The combined effects of seasonal labour inputs and food shortages on factors affecting the nutritional status of infants are considered in relation to the birth season which determines the age when children are most vulnerable to seasonality factors. Since the immunity of infants and small children varies with age, their birth season (and hence their age at different seasons of the year) greatly affects their survival chances.

Nutrition programmes hardly ever consider the seasonality of food supplies. Alone these are important, but here we consider the effects of food shortages coinciding with other seasonal variables such as seasonal labour inputs which create heavy energy demands especially for sections of the population already vulnerable to the effects of food maldistribution. These include pregnant and lactating females and preschool children especially in the 0–24 month age group.

Seasonal factors generally affect nutrition at all ages.

During periods of high temperatures, food is reduced considerably for several different physiological reasons, such as the elimination of excess energy. In contrast, during periods of low heat, food is increased to provide the body with energy to resist heat loss.

In the case of children, I think that the resistance of their bodies to environmental and seasonal changes is significantly lower compared to adults so the impact of seasonal changes have much clearer

Dear Dr. Neeran,

Please look over here: http://www.tandfonline.com/doi/abs/10.1080/00220387408421510?journalCode=fjds20

Sorry it's not my specialty. Best regards

I think the most important factor is the availability of the food itself.

Usually the food is abundant during the rainy and post rainy season

Availability of food is an important factor. With low production of vegetables and fruits, or with the persistent increase in the cost of transportation, the price of food increases. Accordingly, low resource families will change their consumption pattern both in quantity and quality.

thanks for all answers

Relevant to developing countries

1)maternal occupation; if a farmer/food stuffs seller ,who is gone from home for long periods, leaving child care to house help,older siblings, grandparents. This practice has a negative impact on nutritional status

2)seasonal variations in availability of foods that lower income families can afford, further increases food insecurity in such households

3)farmlands located in terrains that are flooded/swampy/otherwise difficult to access according to seasonal variations

4) poor agricultural yields due to marauders (an emerging problem in Nigeria)

5)seasonal variations in availability of certain low earner jobs such as farm hands, construction site load carriers ( mostly women in Nigeria)

6) many more ( if required)

thanks dr Dominica

In the preschool children the nutritional status declined in the lower socioeconomic group. These changes also coincided with a period of hard agricultural work, especially for women

Farming or planting season could contribute to poor care-giving practices (especially for mothers who are farmers), if they go to farm early in the morning and come back later in the day without making adequate food provision for their children. This could affect the dietary intake of children and subsequently leads to undernutrition in preschool children. However, recent studies have reported that child nutritional status varies across seasons and follows a seasonal pattern of childhood illness but not that of household food availability. Children were found to be less likely to be stunted and less likely to be underweight in the lean cropping season (September to February) compared to the post-harvest season (March to August) (Chikhungu and Madise, 2014). Children were found to consume more vitamin A-rich fruits and vitamin A rich dark green leafy vegetables during the rainy season than the dry season and also more vitamin A-rich deep yellow, orange and red vegetables during the dry season than during the rainy season (Abizari et al. 2017).
