Culture as a lens on health and illness

No individual chooses his culture, and this is the first thing a nurse must grasp. Culture is installed by enculturation — the lifelong process by which a person acquires the culture of his group, beginning in infancy and continuing through school, marriage and work. Much of the learning is explicit: a mother teaches a child to greet an elder with both hands, to eat with the right hand, to lower the eyes. A great deal more is implicit and absorbed by imitation, without any instruction at all. The French anthropologist Marcel Mauss called the results the “techniques of the body” in 1935: the learned, culturally specific ways of walking, sitting, squatting, eating, sleeping, washing, giving birth and expressing pain.

Nobody is born knowing how to squat for an hour or how to suppress a cry during an injection; these are trained capacities, and their absence is read by others as bad manners rather than as lack of practice. Pierre Bourdieu later named the durable, pre-reflective dispositions produced by this training habitus — the set of postures, tastes and immediate reactions that a group carries without being able to state it. His point was that habitus feels natural: it presents what has been learned as obvious. That is why a patient can find a hospital routine not merely inconvenient but wrong, and why telling him the rule will not change the feeling. Two clinical consequences follow.

First, because culture is largely unconscious, asking a patient to explain his culture yields a thin and flattering account; observing what he does in the waiting room, at the bedside and with his family is more reliable. Second, because culture is learned, it can be extended. A nurse can teach a family oral rehydration, a new sleep position for an infant or a different way of washing a wound without demanding that they abandon who they are, provided the new practice can be fitted into the habits of care they already have. Mauss’s insight — that the body is the first instrument of culture — is also a nursing insight: the body a patient brings to the ward has already been shaped by years of training.

Cultural relativism began as a research rule, not a moral programme. Franz Boas, a founder of American anthropology, argued from the 1890s that each culture must be understood in its own historical terms rather than ranked against a European standard, and he used that principle to attack the racial hierarchies then presented as science. His student Melville Herskovits gave the position its methodological force: a practice must be interpreted from inside the culture that produced it, because an outsider cannot see what it holds together or what it would cost to lose. The logical difficulty appeared at once. In 1947, as the United Nations drafted the Universal Declaration of Human Rights, the American Anthropological Association issued a statement warning that a declaration framed within one cultural tradition could not speak for all of them.

The debate that followed is the debate nursing still has, and it is resolved by separating relativism as method from relativism as ethics. Relativism as method commands the nurse to understand before judging: what does this practice do for the family, who benefits, what would replace it if it stopped, and what would abandoning it cost the patient in standing or marriage? Relativism as ethics asserts that no practice may ever be criticised, and that position is untenable because it abolishes the duty to protect. The harm test marks the boundary.

When a practice causes serious physical or psychological injury to a person who cannot consent — female genital mutilation, child marriage, severe dietary restriction in pregnancy, denial of emergency treatment to a child — the nurse acts to protect, drawing on clinical evidence, national law and human rights instruments, and does so openly rather than quietly. WHO documents female genital mutilation as a practice with no health benefits and a long list of immediate and long-term harms, recognises it as a violation of the human rights of girls and women, and urges health workers never to perform it — including in its “medicalised” form. Acting on that evidence is not ethnocentrism, because ethnocentrism judges without understanding. Here the nurse has understood the practice, can state what the family believes it achieves, and still refuses it, explaining the harm and protecting the child.

The cost of confusing the labels is easiest to see in what the confusion hides. Human genetic variation is distributed gradually across geography, with far more variation inside any named group than between groups, so no sharp line separates human populations; the categories inherited from colonial science were constructed to justify hierarchy. UNESCO issued a statement on race in 1950 precisely to make this point, and the discipline has treated race as a social fact — with real effects on health — ever since. Ethnicity is a claim of shared ancestry, language or history, usually self-ascribed. Nationality is legal membership of a state.

Two clinical consequences follow. The first is essentialism: treating a person as a specimen of a category, so that “the Fulani family” or “the village patient” is expected to behave in a fixed way. Essentialism fails twice. It hides the differences inside the group — a wealthy urban household and a poor rural one may share an ethnicity and almost no habits — and it manufactures a cultural explanation where the real cause is material. The second consequence is that this mislabelling hides structure. Paul Farmer called the arrangement of poverty, distance, unpaid labour and unequal access that damages health without any identifiable aggressor structural violence, and his point was that it is invisible precisely because it produces no villain and no single event.

A family that cannot return for a follow-up visit is more often constrained by the fare, the harvest calendar or a wage that is paid late than by a belief. Jonathan Metzl and Helena Hansen proposed structural competency in 2014 as the correction: clinicians should read upstream conditions — housing, transport, wages, policing, food supply — with the same attention they give to beliefs and behaviour. The practical rule for the nurse is therefore twofold. Ask about this patient as an individual before generalising, and treat every cultural claim as a hypothesis to be checked in conversation rather than a fact to be assumed from a name, a language or a file note written by someone else.
