Regular weigh-ins during clinic visits key to detecting child growth problems early

A baby's weight, measured in kilograms on a clinic scale, tells a story that parents and doctors often miss until it's too late. Child health specialists across Nigeria are pushing a deceptively simple intervention: weigh every child at every hospital visit, plot the numbers on a chart, and tell the parents what you find. It sounds obvious. It isn't being done consistently, and the consequences ripple through the first five years of life, when growth faltering can become permanent.

Dr. Olufemi Akodu, a consultant paediatrician at Olabisi Onabanjo University Teaching Hospital in Sagamu, Ogun State, frames the problem plainly: babies grow fastest in their first two years, and even small changes in weight carry diagnostic weight. A child who stops gaining, or loses weight, may be underfed. Or the child may have an infection—diarrhoea, pneumonia, worms. Or something deeper: heart disease, kidney disease, tuberculosis, HIV. Poor weight gain is often the first visible sign, sometimes the only sign. "When growth problems are identified early, they can usually be corrected more easily," Akodu says. Wait too long, and the damage compounds: severe malnutrition, developmental delays, a weakened immune system that invites further illness.

The World Health Organisation and UNICEF have long identified growth monitoring as foundational to child survival. The first two years represent a critical window for both physical growth and brain development. Yet in many clinics across Nigeria, weighing happens sporadically—perhaps at immunisation visits, perhaps not even then. Healthcare workers measure weight but often do not share the number with parents, do not plot it on a growth chart, do not explain what it means. Parents leave the clinic without knowing whether their child is thriving or faltering.

Akodu and his colleagues argue that this gap is fixable. Healthcare workers should measure not just weight but length or height and head circumference, especially in the first two years when brain growth is rapid. These measurements should be plotted on WHO Child Growth Standards charts. The trend matters more than any single number—a child who gains steadily, even if small, is likely healthy. A child whose curve flattens or drops is sending a signal. "It does not always mean a child is seriously ill, but it should never be ignored," Akodu says. Poor weight gain can point to inadequate breastfeeding or complementary feeding, frequent infections, intestinal parasites, or chronic illness. The cause varies. The response is the same: prompt medical evaluation, not home remedies.

Dr. Ayodele Renner, a consultant paediatrician and child health advocate, emphasizes that growth monitoring functions as both a nutritional assessment and a screening tool for serious disease. A child with tuberculosis, cancer, leukaemia, or HIV may present with growth failure as the primary or only symptom. "Sometimes, the only feature that a child with HIV might present with is growth failure," Renner notes. Early detection allows intervention before the child has lost significant weight or fallen completely off their growth trajectory. Renner also stresses that weighing should happen at every hospital encounter, not just immunisation days. Well-baby checks should continue beyond nine months, when many families stop attending clinics, because substantial growth continues through age two and beyond.

Both doctors emphasize that parents have a right to know their child's measurements and what they signify. When a healthcare worker shares a child's weight, explains the growth chart, and offers concrete feedback—"Your baby has gained weight well, you're doing a fantastic job"—parents become active partners in monitoring rather than passive recipients of care. They learn to recognize warning signs. They understand why nutrition matters. They return for follow-up visits. Renner notes that height monitoring deserves particular attention: some children maintain adequate weight but fall short on height, a sign of chronic malnutrition or other underlying problems. Both weight and height should be measured and charted at every visit.

The practical steps are straightforward. Use a calibrated scale. Measure length or height and head circumference. Take multiple readings and average them for accuracy. Plot the results on a WHO growth chart. Explain the findings to the parent. Educate mothers at every clinic contact—antenatal visits, delivery, postnatal care, immunisation clinics, sick-child visits—about why growth monitoring matters and what to watch for. When a child is not gaining appropriately, investigate promptly: Is feeding adequate? Are infections present? Is there an underlying medical condition? Treat accordingly. Follow up.

What makes this approach powerful is its simplicity and reach. Every child in Nigeria encounters the healthcare system at some point—for immunisations, for illness, for routine checks. Each encounter is an opportunity to measure, to detect, to intervene. The barrier is not technology or cost but consistency and communication. A child whose growth is monitored from birth, whose parents understand what the numbers mean, whose healthcare provider acts on warning signs early, has a fundamentally different trajectory than a child who is weighed once or twice and never told the result. In the first five years of life, when the foundation for lifelong health is laid, that difference is everything.
