NLM5008 Nutrition, Lifestyle, and Intergenerational Impacts

How NLM5008 is assessed

The five published weights total 100%, and the curriculum document repeats the same split. The course materials reviewed here state no hurdle or minimum-mark condition for any component, so none is claimed in either direction; confirm the position on Canvas. Two details differ between documents: the course introduction describes the mid-term as 1.5 hours with multiple-choice and short-answer questions, while the later recess-week announcement gives two hours and 50 multiple-choice questions, and the curriculum document sets the mid-term scope at Weeks 1 to 6 where the other documents say Weeks 1 to 5. The curriculum form places the Final Presentation's 30% on its final examination line; the teaching calendar schedules a group presentation, not a written paper, in Week 13.

What NLM5008 covers

Eleven chapters follow the lecture schedule: the developmental origins hypothesis and its mechanisms, the famines and cohorts that test it, maternal and paternal factors before and during pregnancy, the environment, and the family plan the presentations ask for.

The course description frames it as a walk through each critical life phase, showing how nutrition and lifestyle shape the health of men, women and their children, with the emphasis on promotion strategies that break cycles of poor health.

How the thirteen weeks build

The first week states the hypothesis, traces it to a 1986 study that compared infant deaths and adult heart disease across areas of England and Wales, and introduces epigenetics as the mechanism that might carry early exposures forward.

The same week tests the idea on two famines, where the timing of hunger during pregnancy left different traces in adult health. The second week turns to the cohorts that follow grandparents, parents and children together. Weeks 3 to 5 cover maternal and paternal nutrition and lifestyle before conception, during pregnancy and after birth, including physical activity, sleep, smoking and blood pressure.

After the recess week come environmental exposures, three guest lectures and the two group presentations.

The skill the quizzes keep testing

Most of the studies in this course are observational, and the pre-lecture quizzes are built from the readings.

The recurring skill is to read a study in the right order: what design it used, who was studied and when, which direction the result runs, and what the design cannot show. A famine is a natural experiment rather than a trial, a mouse is not a father, and a ratio below one is a reduction.

The chapters work at least one study through in full so you can see how a careful reading sounds.

How the grade is made up

Five components carry the grade. Lecture attendance is worth 10%. Five pre-lecture quizzes at 4% each make up 20%, with the best four counted. A pen and paper mid-term in Week 7 is worth 20%.

A case discussion group presentation in Week 11 is worth 20%, and a final group presentation in Week 13 is worth 30%, the largest single piece.

Half of the grade therefore comes from two presentations built around a family case that runs from preconception to early childhood.

Where the published documents disagree

The course introduction describes the mid-term as a 1.5-hour paper with multiple-choice and short-answer questions; the later recess-week announcement gives a two-hour window, closed-book, with 50 multiple-choice questions.

The introduction deck and both timetables limit the mid-term to the Weeks 1 to 5 lecture material, while the curriculum document says Weeks 1 to 6; the Canvas folder for the Week 6 guest lecture is marked as not tested. This guide follows the later, more specific notices and flags the differences where they matter.

Key terms

DOHaD

The Developmental Origins of Health and Disease: the hypothesis that exposures in sensitive periods before and after birth can permanently shape later health.

Epigenetics

The study of how one genotype gives rise to different phenotypes through changes in which genes are read, without changing the DNA sequence.

DNA Methylation

The addition of chemical tags to DNA that usually quiets the gene nearby; the process behind the Agouti mouse results.

Natural Experiment

An exposure imposed by events rather than researchers, such as a famine, whose sharp timing lets exposed and unexposed groups be compared.

Intergenerational Cohort

A study that follows at least two linked generations, labelled F0, F1 and F2, to relate one generation's exposure to another's health.

POHaD

Paternal Origins of Health and Disease: the extension asking how a father's exposures before conception affect his children.

Hazard Ratio

The ratio of the rate of an outcome in an exposed group to the rate in a comparison group; above 1 means a higher rate.

Funnel Plot

A scatter of study results against study size used in a meta-analysis to look for asymmetry that suggests publication bias.

Metabolic Equivalent

A unit of physical activity intensity in which 1 MET is the energy used at rest; moderate activity is 3 to 5.9 METs.

NLM5008 FAQ

Questions students ask in each NLM5008 chapter

Why is the 1986 study called ecological?

Its data were rates for 212 local authority areas, not measurements on people. It linked the infant mortality of each area in 1921 to 1925 with that area's heart disease mortality in 1968 to 1978, so it can describe places but cannot say that any individual infant became a sick adult. Chapter 01 · Developmental Origins of Health and Disease

Why are identical twins useful for studying epigenetics?

They share the same genes, so differences between them in phenotype point to the environment. The lecture describes monozygotic twins as a more rigorous framework for studying environmental effects than general population studies, where genetic and environmental differences are mixed. Chapter 02 · Epigenetic Mechanisms and Early-Life Exposures

What makes the Dutch famine a natural experiment?

Hunger was imposed by war on a previously well-nourished population, in a defined area, with an abrupt start and end, and rations were recorded. Birth dates therefore tell researchers which trimester each person was exposed in, without anyone assigning hunger deliberately. Chapter 03 · The Dutch and Chinese Famines as Natural Experiments

Which intergenerational design is most common?

The birth cohort extended to three generations, with fifteen of the twenty-eight cohorts in the 2024 scoping review. It starts with pregnancies and babies and later recruits the babies' own children, which suits questions about exposures in pregnancy. Chapter 04 · Intergenerational Cohorts Around the World

Does physical activity help or harm female fertility?

Both, depending on dose and energy balance. Pooled cohort evidence links moderate activity to a lower infertility risk than low activity, while very intense activity without enough food can disrupt hormones and ovulation. The reading treats activity and diet as one system. Chapter 05 · Women's Preconception Health and Fertility

How can a father's stress affect offspring in the mouse study?

Partly through the mother. Females mated with stressed males changed their own pregnancy weight gain and nursing, and the paper concludes the offspring effects were partially mediated via mothers, so the route is not sperm alone. Chapter 06 · Paternal Diet and Lifestyle Before Conception

Did the Mediterranean diet in pregnancy cause lower child adiposity?

The study cannot say. It found that higher scores were associated with lower child BMI z-score, waist and skin-folds in two pooled cohorts, but the design is observational, so the authors call for intervention trials to test whether the diet itself is responsible. Chapter 07 · Diet in Pregnancy and the Postpartum Period

What does a funnel plot show?

Each study's estimate against its size or precision. Large studies cluster near the pooled value and small ones scatter more widely beneath them; an asymmetric shape, with small studies missing on one side, suggests publication bias. Chapter 08 · Non-Dietary Factors and Reading Pooled Evidence

Why rank dietary patterns above single nutrients?

Because foods are eaten together and interact. Eating more of one food displaces another, and nutrients can interfere with each other, as zinc does with copper absorption. A pattern captures those combined effects, which a single nutrient cannot. Chapter 09 · Dietary Patterns and Meal Timing in Metabolic Health

What did the Taipei greenness study find?

More residential greenness in mid-pregnancy was associated with fewer attention problems at ages two and three on a mother-rated behaviour checklist. Greenness after birth was associated only with attention, not with other behaviour scales. Chapter 10 · Environmental Exposures Before and During Pregnancy

What does the final presentation ask groups to do?

Use what the course has taught to propose lifestyle changes, each backed by evidence, for one family whose story runs from before conception to early childhood, with the aim of improving health across the generations in that family. Chapter 11 · Designing Intergenerational Health Promotion

How to prepare for the assessments

After each lecture, write one line for every study it cites in the same order: design, population, exposure window, direction of the result, and one thing the design cannot show. Those lines are exactly what the quizzes test, and by Week 11 they become the evidence map your group builds its family plan from.
