WHAT THE EVIDENCE SHOWS

How to spot an eating disorder in a teenager

Disordered eating is far more common in adolescents than most parents realise, and weight is a poor guide. A pooled analysis found about 22% of children and teens screen positive, and girls far more than boys.

WHAT THE GUIDELINE ACTUALLY SAYS

How much sleep do children need? The consensus figures, by age

There is no single number. A US expert panel sets wide bands — 12 to 16 hours for infants down to 8 to 10 for teenagers — and warns that regularly falling short is linked to attention, behaviour and learning problems.

WHAT THE EVIDENCE SHOWS

How much exercise do teenagers actually need?

The global target is an average of 60 minutes a day of moderate-to-vigorous activity, plus muscle-strengthening. Most adolescents miss it: in 2016, 81% worldwide were insufficiently active, and girls more than boys.

EXPLAINER

Childhood eczema: what actually calms the itch

Regular moisturisers and short courses of topical steroids are the mainstays, with modest trial support. Most children improve with age, and popular add-ons like bleach baths are no better than plain water.

EXPLAINER

Childhood constipation: why more fibre is not the fix

Most constipation in children has no underlying disease. Guidelines say the treatment that works is a laxative — clearing the backlog, then a maintenance dose for weeks — not simply adding fibre or fluid.

EXPLAINER

What the newborn heel-prick test actually screens for

A few drops of blood taken in the first days of life are checked for dozens of rare but treatable disorders. The US panel has grown from 29 conditions to 35, and states adopt each one at very different speeds.

WHAT THE STUDY ACTUALLY SAYS

Adolescent depression: what the evidence says actually helps

In the largest trial, combining fluoxetine with talking therapy helped most, and both worked better than placebo. A later network analysis found only fluoxetine, alone or with therapy, clearly beat placebo.
