health.\" class=\"wp-image-1735\" srcset=\"https:\/\/laviedebebe.com\/blog\/wp-content\/uploads\/2026\/03\/IMC-chez-lenfant-comment-determiner-lindice-de-masse-corporelle-des-filles-et-des-garcons-1.jpg 1344w, https:\/\/laviedebebe.com\/blog\/wp-content\/uploads\/2026\/03\/IMC-chez-lenfant-comment-determiner-lindice-de-masse-corporelle-des-filles-et-des-garcons-1-300x171.jpg 300w, https:\/\/laviedebebe.com\/blog\/wp-content\/uploads\/2026\/03\/IMC-chez-lenfant-comment-determiner-lindice-de-masse-corporelle-des-filles-et-des-garcons-1-1024x585.jpg 1024w, https:\/\/laviedebebe.com\/blog\/wp-content\/uploads\/2026\/03\/IMC-chez-lenfant-comment-determiner-lindice-de-masse-corporelle-des-filles-et-des-garcons-1-768x439.jpg 768w\" sizes=\"auto, (max-width: 1344px) 100vw, 1344px\" \/><\/figure>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Interpreting_body_mass_index_according_to_age_and_sex\"><\/span>Interpreting body mass index according to age and sex<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Interpretation of <strong>body mass index<\/strong> in a <strong>child<\/strong> is based on growth charts: benchmarks that take age and sex into account. These charts reflect physiological variations specific to girls and boys.<\/p>\n\n<p>Percentiles are used to locate the child relative to a reference population. A child at the 50th percentile is average; however, a value above the 97th requires special attention.<\/p>\n\n<h3 class=\"wp-block-heading\">What do percentiles mean?<\/h3>\n\n<p>The percentile indicates the proportion of children of the same age and sex with a lower BMI. For example, being at the 90th percentile means that 90% of children have a lower BMI.<\/p>\n\n<p>Usual clinical benchmarks: <strong>BMI<\/strong> below the <strong>3rd<\/strong> percentile = possible underweight; above the <strong>97th<\/strong> percentile = possible obesity. Between these bounds, interpretation depends on the curve trajectory.<\/p>\n\n<h3 class=\"wp-block-heading\">Adiposity rebound: a signal to know<\/h3>\n\n<p>The growth chart generally shows an increase in weight during the first year, followed by a decline until about 5-6 years, then a gradual rise. This rebound point is called the <strong>adiposity rebound<\/strong>.<\/p>\n\n<p>An early rebound, before 5 years, is associated with a higher risk of later obesity. Monitoring the age of this rebound helps with primary prevention.<\/p>\n\n<h3 class=\"wp-block-heading\">Differences between girls and boys and role of context<\/h3>\n\n<p>Pubertal physiology modifies benchmarks: puberty causes hormonal variations affecting <strong>weight<\/strong> and body composition differently depending on sex. It is therefore common to observe fluctuations during adolescence.<\/p>\n\n<p>Family context, genetic history, and ethnic factors influence the interpretation of <strong>BMI<\/strong>. A temporary shift is not always a sign of pathology; contextualized medical opinion is essential.<\/p>\n\n<figure class=\"wp-block-table\"><table>\n<thead>\n<tr>\n<th>Percentile<\/th>\n<th>Interpretation<\/th>\n<th>Recommended action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>&lt; 3rd<\/td>\n<td><strong>Possible underweight<\/strong><\/td>\n<td>Consult doctor for nutritional and growth assessment<\/td>\n<\/tr>\n<tr>\n<td>3rd \u2013 97th<\/td>\n<td>Growth regarded as normal<\/td>\n<td>Regular monitoring with measurements and preventive advice<\/td>\n<\/tr>\n<tr>\n<td>&gt; 97th<\/td>\n<td><strong>Risk of obesity<\/strong><\/td>\n<td>Medical evaluation, nutritional and psycho-social support<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/figure>\n\n<p>Practical example: No\u00e9 is at the 85th percentile at age 4. There is no immediate diagnosis, but the focus is on strengthening eating habits and physical activity.

For <strong>height<\/strong>, use an appropriate height scale, heels together, chin horizontal, and record the value to the nearest millimeter.<\/p>\n\n<p>For <strong>weight<\/strong>, favor a regularly calibrated scale and always weigh at the same time, ideally in the morning after diaper change and before breakfast.<\/p>\n\n<h3 class=\"wp-block-heading\">Practical checklist for parents<\/h3>\n\n<ul class=\"wp-block-list\"><li>Weigh the child once a week at the same time to spot trends.<\/li><li>Measure <strong>height<\/strong> every 1\u20133 months for young children, less frequently for adolescents unless rapid growth.<\/li><li>Record values in the health record book and take a photo of the chart if needed to share with the pediatrician.<\/li><li>Do not compare children of different sexes without considering the charts specific to <strong>girls<\/strong> and <strong>boys<\/strong>.<\/li><\/ul>\n\n<h3 class=\"wp-block-heading\">Tools and resources<\/h3>\n\n<p>The health record book remains the basic tool. The official Ministry of Health charts and the Calimco tool allow precise visualization.<\/p>\n\n<p>Online, calculators adapted for ages 2\u201319 communicate a Z score in addition to <strong>BMI<\/strong>, which is especially useful for professionals and families requiring precise follow-up.<\/p>\n\n<h3 class=\"wp-block-heading\">When to consult?<\/h3>\n\n<p>If the chart shows an abnormal slope \u2014 rapid rise or persistent drop \u2014 consultation is recommended. A warning: never place a child on a diet without the advice of a health professional.<\/p>\n\n<p>During the consultation, bring the health record book with the chart, meal photos if needed, and any information on daily activity and sleep.<\/p>\n\n<p>Family story: Claire and Marc began noting No\u00e9\u2019s measurements in an app then compared them during the pediatrician visit. This exchange allowed anticipating simple nutritional advice and avoided unnecessary worry.<\/p>\n\n<p><strong>Insight:<\/strong> regular measurements and clear transmission of information to the professional allow rapid and appropriate action.<\/p>\n\n<figure class=\"is-provider-youtube is-type-video wp-block-embed wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"IMC : calculer et  comprendre l\u2019Indice de Masse Corporelle - Coaching Nutrition\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/lCk7wg75_R8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"When_to_worry_and_what_concrete_actions_to_take_to_prevent_excess_weight\"><\/span>When to worry and what concrete actions to take to prevent excess weight<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>It is normal to question when a chart deviates from the norm. Warning signs include a rapid rise in <strong>BMI<\/strong>, an early adiposity rebound, or psychosocial signs such as withdrawal or teasing at school.<\/p>\n\n<p>The goal is not to stigmatize but to protect <strong>child health<\/strong> and the child&rsquo;s self-confidence.<\/p>\n\n<h3 class=\"wp-block-heading\">Physical and behavioral signs to observe<\/h3>\n\n<p>Physically: shortness of breath on exertion, unusual fatigue, joint pain in overweight children should alert.<\/p>\n\n<p>Emotionally: isolation, low self-esteem, body anxiety, or eating behavior disorders require multidisciplinary care.<\/p>\n\n<h3 class=\"wp-block-heading\">Therapeutic and preventive approach<\/h3>\n\n<p>The first step is a pediatric consultation to rule out medical causes. Then, a personalized plan often includes a nutritional assessment, encouragement of adapted physical activity and, if necessary, psychological support.<\/p>\n\n<p>Strict diets must be avoided. Gradual modifications of the family environment \u2014 regular meals, reduction of sugary drinks, daily playful activities \u2014 are more effective and respectful of development.<\/p>\n\n<h3 class=\"wp-block-heading\">Concrete example: No\u00e9\u2019s journey<\/h3>\n\n<p>At 5 years old, No\u00e9 has a slowly rising BMI. Rather than imposing punitive rules, the parents introduced simple habits: protein-rich breakfast, outdoor play after school, and screen time limited to 30 minutes after class.<\/p>\n\n<p>After three months, the chart stabilized and the pediatrician confirmed better overall energy. The gentle approach preserved the parent-child relationship and avoided any guilt.<\/p>\n\n<p><strong>Insight:<\/strong> early and benevolent intervention, prioritizing sustainable habits rather than strict control, is the safest strategy to preserve the child&rsquo;s overall health.<\/p>\n\n<figure class=\"is-provider-youtube is-type-video wp-block-embed wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Calculez votre Indice de Masse Corporelle IMC\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/lG25fyaeIn4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nutritional_advice_and_family_habits_for_balanced_growth\"><\/span>Nutritional advice and family habits for balanced growth<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Preventing overweight is part of daily family life.
