Weighing babies and tipping the balance on malnutrition: Under 5 mortality in rural Tanzania

Silent, screaming grief mixes with the hot stagnant air. I stand beside a rusting hospital bed holding a kitenge. These vividly coloured wax printed sheets adorn Tanzanian women everywhere, as skirts, headscarves, baby carriers. Today, the one in my hands is a shroud. A grandmother stands next to me. She cries as I pull it over the cold, motionless face of a three month old baby.

The day started badly. I am frantically busy as I round the hospital alone. All the doctors have been ordered to attend a government seminar. We were informed of this by text message last night. If I wasn’t here, I’m not sure who they would have expected to see the patients. I visit Elena, a 17 year old girl with typhoid. The disease is endemic here. People do not have well-dug toilets and raw sewage filters into rivers. They cannot spare firewood to boil river water to kill the bacteria before drinking it. Typhoid thrives. This young woman caught the bug, got sick, and her bowel burst open inside her. Last week we opened her abdomen to scoop out the infection and repair the hole. It was a mixed success. Her life was saved but several days later the infection came back and her wound burst open. She now leaks fluid from a small gap in the surgical incision site. I examine her and clean her wound. She is a shadow. She has the build of a skinny 10 year old girl, and the face of a much older woman. Her skin clings to her. Every vessel, bone and muscle is visible. She sits uncomfortably on her bed staring at the wall. I encourage her to eat and write some more antibiotics.

Her grandmother is speaking fervently in the local language, Kikaguru. She is clutching a bundle of blankets, and starts to cry. A student translates- Elena has a 3 month old daughter which she is unable to feed because she has stopped producing breast milk. Her family didn’t know what to do. They fed the baby with unpasteurised cow’s milk, leading to a diarrhoeal illness with fevers of 42 degrees. They have since been feeding with over-diluted formula milk. A tin designed to last three days is almost full, one week on. They can’t read the instructions and want to ration the expensive milk. I flick through the case notes and no one in the hospital seems to have offered them any other advice.

I carefully unwrap the child. She is unconscious, thin, floppy, has oedema from malnutrition, and cannot feed. Her lips are dry and cracked, covered by the white spots of oral thrush. I carry the fragile, limp bundle to the children’s ward where we give her glucose, antibiotics, and a small amount of fluid through a vein in her scalp, wrap her up warm, and cautiously drip formula milk through a tube in her nose. She carries on deteriorating, and despite resuscitation dies several hours later.

I inspect the body. It is unspeakably terrible to see a still, lifeless baby. Is she at peace? I close her eyelids. She almost looks serene. Her great-grandmother unwraps the kitenge from her shoulders and hands it to me to wrap the baby. I say sorry. “Pole, Bibi”. I’m sorry, for my failure, for the failure of the hospital, for the cruel workings of the world which have led to you wrapping a funeral veil around your great-granddaughter. Bibi you have been crying since yesterday, and you feel this is your fault for not caring for the baby well. I feel angry, sad, and nauseous all at once. It will take me a while to get over this one. I know that you will never really recover.

They say that two wrongs don’t make a right. Using the same perversion of moral algebra I guess you could also say that two rights don’t correct a wrong. But some days working in this hospital is like wading upstream. Sometimes you have to remind yourself of the successes just to keep your head above water. This week we are nursing two children back from malnutrition. Slowly they are improving. My resources are limited. I cannot afford the expensive malnutrition feeds the WHO recommends so I make up my own, using powdered milk, sugar, oil, cereals, and added vitamins and minerals. Children are living.

Malnutrition is the scourge of children worldwide, and contributes to a staggering 50% of deaths of under 5s. About once a month we see a case of the most severe type- a skeletally thin marasmic child, or one swollen and lethargic from kwashiorkor. Even with the best treatment, 1 in 3 of these will die. But collectively the biggest burden is from chronic rates of mild and moderate malnutrition. These children would otherwise survive an episode of diarrhoea or measles, but deprived of the building blocks for health- vitamins, minerals, and calories- the balance is tipped against them. The problem starts with a diet of carbohydrate rich and nutrient deficient staples like maize, and is worsened by drought and inefficient farming methods. A malnourished child is more likely to get an infection, which in turn worsens their malnutrition, leading to more diseases and a deadly downward spiral. The solution starts with prevention. This year’s G20 focussed on optimising agriculture in Africa as an essential and enabling step out of the poverty trap. The average modern African farm is less productive than an American farm 100 years ago. The continent is rich with agricultural heritage, land and willingness to improve. Something, soon, must tip the balance and unlock this potential. Maybe this will be do-gooders from abroad. I suspect the important change will more likely come from within.

I end the day covering the outpatient department. My last patient is a happy, drooling, chubby-legged 8-month old boy. I joke with his mother that he is very fat. She glows with pride. The child is in fact not overweight, but merely in the statistically permissible upper limit of what the WHO would call normal. But after my 4 months here, and weighing hundreds of sick children, this is one of an exclusive handful which have either achieved or mildly exceeded their expected weight. He has pneumonia, but no danger signs. Because he is well-nourished he will likely weather the illness well.  He escapes home with a bottle of antibiotics and a follow-up appointment. I wave goodbye to him, and he grins happily, tied snugly to his mother’s back by a colourful kitenge.
