Changing Nutrition Scene In South Asiac. Gopalan
The countries of South Asia,(Bangladesh, Bhutan, India, Maldives,Nepal, Pakistan and Sri Lanka) with1.3 billion people account for 37 percent of Asia's population and 22 percent of the population of the world.International reports such as the Human Development Report' have accorded a low ranking to some of thesecountries in the developmental scale.While the validity and utility of theseinternational ran kings can be challenged, it must be conceded that thecountries of South Asia have facedand are still facing major problemsrelated to undernutrition.
However, the present situationin these countries has to be seen andunderstood in the total historical context. Practically all the countries ofthis Region could be considered tohave started on their developmentaljourney just five decades ago, withthe attainment of their political independence. During the last five de~cades these countries have, in fact,registered some remarkable gains andthese must be recalled:
• Large-scale famines, which usedto devastate vast sections of the population of this Region with distressingregularity for centuries, have beeneliminated.
• Florid forms of malnutrition suchas beri-beri (cardiac and dry), pellagra, keratomalacia, famine edema, classical kwashiorkor, pendulous goitresand osteomalacia have been eliminated. The Indian subcontinent was averitable museum of these most florid
forms of undernutrition. These havenow ceased to be the major publichealth problems, which they once were.
• Cereal (wheat and rice) productionhas nearly kept pace with populationgrowth, ensuring that the per caputavailability of food grains has notdeclined. This has been achieved in
spite of a tremendous population riseduring the past 50 years, from456 million in 1950 to 1.3 billion in2000.
• Death rates of infants and childrenhave been drastically reduced andlife expectancy has risen (Table 1).
THE UNFINISHED TASKS
While the gains of the past havebeen impressive, a great deal moreneeds to be done before the problems of poverty and malnutrition inthis Region are fully eliminated. Thetasks ahead are indeed formidable.Four such major tasks that requireour immediate attention are mentionedbelow.
Food production: 'Food security' of earlier years was largely lookedupon as a quest for freedom fromstarvation and hunger. The calorieadequacy yardstick has been themeasure of achievement in this regard. Unfortunately, the Green Revolution, which saved the lives of millions in this Region, has led to somedistortions with respect to the patternof food production. Thus, whereascereal production had soared, theproduction of pulses (poor man's pro-
tein) has stagnated with the resultthat the per capita availability of pulseshas actually declined2• Horticulturaldevelopment has been very tardy. Withregard to milk production, India hashad some striking results, largely dueto the imaginative co-operativeprogrammes of the type initiated byDr V. Kurien.
On the whole, the production of"quality foods" has not kept pace withincreasing requirements. The resulthas been that there has been no significant improvement in the quality ofhousehold diets. Durable improvementin the nutritional status of populationscan be achieved only by ensuringqualitative and quantitative adequacyof household diets. This is a majorchallenge.
It will be a formidable task tomeet the increased demands (Table2) for quality foods by the end'of thenext decade in the context of shrinkage of land size holdings, scarcity ofwater and electric power and declining yields per hectare. Clearly newimaginative strategies and safe newtechnologies will be needed to achieveadequate production of a range offoods.

300623006644- Anti-poverty programmes in thisRegion have been generally undertaken as short-term relief operations,which would yield immediate relief.These may be justified perhaps indealing with situations of distress likedroughts and floods. The poverty syndrome has many synergistic attributes.(Figure 1) The problem of povertycannot be "solved" or pushed underthe carpet through populist reliefprogrammes. Our strategy must be toattack the root causes of poverty ratherthan its symptoms. Even modest inputs addressed to the alleviation ofroot causes of malnutrition in a plannedmanner, converging on a populationgroup, would yield significant results.Relief programmes could be an adjunct to this effort.
The central part of any such strategy should consist of programmesfor the aggressive spread of education, especially female education, andfor imparting income-generating skills,which would facilitate creation of largenumbers of blue-collar jobs. It is throughsuch efforts, which are calculated toimprove the quality of our human resources, and not through short-termrelief operations, that we can hopefor a durable solution of the povertyproblem.
Child survival and stunting: Whilethere have been striking improvementswith respect to child survival, this hasyet to be followed up to the point ofachieving optimal child health/nutri-

have been reduced3. The fact thatthere has been an emergence of anurban middle class in the last decadenumbering over 200 million, presumably including a sizable number of'first-generation rich', would also indicate thatthe anti-poverty programmesare having an impact. Subsidised foodgrains at low prices are now beingmade available to the poor and attempts are now being made to evolvea more effective public distributionsystem. All the same, new imaginative strategies are necessary to combat poverty and quicken the pace ofpoverty eradication in this Region.

Ensuring adequate access tofood: Much of the undernutrition seenin South Asia is attributable to the factthat sizable sections of the population do not have adequate access tofoods. We are, therefore, witness tothe cruel paradox of vast stocks offood grains posing storage problems,on the one hand, and sizable pocketsof undernutrition, on the other.
It has been claimed, on the basis of certain criteria, that 30 per centof the population of the Indian subcontinent could be below the povertyline. Several anti-poverty programmeshave been undertaken in this Region.While these may not have succeededin eradicating poverty, they have certainly helped to mitigate it. Disaggregated data analysed by the NationalNutrition Monitoring Bureau (NNMB)at National Institute of Nutrition (NIN)show that severe degrees of poverty

tion. With modern health technology,it is possible to successfully applydeath control strategies even in thecontinuing context of poverty andundernutrition. As a result of a policywhere the chief objective was "childsurvival" ratherthan child health, therehas been an expanding pool of substandard survivors. Thus, more than50 per cent of children in this regionare stunted according to available reports. (Table 3)
Much has been written aboutstunting and quite a few gloomy conclusions about the state of child healthin this Region have been drawn onthis basis. However I would like tosound a note of caution. We must
perhaps avoid drawing sweeping conclusions regarding the state of childhealth in a country just on the basis ofprevailing heights of children in comparison with an international standard.So-called "stunting" is after all a nonspecific sign of multifactorial origin. Itcannot be considered as the 'GoldStandard' for evaluation of the childhealth of a nation. It is not stuntingper se, but the process that led to itand the precise factors involved in it,that lend it significance, These maynot be the same in all communitiesand in all stages of development.
There has always been a secular trend in all developing countries,children of succeeding generationsbeing taller. According to reports, ittook 50 years (1880-1930) forthe seculartrend in Canada to plateau off. It maybe wrong to argue that Canadian children were stunted for nearly five decades. Similarly in Japan, the seculartrend has been on right from the endof World War II. Elimination of stunting is, therefore, apparently a multigenerational phenomenon.
There is already some evidenceof secular trends with respect to heightseven among poorer sections of thepopulation3. We should promote thissecular trend, so that the populationsachieve the heights which are reflective of their genetic potential.
Maternal health: An unfinished
task that must find high priority isnutrition care of the pregnant woman.Today nearly 80 per cent of pregnantwomen in this Region are anaemicand, even more importantly, nearlyone-third of infants born to them are
of low birth weight. The diets of pregnant women in poor communities inSouth Asia are as poor, if not evenpoorer, than those of non-pregnantwomen.
Recent studies have indicatedthe long-term implications of low birthweights and intra-uterine growth retardation. In a long-term study extending over 18 years, Shanti Ghoshand her colleagues as reported byS.K. Bhargava and V. Kapani4. hadshown that low-birth-weight infantscontinue to grow and develop in asubstandard growth trajectory as compared to children of the same socioeconomic groups born with normalbirth weights. This would indicate thelong-term implications of intra-uterine growth retardation on subsequentgrowth in childhood. It is possiblethat some part of the stunting that wesee may be attributable to intra-uterine growth retardation.
More recent studies of Barker
and colleagues5 have indicatedthat subjects born with low birthweight are more vulnerable to chronicdegenerative diseases such as Syndrome X and Type II diabetes in adulthood. This finding must be of special
3
concern to us, considering that WE
have, on the one hand, a high inci·dence of low-birth-weight deliverie~and, on the other hand, an escalationof chronic degenerative diseases inadulthood.
An important factor, which hasnot attracted adequate attention, bulwhich probably contributes significantlyto low birth weight and intra-uterinegrowth retardation is that the gestational age of live born infants in thepoor communities6 appears to be significantly shortened as compared tothose in the developed countries7,8(Table 4). Shortening of gestation periodseems to be an important attribute ofmaternal undernutrition. Even among"full-term births" in poor communities, a high proportion of deliveriestake place in the 37th and 38th weekand not in the 39th and 40th week6,
Preliminary results of recent studies undertaken by the Nutrition Foundation of India (NFl) show that regulardaily supplementation of iron and folateto pregnant women can significantlycontribute to reduction in the incidence of low birth weights. However,we did not find a linear relationshipbetween the severity of anaemia andlow birth weight. On the other hand,the addition of food supplementscontaining n-3 fatty acids (such assoya oil) over and above iron-folatesupplements could significantly correct the shortening of gestation andincrease birth weights. The beneficialeffect of iron-folate supplementationmay be at least partly due to thefact that it facilitates the conversionof n-3 fatty acids to their activemetabolite (Figure 2).
If extended studies, which arenow ongoing, confirm these findings,

of undernutrition and poverty withproblems related to unbridled and illregulated affluence. For the next 20years, South Asia will have to fight attwo ends of the developmental spectrum. It must attempt to achieve complete elimination of undernutrition andpoverty, on the one hand and thedisturbing escalation of chronic degenerative diseases among the affluent sections, on the other.
Information technology revolution: Information technology hasmade rapid advances in the past fewdecades and continues to do so. Radio and television media have beenbringing information into the homesof largely illiterate populations, therebyopening a window to the world. Satellite imagery has been providing valuable inputs about ground water resources, soil quality, weather, anddesirable cropping patterns. And now,with computers penetrating slowly but

this section also appears to be themost vulnerable to chronic degenerative diseases such as obesity, Type IIdiabetes, Syndrome X, etc, becauseof changed lifestyles and dietary habits1O• There has been a debate as to
whether this vulnerability is genetically determined or whether it is atransitional phenomenon arising fromthe fact that this middle class, sizablesections of whom have presumablybeen born in poverty and have acquired affluence in adulthood alongwith life-style changes associated withsuch affluence.
Whatever may be the explanation, the escalation of chronic degenerative diseases poses a serious problem. It would almost appear that SouthAsia may be exchanging its problems

FACTORS INFLUENCING FUTUREDEVELOPMENT
we would have placed in the hands ofhealth workers valuable informationregarding precise inexpensive andpractically feasible directions in whichdiets of pregnant women can be improved. There are several inexpensive foods which could supply bothiron/folate and essential fatty acidsavailable in this Region (Table 5).Ourattempts should be to promote theintake of such foods rich in iron and
essential fatty acids which are specially rich in n-3 fatty acids for pregnant women.
The major factors which are boundto have a profound influence on thenutrition scene of this Region are thefollowing: urbanization, informationtechnology revolution and globalisation.
Urbanisation: A major changein the last few years has been thelarge-scale movement of rural populations to urban areas (Figure 3).Urbanisation implies not just a changein the location of the dwellings, butalso a change in life styles, value systems and dietary habits. Whileurbanisation has had its positive effects and has contributed to overalleconomic growth, it has also led toundesirable side effects. There hasbeen a rapid emergence of a newlyaffluent middle class (prone to dietary errors and excesses) in the Indian subcontinent9. This new middleclass has been, in many ways thespearhead of economic and overallnational development. Unfortunately,
surely into district, block and evenvillage levels, the wide world of theInternet is only a mouse-click away.
Governments, including localgovernments, and development scientists can leverage these availableinputs in imaginative and innovativeways to enhance nutrition information, hygiene awareness, better farming practices and so on. Web pagesin regional languages will acceleratethe process of reaching target groups.A planned strategy to harness the fullpotential of information technologymust form an important part of anydevelopmental programme. Knowledgeis power. The best way to empowerthe poor and the vulnerable sectionswill be to equip them with knowledgeusing the modern tools of informationand technology. This could be a powerful help in combating poverty.
Globalisation: Globalisation
could certainly contribute to macroeconomic development. But as KhadijaHaq cautions1, "If globalisation is superimposed on apoorly educated andpoorly trained labour force with poorsystems of governance and infrastructure, it would not lead to growth norreduce poverty". Unless globalisationis accompanied by institutional changesand by rapid improvement in the educationallevels of the poorest sectionsof the population, there could be afurther polarisation between the havesand the have-nots. The advent of
globalisation greatly adds to the urgency of the need for upgrading thequality of the poorer sections of society through the spread of educationand imparting of income-generatingskills.
In pursuing developmental objectives, Asian countries should notmake the mistake of accepting the'western model' as perfect. It must beremembered that western countrieshad made many dramatic U-turns suchas return to breast-feeding, jettisoning high saturated fat diets andrecognising the importance of vegetables. Asian countries should seekto foster and cherish traditional practices that have been proved to beconducive to general health and wellbeing. At the same time they shouldbe receptive to new ideas and newtechnologies of proven value and safetyfor combating undernutrition.

• IX Asian Congress of Nutrition:The IX Asian Congress of Nutritionwas held at Hotel Ashok, New Delhifrom February 23-27,2003. India washappy to host the Congress for thesecond time. The First Asian Con
gress of Nutrition was also hosted byIndia and was held in 1971 at
Hyderabad. The President of the IXAsian Congress of Nutrition, Dr C.Gopalan was also the President ofthe First Asian Congress of Nutritionand he was the one who had initiatedthis series.
Mr K.C. Pant, Vice Chairman ofIndia's Planning Commission, presidedover the Inaugural Function anddelivered a scintillating and informative address indicating the proposedsteps that would be taken by the Gov-

ernment towards nutritional upliftmentof the population. This comprehensive address will form part of the Proceedings of the Congress.
The Congress was organised bythe Nutrition Society of India and theNutrition Foundation of India underthe auspices of the Federation of AsianNutrition Societies (FANS). It was attended by over 1,350 delegates fromover 46 countries. The ScientificProgramme consisted of 6 PlenaryLectures, 6 Plenary Sessions, 30 Symposia, Oral Free Communication andPoster Sessions.
The Scientific Programme presented a proper balance between thebasic scientific aspects and practicalapplications. The Congress providedan opportunity for scientists from different countries to interact with eachand share experiences.
Dr C. Gopalan was elected asthe President of FANS and Dr RameshV. Bhat as the Secretary General. Itwas unanimously decided that the XAsian Congress of Nutrition will beheld in Taipei.
• Third Course in Practical Paediatric Nutrition: The Third Course inPractical Paediatric Nutrition was jointlyorganised by the Centre for Researchon Nutrition Support Systems (CRNSS)and the Apollo Centre for AdvancedPaediatrics (ACAP) on March 8-9, 2003in New Delhi. In contrast to a largeCongress, the primary objective ofthe Course was to provide a practicalapproach to the administration of enteral and parenteral nutrition in thehospitalised child and was intendedprimarily to target the practicing clinicians and dieticians. The Course wasattended by over 60 delegates whohad the opportunity to interact withthe faculty through intensive brainstorming sessions, involving practical day-to-day problems encounteredduring the nutritional management ofcritically-ill patients.
