Health : A major Paradigm in Anthropology.  

Under the evolutionary framework health is a paradigm in Anthropology; as the health status of a community is a very good indicator of adaptation to an environment (includes physical, biological and cultural).  The major goal of anthropological research is to understand the      as also to unravel the intricate mechanism of human variation and evolution.  Health and well-being is one of the major indicators of overall development or progress of a community or a nation.  Since man is a bioculturally integrated entity, health condition is a result of the interaction of both biolological and SOfactors.     

This multidisciplinary programme is being carried out since  1976 following in broad outlines and supplementing the recommendations of  the  Human Adaptability Section, IBP, Man and  the  Biosphere Programme, UNESCO and The Decade of the Tropics, IUBS. The general objectives of the programme are (a) to evaluate the nutritional and health status of communities exposed to various  physical, biological and sociocultural environments and/or having different  genetic  compositions; (b) to identify and measure the  roles  of factors associated with these environments, their relative  roles and  interaction  effects,  and/or of  genetic  compositions,  in determining  the same; (c) to detect the effects of human  health and  activity patterns on the environment; and the survival (coping) strategies adopted by the disadvantaged population to withstand the insult of the changing and adverse environment and eventually (d)  to determine the limits to human adaptation.
        
The limits to human adaptation are defined in the following terms :  

(a) lower limit--the magnitude(s) of stress(es)  beyond  which survival  is not possible; and (b) upper limit--the  magnitude(s) of  withdrawal of stress(es) and/or input of favourable  stimulus  beyond which the chances of well-being and survival does not increase.

The programme should ideally operate at two levels :

(a)  undertaking  small scale, intensive studies on some  selected  populations  of West Bengal (selected on the basis of certain  environmental factors, e.g., altitude, climate, rainfall, disease vectors, social/economic conditions, etc.), to detect the effects of specific  environmental factors on individual health  and  nutritional traits, as well as the effects of specific  health/disease and  activity  patterns on the environment;  and  

(b)  generating basic  data on health and nutritional characteristics of  populations from various ecological zones of West Bengal in particular and India in general, from  different ethnic groups within a zone and from different socioeconomic strata  within  an ethnic group, the states  and  strategies  for survival and the degrees of ecological success, through carefully designed  sample surveys. The former approach may provide  important indications as to the determinants and consequences of human health  and  nutritional  patterns, and  thereby  suggest  useful intervention  points;  the latter should provide  objective  data base for formulating community health policies and programmes, in addition  to providing opportunities for testing the  above  mentioned indications and suggestions.

The small  scale, intensive type of work carried out  under  the Human Adaptability Programme has produced interesting results. In order  to  pursue this line of work on a long-term  basis  (10-15 years,  say)  and to expedite its progress so as to  obtain  some comprehensive  results within a reasonable period of time, it  is necessary  to  place  the programme on a  permanent  footing  and providing it with certain essential facilities. Collaboration  of scientists  from other disciplines are available at  present  and will be sought in future, as necessary.

        

Project already completed

Project 1: Impact of Altitude on Human Populations.


Thrust areas:  

(a) Is the effect of high altitude a universal  phenomenon  in the  human  case?

(b) What are the relative effects  of  physical environmental,   biological  and  sociocultural   factors/factor-complexes  on individual health traits and a composite  index  of health  that  we may try to define?

(c) What are the  impacts  of human activity on environment (e.g., of population influx, industrialization,  etc. on forest destruction, soil erosion,  disruption of traditional values, inter-ethnic group conflicts, etc.).
        
Outcome :  The results suggest that although altitudinal  differences exist for many human biological traits for instance, delayed menarche, reduced fertility, higher haematological values, lower blood pressure, slower and protracted child growth, and absence of adolescent growth spurt, expansive chest, higher body fat as expected, but the adults are taller and heavier than their low altitude counterparts, similar  difference exist  between/among sociocultural, ethnic, etc. groups as  well, so that altitudinal differences may not be due to altitude related  physical  environmental factors per se. A  possible  lack  of universality  in the capacity for biological responses  of  human populations   with   respect   to   one   or   several   adaptive domains/traits  may result in a given trait responding  differentially  to the altitude stress(es) in  different  regions/populations,  and  different traits responding  differentially  to  the altitude  stress  in a given region/population. It  thus  appears that  some of the apparently altitude related differences may  be caused  by  complex and varied  region-  and  population-specific interactions of physical environmental and socio-cultural stresses as  well as genetic make ups. Human activities and the influx of tourists in the regions have gravely affected the mountain ecosystem. The study also shows that modernization affects life ways of the people in this harsh and extreme environment. The study also suggests that adaptive pathways of the Asian highlanders are different from Andian highlanders.   The latter findings are in conformity with by and large experimental animal models.  The former may be due to longer history of residence at high altitude, and warranty further research to resolve the riddle pertaining to adaptive mechanisms.  

        

Project 2. : A study on the Determinants of Fertility and Mortality in  an Urban Setting : An Anthropological Perspective,  


One  major objectives of the goal of "Health for All by 2000"  is to  reduce the maternal and child morbidity and mortality,  which are extremely high in most of the Third World Countries including India (infant mortality : 121 per 1000 births, as of 1981).
        
Family welfare  planning helps reduce the chances  of  high-risk pregnancies. Global evidences suggest that the risk is the  highest  if the mother is too young or too old, pregnancies too  many and too closely spaced; even when the infants survives the  pregnancies  occurring during the high-risk period may lead to  problems such as low birth-weight, nutritional deficiencies, frequency  episodes  of infectious diseases, slow  physical  growth  and development, etc.
        
In many developing countries 20-25% of the children die before  5 years  of  age.  Many of these deaths are  preventable  with  the available  health technology, but the social  circumstances,  including  traditional cultural norms, act as a deterrent.  Medical and  social  factors interact in generating the  deterrents  and, therefore, the intervention measures must incorporate such interactions.  Some of these interacting factors are age at  marriage, birth  spacing,  breast  feeding, age at  first  birth,  mother's education, mother's participation in labour force, mother's  role in  decision  making and contraceptive  knowledge,  attitude  and practice, etc.

The objective of study is to investigate into the determinants of fertility  and mortality, especially the latter, on which  hardly any urban Indian data exist, adopting a biosocial strategy, i.e., using the approaches of both biomedical and social sciences.  Two minor objectives which follows from the major one are, first,  to obtain a base line information on health conditions of the general population, and second, to enquire how existing living  conditions and social behavioral patterns in the immediate surrounding act as determinants of, particularly, maternal and child  health, including  mortality  of both. Identification  of  major  social, economic  and other possible determinants of maternal  and  child health may lead to formulation of more effective community health planning.

The study was conducted among Hindus and Muslims in slum areas of Calcutta city.

Thrust  areas  :     

(a) Which biomedical  and/or  social  factor(s) determine fertility, mortality and maternal and child health most effectively?  

(b) Do the factor(s) varies(y) in relation to  economic and/or social group affiliation?

(c) How do biomedical  and social  factors interact in determining the traits  mentioned  in (a)?


Outcome :    

The general outcome of the study shows that there is a  constriction at the base of the population pyramid, which may indicate  a recent drop in fertility due perhaps to the acceptance of  family planning  methods.  Polygynous  marriage are  almost  absent  and monogamy  is the usual practice among both the religious  groups. One or two sporadic case(s) of consanguineous marriages are found among the Muslims.

The Hindu  females show somewhat late marriage compared  to  the Muslims.
        
The  Muslims females are educationally backward compared  to  the Hindus  and they start childbearing earlier than the Hindus.  The percentage  of nulliparous women is higher among the Hindus  than the  Muslims. The Muslims have higher fertility compared  to  the Hindus.  Total Fertility Rate, Completed Family size as  well  as Sibship size are higher among the Muslims compared to the  Hindus Spacing  is  too  closed among the younger mothers  of  both  the religious  group but the gap increases from the 30-34  years  age onwards.

Mortality  Rate  is  higher in all the  stages  (neonatal,  post-neonatal, childhood) in the Muslims compared to the Hindus as  is the case with fertility.

From  the Life Table analyses, it appears that the  age  specific mortality is higher among the Muslims than the Hindus.

Expectation  of   life at birth as well as  subsequent  ages  are higher among the Hindus compared  to the Muslims.
        
Both  the average number of live birth and infant  death  reduces with  the  rise in literacy level in both the  groups  especially among the Hindus.
        
The average number of live birth and infant death decreases  with the  rise  of  age at marriage. The results also  show  that  the marriage duration affects both fertility and mortality.
        
Only  20 percent of live births are delivered at home  among  the illiterate  section of the Hindus. Home delivery is  much  higher among the Muslims compared to the Hindus. Institutional  delivery among the Hindus increases with advancing education (80% to 100%, respectively),  whereas the corresponding figures among the  Muslims are 42.9 to 66.7 percent, respectively.

The  younger mothers of both the communities prefer small  family size  but the attitude varies between the two groups,  e.g.,  the Hindus prefer not more than two children whereas the Muslims want at least three. The family size rises with the increase of age of the  mother  in both the communities. The results show  that  the women,  on  average, have already borne more children  than  they preferred to have.
        
Among  the  Hindus, acceptance of modern F.P. methods  is  higher even among the illiterate section. The acceptance of modern  F.P. method among the Muslims rises with increasing literacy level but the overall rate is lower than the Hindus.
        
The  air-borne,  water-borne and other infectious  diseases  like measles,  chicken pox, dysentery, malaria, tuberculosis,  pneumonia,  liver diseases are common in both the communities at  post-neonatal  stage (1 - ó 5 yrs.). Such diseases are sometimes  lead to death at neonatal stage in both the communities.
        
The allopathic treatment is the usual practice but occasionally homoeopathic  treatment is also sought. Supernatural  belief  regarding disease and folk treatment are also found among both  the groups especially among the older folks.
        
About 20 percent of the children are solely breastfed upto twenty five months among both the religious groups. supplementary  foods are initiated from six to thirteen or above months.

The dwelling of both the religious groups, is by and large, similar and are enjoying similar civic amenities.
        
The slum dwelling Hindu women are engaged in out-of-home job  (as maidservant, attendant at  nursing home). On the other hand,  the Muslim women are not permitted to go outside their own  territory and some of them are engaged in making cardboard box, bidi,  etc. at home.
        
The status of women is low in the Muslim society and  practically they  have no role in decision making even in the matter  of  her own reproductive life.
        
The health seeking behaviour pattern is different and  which  in turn lead to mortality differential between the two communities.
        
The higher fertility among the Muslims may be due to lower  survival prospect (due to higher mortality), a strong son preference and  perceived threat to existence of a minority  community;  and the  higher  mortality  among the Muslims may  be  due  to  lower (female)  literacy  rate,  poor standard of living  due  to  poor economic  condition, lower age at marriage, higher rate of  "high risk pregnancy" due to lower acceptance of family planning  methods,  lower  awareness about the importance of  immunization  and health care.

In general, both the Communities are reluctant  about  utilizing the available health infrastructural facilities (like  government hospital) due to the negligence and lack of sympathy on the  part of  the government doctors and the unavailability of medicine  in the hospital. It is therefore needed to probe the health  seeking  behaviour (health culture) thoroughly and intensively.

So, there  is a clear influence of cultural  factors  associated with religion on the mortality and fertility differentials  among the Hindus and the Muslims slum dwellers of Calcutta city.
