The most crucial element in evaluating a child’s health is proper growth. A gain in height and body weight are two ways to show growth. Since puberty is a time of major emotional and physical changes to the body, it may be a stressful and worrisome time for teenagers and their families. Males typically reach puberty between the ages of 9 and 14, and females between the ages of 8 and 13. Breast growth, or thelarche, is the initial indication of real puberty in females. The first symptom is testicular enlargement in males, which occurs when the testicles grow to a length of 2.5 cm or a volume of 4 ml or more. Environmental conditions are one of the elements that influence the time and pace of pubertal development. This article explains the influence of excess weight on the onset of puberty.
What is obesity, and how is it different from being higher weight?
A healthy child can be identified by various means, such as daily habits, diet, BMI changes, and sleeping patterns. It is often considered that someone looking a certain way and fulfilling certain criteria can be classified as healthy, but the actual examination comes from a doctor. However, to still study how a healthy person should look, we can consider the following aspects:
- Monitoring waist circumference
- Evaluating BMI – A normal BMI ranges from 18.5 to 24.9
- Keeping track of physical activity
- Assessing strength and endurance
On the other hand, a person is considered to have a higher weight if their body weight exceeds what is considered appropriate for their age, height, and/or body frame.
Girls tend to have higher weight than boys during certain developmental stages. Also, if BMI is the recommended way to express a group’s body fat percentile during adolescence.
Excess weight is generally defined as having a BMI between the 85th and 95th percentiles and obesity is defined as having a BMI higher than the 95th percentile.
While BMI is a useful screening tool, obesity is majorly thought to be better defined by body fat percentage (BFP).
How does excess weight cause delay in puberty?
Excess weight gain can be a major cause of delayed puberty or other pubertal disorders in children. The hormone leptin, which is primarily engaged in energy control and is produced by adipose tissue, is one of the most significant elements. Leptin normally serves to signal the brain to trigger that may rise with increasing weight, leading to leptin resistance. Leptin resistance makes the body less sensitive to the hormone’s signal, interrupting the hormonal cascade necessary for the onset of puberty.
In addition, weight gain may also be linked to insulin resistance and chronic inflammation, which can both impair the hypothalamic-pituitary-gonadal (HPG) axis. This axis regulates the release of pivotal reproductive hormones like LH (luteinising hormone) and FSH (follicle-stimulating hormone) that are vital for sexual development. Interference with this hormonal signalling can ultimately affect the production of oestrogen or testosterone, thereby delaying or slowing down puberty.
The onset of puberty is also influenced by lifestyle choices, particularly those related to food and sleep. Unhealthy eating habits, whether caused by consuming too many unhealthy foods or not enough healthy ones, can lead to nutritional imbalances that may affect hormone levels and developmental milestones. Excessive consumption of high-calorie, low-nutrient foods that increase body mass index can impair the body’s ability to support healthy growth and reproduction.
It is also necessary to understand that psychological causes may also be involved. Adolescents, particularly males, may develop emotional eating as a result of isolation or psychological disorders. On the other hand, girls with pressure or stress from society could develop eating disorders, such as overeating or extreme restriction of food consumption—both of which could affect puberty through hormonal and nutritional disturbances.
How can parents keep their children from gaining excess weight?
It is possible to avoid excess childhood weight gain by intervening early, when the body’s biochemistry and habits are still largely unaltered. These interventions must begin in early childhood, with parents having a strategic role to play in influencing their children’s health and healthy lifestyle from a young age. In addition to controlling their food consumption, parents must keep an eye on their children’s weight, eating habits, and activity habits.
- School-based approaches: By promoting whole grains and low-fat dairy products while preventing all sugar-sweetened beverages, children are more likely to develop better eating habits both at home and at school, reducing their risk of gaining weight. Apart from healthy eating, the incorporation of school-based physical exercises, sports, and nutrition education can help increase aerobic capacity and improve BMI.
- Healthcare-based strategies: Several paediatricians have noted certain obstacles in the children’s growth, such as lack of motivation in parents and children, family history of obesity, and unhealthy family habits. Hence, these strategies might involve consulting doctors for frequent check-ups as well as following the growth of the child by frequent calculation of their BMI.
- Home-based solutions: These may help in the identification of the growth barriers by focusing on the inability of other family members to adopt the habits and by improving access to physical activities as a replacement for excessive screen time.
Conclusion
Childhood and adolescent development are influenced by environmental and genetic determinants, one of which is nutrition. Excess weight in early life is known to interfere with normal growth and is associated with both short- and long-term metabolic and cardiovascular risks. In addition, weight gain may also cause delayed puberty because of imbalances in hormones and the accumulation of fat, which may alter the onset of puberty, calling for an early intervention.
