Abstract

Objective

To assess the impact of an intervention modifying dietary habits for the prevention of anaemia in rural India.

Design

Intervention study with data on anthropometric (weight, height) measurements, Hb and diet pattern. As per the cut-off for Hb in the government programme, women with Hb <11 g/dl had to be given Fe tablets and formed the supplemented group while those with Hb > 11 g/dl formed the non-supplemented group.

Settings

Three villages near Pune city, Maharashtra, India.

Subjects

Rural non-pregnant women (n 317) of childbearing age (15–35 years).

Results

After 1 year of intervention, mean Hb increased (from 10·94 (sd 1·22) g/dl to 11·59 (sd 1·11) g/dl) significantly (P < 0·01) with a consequent reduction in the prevalence of anaemia (from 82·0 % to 55·4 %) as well as Fe-deficiency anaemia (from 30·3 % to 10·8 %). Gain in Hb was inversely associated with the initial level of Hb. Significant gain in Hb (0·57 g/dl) was observed among women attending >50 % of the meetings or repeating >50 % of the recipes at home (0·45 g/dl) in the non-supplemented group and was smaller than that observed in the supplemented group. Consumption of green leafy vegetables more than twice weekly increased substantially from 44·7 % to 60·6 %, as did consumption of seasonal fruits. Logistic regression showed that women with lower participation in the intervention had three times higher risk (OR = 3·08; 95 % CI 1·04, 9·13; P = 0·04) for no gain in Hb compared with those having high participation.

Conclusions

Developing action programmes for improving nutritional awareness to enhance the consumption of Fe-rich foods has great potential for preventing anaemia in rural India.

Fe-deficiency anaemia is a common nutritional problem, particularly for women of reproductive age in developing countries. Fe deficiency continues to be the leading single nutrient deficiency in the world, affecting more than two billion persons despite considerable efforts to decrease its prevalence over the past three decades( 1 ). In India, its prevalence in women has been reported to be in the range of 33 to 89 % in different studies( Reference Seshadri, Sharma and Ra 2 Reference Sarin 8 ) covering pregnant or non-pregnant women of childbearing age. Although the National Nutritional Anaemia Prophylaxis Program has been in operation since 1970, under which Fe + folic acid tablets are distributed to pregnant women, the evaluation of the programme conducted during 1985–86 showed no impact on the prevalence of anaemia( 4 ).

In practice, the efficiency of large-scale programmes has been limited for various reasons such as poor access to prenatal care, insufficient and inconsistent supply of Fe supplements, insufficient counselling on the need for and the benefits of Fe supplements and an unwillingness by pregnant women to take Fe supplements( Reference Toteja and Singh 9 ). Besides, malarial infections and worm infestations, known factors associated with anaemia, are commonly prevalent in rural areas. Nevertheless, the importance of dietary deficiencies cannot be overlooked as Fe-deficiency anaemia resulting from inadequate intake and low absorption of dietary Fe has been shown to be the most common cause of anaemia in India( Reference Toteja and Singh 9 , Reference Rao 10 ).

The public health approach of Fe fortification of food has had success in the USA in reducing the prevalence of anaemia in women of reproductive age( Reference Beard 11 ), but such approaches – although feasible in developed countries – are impractical in economically poor countries. Therefore, an alternative to supplementation is to increase the consumption of micronutrient-rich foods. In a study from rural central Mexico it was reported that better Fe status was associated with higher intakes of non-haem Fe and foods that contain ascorbic acid( Reference Backstrand, Allen and Black 12 ). Similarly, in Indonesia social marketing played a critical role in increasing the consumption of vitamin A from plant and animal sources( Reference De Pee and Bloem 13 ). Moreover, single micronutrient deficiencies are rare and it is likely that Fe deficiency in anaemic individuals is compounded by multiple micronutrient deficiencies( Reference Ahmed, Khan and Akhtaruzzaman 14 ). Thus, a multi-pronged dietary strategy using a feasible educational programme combined with identifying and promoting the best choices of Fe-rich foods is required to increase the consumption of animal sources of Fe and of vegetables with Fe-absorption enhancers such as vitamin C( Reference Amani and Soflaei 15 ). More research is urgently needed to evaluate dietary approaches, especially those using vegetables for combating Fe deficiency in vegetarian populations. The present study aimed to examine the impact of dietary diversification attempted through live demonstrations of Fe-rich recipes for improving the dietary Fe status of non-pregnant women of childbearing age from rural India.

Materials and methods

Three villages (Dhamari, Hivare and Pimple), situated within 45 km from Pune district, Maharashtra, India, were considered for the study. The villages represented the typical Indian village and were largely homogeneous. For the present interventional study, a census was done on all houses in these villages to get a list of eligible women from each house and the women were enrolled in the study only after their oral consent. The census covered a total population of 8300 individuals and the initial number of eligible (15–35 years) non-pregnant women was 317. Most women were from a subsistence farming community with marginal land holdings and were residing in an extended family with their in-laws. Here, we present the data on non-pregnant women from the first year of the study.

Personal information

Each woman enrolled in the study was interviewed by a nutritionist in a house-to-house visit, using a field-tested structured questionnaire for getting personal information, measuring anthropometric variables and obtaining obstetric history. Personal information comprised the woman's current age, age at menarche, age at marriage, education, type of income-generating work, if engaged in any work other than household work, etc. The woman's weight was measured (to the nearest 200 g) using a portable digital weighing balance (ATCO, India) and her height was measured (to the nearest 0·1 cm) using a stadiometer.

Dietary assessment

An FFQ, developed in an earlier study( Reference Rao, Yajnik and Kanade 16 ) for rural mothers from villages in the same area, was used for assessing each woman's habitual dietary pattern. Nevertheless, the FFQ was field-tested before using in the present study but no changes were required. During follow-up, the FFQ was repeated every 6 months.

Hb estimation

A trained technician accompanying the research team drew a venous blood sample (2 ml) from each woman into an EDTA tube; the tubes were transported to a pathological laboratory in Pune, taking proper precautions. The samples were immediately analysed for Hb by the cyanmethaemoglobin method and peripheral smear examinations (i.e. colour, size and shape) were conducted. A blood smear was prepared, stained with Leishman stain and covered for 2 min. Then alkaline buffer solution was added and was kept for 10 min. The smear was washed with running distilled water, dried and observed under a microscope to classify nutritional and Fe-deficiency anaemia( Reference Dacie and Lewis 17 ). Normocytic normochromic cells were considered as normal, while normocytic hypochromic with the presence of macrocytic cells was considered as nutritional anaemia indicative of vitamin deficiency. Additionally, hypochromic normocytic with anisocytosis was also considered as nutritional anaemia. Only hypochromic microcytic with anisocytosis/pikilocytosis was considered indicative of Fe-deficiency anaemia. Peripheral blood examination also checked for the presence of malarial parasites.

Composition of research team and their roles

The research team, comprising a lady doctor, two nutritionists and a technician, visited each of the study villages once per fortnight. The role of the lady doctor was to conduct informal meetings for imparting health-related information, while the nutritionist talked about nutrition-related issues. The nutritionist was also responsible for developing and standardising Fe-rich recipes from locally available green leafy vegetables (GLV) at the nutrition laboratory in Pune and provided training to the community health workers (CHW) for keeping various types of qualitative and quantitative records related to the intervention. The technician was responsible for collecting the blood samples from the women.

Developing Fe-rich recipes from green leafy vegetables

Several points were considered in developing and standardising the Fe-rich recipes. First, emphasis was given to using locally available, low-cost ingredients in developing the recipes. Second, along with Fe, an attempt was made to increase the content of other important micronutrients like folic acid, vitamin C, β-carotene and Ca, which are known to promote fetal growth. Third, it was essential to ensure that the recipes were easy to prepare, less time consuming and palatable, and could provide a variety of options for substitution. Finally, it was necessary that these recipes were not new dishes but were developed by incorporating GLV into the women's staple foods like roti, dhal, etc. for increasing their Fe intake substantially.

Salient features of Fe-rich recipes

The habitual diet of the women consisted of a roti (wheat or sorghum bread), a pulse or legume or vegetable curry, green chilli chutney and rice. It lacked salad, curd or buttermilk and GLV, and thus lacked variety. The recipes developed were essentially modifications of the commonly consumed recipes in rural areas. Thus, roti – a major food in their diet – was modified to spicy roti (thalipith/paratha) with the addition of GLV in the dough. Similarly, rice was modified with spring onion and cabbage leaves. Dhal preparation, another integral part of the diet, was developed with GLV and in informal meetings use of lemon in dhal during meals was recommended for increasing Fe absorption.

Among the side dishes, dry besan (pithale, made from gram flour) was most frequently consumed in all rural families. Addition of GLV to it thus ensured increased protein intake as well as increased frequency of GLV consumption. Green chilli chutney, which was part and parcel of their daily diet, was enriched with micronutrients by adding lot of coriander or mint and lemon. Salad was never a part of the rural diet but was developed for its maximum benefit (nutrient security), as losses of vitamins due to cooking are totally prevented. Use of lemon juice in its dressing was insisted upon to increase Fe bioavailability.

GLV soup was not only rich in vitamins but also had a texture suitable for young and old alike. Vegetable rolls (mutkule or tikki) developed using fenugreek or spinach was never known to rural women and became a popular dish.

Recipes were developed from thirteen commonly consumed GLV in this community, such as amaranth, spring onion (onion stalk), shepu, chakwat (bathua leaves), kardai (safflower leaves), mula (radish leaves), spinach, fenugreek leaves, ambat chukka, etc., used singly or in combinations to maximise Fe content.

Community health workers

Young married girls from the local community, who had schooling up to 10th standard and a good rapport with rural women, were appointed as CHW for each village. Duties of the CHW involved motivating women for attending meetings and for giving blood samples, visiting each women a couple of times in a week to inform about the date and time of meetings, keeping attendance records of the meetings, distributing the blood reports, and occasionally accompanying the technician on house visits for collecting a blood sample from women not attending the meetings. They maintained the record of women attending the meetings and also of women who were actually doing the recipes in their homes, during their weekly visits. Finally, they also repeated the demonstrations of the recipes to small groups of five to ten women, especially for those who could not come for the regular meetings.

Intervention

Although the major intervention was developing Fe-rich recipes from commonly consumed GLV and organising their live demonstration regularly, this was facilitated through informal meetings organised once per month. All women were initially given a deworming tablet under medical supervision. Health-related issues such as symptoms and adverse effects of anaemia during pregnancy, increased requirements during pregnancy, importance of macro- and micronutrients in relation to birth size and anaemia, etc. were discussed in the local dialect by a lady doctor during the meetings. Similarly, the nutritionist discussed the sources of micronutrients, the benefits of eating raw salads, the importance of seasonal fruits like guava, tamrind and zizapus which are rich sources of vitamin C, etc. A poster in the size of a calendar, showing pictures and messages in the local language related to causal factors, symptoms and implications of anaemia, was prepared and given to each enrolled woman.

Live demonstrations of Fe-rich recipes from green leafy vegetables

In the beginning, the nutritionist explained the importance of the different ingredients used in the recipes to be demonstrated and also the possible substitutes for these ingredients. During each meeting, three or four recipes from a particular GLV were demonstrated. After the demonstration all women were then given a sample of these recipes prepared, along with a roti, for actual tasting of the recipes demonstrated. The activity of live demonstrations of recipes became popular as cooking is dear to rural women and it made a significant impact as ‘seeing is believing’. At the end, each woman was given (free of cost) a bunch of the GLV so that they would repeat at least one of the recipes demonstrated for their evening meal. The description of the recipe in a local dialect was prepared and copies were distributed immediately. Additional copies were kept with CHW so that women who could not attend the meeting would get it from CHW. Similarly, a poster in the form of a wall calendar, summarising various types of recipes that can be prepared from GLV, was prepared with colourful pictures of the recipes and distributed to all women in the study. In total fifty Fe-rich recipes using commonly consumed GLV were demonstrated and demonstrations were repeated by CHW in small groups of women.

As per the cut-off for Hb in the government programme, Fe tablets (60 mg of elemental Fe) were given to women with Hb <11 g/dl, who formed the supplemented group; while those with Hb > 11 g/dl formed the non-supplemented group. However, the analysis was done separately for supplemented and non-supplemented groups for examining the impact of the intervention involving dietary diversification.

Monitoring interventional activities

Two important aspects of the intervention were attending the meeting for gaining nutrition- and health-related knowledge especially focused on pregnancy and learning the Fe-rich recipes from live demonstrations. A separate notebook was maintained with CHW for keeping records of the interventional activities. For each meeting they recorded the names of the women attending the meeting. The second important aspect was to know whether the women were repeating the recipes at home. The CHW visited each woman weekly; to facilitate this, the total eligible women in a village were divided into six groups and each group was visited on a fixed day of the week from Monday to Saturday, thus covering the entire sample in a week's time. During their weekly visits, CHW recorded which recipes out of those demonstrated were actually done in the week following the meeting by each enrolled woman.

Statistical methods

Differences in mean gain in Hb between the initial and final rounds (after 1 year) were tested using the paired t test. Linearity of trend in mean gain in Hb by interventional activity group was tested using one-way ANOVA. The proportions of women with Fe-deficiency anaemia in various categories of nutritional status (using anthropometric measurements) were tested for trend using the Z test. Multiple logistic regression analysis was carried out for computing odds ratios for risk of no gain in Hb associated with various factors. All analyses were conducted using the statistical software package SPSS/PC+ for Windows version 11·0. Ethical permission was obtained from Agharkar Research Institute Ethical Committee for Human Studies before implementing the project.

Results

Distribution of Hb and prevalence of anaemia

Distribution of Hb in the initial and final rounds for non-pregnant women of childbearing age is shown in Fig. 1. The shift of the Hb distribution to the right after 1 year clearly indicates improvement in the Hb status of women. The prevalence of severe anaemia (Hb<10 g/dl) reduced significantly (P < 0·001) from 19·2 % in the initial year to 7·1 % at the end of 1 year. There was also a significant (P < 0·001) rise from 18·0 % to 44·6 % in the proportion of women with normal (>12 g/dl) Hb levels. The prevalence of anaemia was thus reduced significantly (P < 0·01) at the end of the first year (from 82·0 % to 55·4 %) and the same was also true for the prevalence of Fe-deficiency anaemia, which decreased from 30·3 % in the initial year to 10·8 % at the end of 1 year (P < 0·01). Overall gain in Hb over the period of 1 year for the entire group was 0·66 g/dl (Table 1). Women who were given Fe tablets showed a significant (P < 0·001) improvement in Hb (1·36 g/dl), while in the non-supplemented group improvement in Hb (0·18 g/dl) was marginally significant (P = 0·06).

The improvement in mean Hb was inversely associated with the initial level of Hb, showing the highest gain of 2·0 (sd 1·66) g/dl among women with Hb below 9·0 g/dl (Fig. 2). Furthermore, Hb gain was examined by various maternal characteristics (Table 2). Gain in mean Hb was significant (P < 0·001) in all categories of pre-pregnant weight but appeared to be higher in the lowest weight category and decreased with increase in maternal weight. Similarly, gain in mean Hb was highest in short mothers (<150 cm), among those who had high parity (>1) and among older mothers (>25 years), indicating greater benefits to the undernourished mothers.

Impact of the intervention on Hb status

In order to examine the effect of the intervention, supplemented and non-supplemented groups are considered separately. Informal meetings preceded the live demonstrations for discussion of Fe-rich recipes by the nutritionist. Women were classified by their participation levels in attending these meetings. It was equally important to repeat these recipes at home frequently. It can be seen (Table 3) that in the supplemented group, even with the lowest level of participation (<25 % attendance) in informal meetings, the gain in Hb was 1·20 g/dl but increased to 1·87 g/dl in the case of women having higher participation (>50 % attendance), indicating the benefits of participation. In the non-supplemented group, although the magnitude of gain was much smaller, an increasing trend (P < 0·01) in Hb gain was seen with increasing attendance indicating the effect of this interventional activity. In particular, women attending more than 50 % of the meetings in the non-supplemented group showed significant gain in Hb (0·57 g/dl) that was about one-third of the gain observed in the supplemented group.

*P < 0·01 for gain in Hb over a period of 1 year using the paired t test.

†Linearity of trend in mean gain in Hb using one-way ANOVA.

With regard to the main intervention in the study, repeating the demonstrated recipes at home was essential. It can be seen (Table 3) that not only was the gain in Hb significant for all levels of participation, but it also showed a significant (P < 0·01) increasing trend with the increase in level of participation. Thus supplemented women who repeated more than 50 % of the recipes at home showed almost double the gain in Hb (1·80 g/dl) compared with those who could repeat only less than 25 % of the recipes (0·91 g/dl). Once again among the non-supplemented group, although the magnitude of the gain was low, an increasing trend (P < 0·01) in Hb gain was seen with increasing participation. In particular, the gain in Hb (0·45 g/dl) among non-supplemented women having the highest participation in this activity was about 25 % of that observed in the supplemented group. Thus, in the non-supplemented group, the magnitude of gain in Hb was significant only for the highest level of participation and showed an independent effect.

Effect of the intervention on consumption of green leafy vegetables

Data from the FFQ were analysed to see whether the interventional activities had an impact on actual consumption of micronutrient-rich foods, especially GLV and seasonally available fruits. It can be seen (Fig. 3) that the frequency of GLV consumption less than once weekly decreased from 19·7 % to 5·6 %, while that of GLV consumption more than twice weekly increased substantially from 44·7 % to 60·6 % during the period of 1 year in the supplemented group. Similar trends were also seen in the non-supplemented group. A significant change was also observed in the consumption of locally available seasonal fruits during the period of 1 year, in both supplemented and non-supplemented groups (Fig. 3). Thus the observations show that the intervention undertaken in the present study improved the actual consumption of GLV and fruits which provide not only Fe but combinations of micronutrients, resulting in the improved Hb status of the study women.

Multiple logistic regression analysis was done to examine the risk of no improvement in Hb over a period of 1 year and to observe the odds for various confounding factors (Table 4). Among all maternal parameters (weight, height, parity and age) considered, only in the case of maternal age was the risk of no improvement in Hb seen to be marginally significant (P = 0·06). However, both meeting attendance (P = 0·04) and repeating at home the recipes demonstrated in the meetings (P = 0·03) showed significant associations with gain in Hb. Women with lower attendance at meetings (<50 %) as well as those repeating recipes at home less frequently (<50 %) showed about three times higher risk for no gain in Hb compared with their counterparts with higher attendance (≥50 %) or higher frequency of repeating recipes (≥50 %). Thus the interventional activities showed independent significant effects on Hb. After adjusting for initial Hb, the significance and the odds ratios increased in the case of social action parameters but disappeared in the case of maternal parameters, thus highlighting the importance of the interventional activities taken in the present study.

Discussion

Fe-deficiency anaemia resulting from inadequate intake and low absorption of dietary Fe is the most common form of anaemia in India( Reference Sarin 8 , Reference Toteja and Singh 9 ). The National Nutritional Anaemia Control Program distributes Fe + folic acid tablets to pregnant women but does not cover non-pregnant women of childbearing age. The existing programme has repeatedly been shown to be ineffective in reducing the prevalence of anaemia( Reference Sood, Ramachandran and Mathur 3 , 4 , Reference Ramachandran 18 ), the reasons mentioned being poor access to prenatal care, insufficient and inconsistent supply of Fe supplements, insufficient counselling on the need for and the benefits of Fe supplements and, more importantly, an unwillingness by pregnant women to take Fe supplements( Reference Bothwell 19 ). As Fe deficiency is likely to be compounded by multiple micronutrient deficiencies, simultaneous efforts for increasing the consumption of micronutrient-rich vegetarian foods are also essential. Clearly, GLV form a food group of potential interest as they are a rich and cheap source of all vitamins and minerals, but more research is urgently needed for investigating the effects of dietary diversification in poor populations. Our study shows that addressing rural women through social actions, namely live demonstration of Fe-rich recipes for imparting nutritional knowledge and awareness, was able to reduce the prevalence of anaemia significantly.

Anaemia prevalence in the young, rural, non-pregnant women of childbearing age in our study was as large as 82 % and is in agreement with the prevalence of anaemia reported by studies from different states in India( Reference Saibaba, Mohan Ram and Ramana Rao 20 , Reference Kaur, Deshmukh and Garg 21 ). Despite this we found that the prevalence of Fe-deficiency anaemia was only 30·3 %, which indicates that other causes of anaemia may be prevalent in this population. Similar observations are reported in the case of Nepali women( Reference Chandyo, Strand and Ulvik 22 ). Hookworm infection and malaria are endemic in this population and region, and the majority of women may in fact have worm infestation. The larger the prevalence of anaemia, the more likely it is to have multiple causes and not be related solely to Fe deficiency. Although ferritin is commonly considered for detecting Fe deficiency, it is reported that there may be normal serum ferritin values despite a true Fe deficiency. In contrast, red-blood-cell morphology clearly revealed that Fe deficiency was largely confined to Hb levels below 11 g/dl, as 75 % of women with Hb below this level had Fe-deficiency anaemia. Thus red-blood-cell morphology, although not a robust method, is certainly a simple and cost-effective tool for identifying Fe-deficiency anaemia compared with other biochemical indicators.

At the end of 1 year the distribution of Hb showed a clear shift to the right when compared with the initial distribution and showed a significant reduction in the prevalence of anaemia. The gain in Hb was highest among women with low initial Hb (<9 g/dl) or who were undernourished. It is known that severely Fe-deficient individuals are more efficient in absorbing Fe and hence would derive more benefit than less Fe-deficient individuals( Reference Beard 11 ).

Although there is much evidence supporting the use of Fe supplementation in vulnerable groups, findings on the effects of nutrition education without supplementation and/or food fortification are lacking( Reference Amani and Soflaei 15 ). Nevertheless, the limited evidence available highlights potential benefits associated with nutrition education as an intervention for improving Fe status in Indian( Reference Kapur, Sharma and Agarwal 23 , Reference Garg and Kashyap 24 ) and other populations( Reference Kafatos, Vlachonikolis and Codrington 25 , Reference Creed-Kanashiro, Bartolini and Fukumoto 26 ). In fact, our approach of nutrition education was around a social action of live demonstration of Fe-rich recipes. We observed that the higher (>50 %) the participation in the interventional activities, the higher was the gain in Hb. Further, when education is transformed into action the benefits are likely to be more. Thus, women who repeated only 25–50 % of the recipes shown to them exhibited a greater gain in Hb (1·43 g/dl) than those who attended 25–50 % of the meetings (1·21 g/dl).

Dietary interventions have always resulted in relatively smaller change in Hb compared with Fe supplementation( Reference Patterson, Brown and Roberts 27 ). In our study too, improvement in Hb in the non-supplemented group was of smaller magnitude and was seen only in the highest level of participation compared with that in the group supplemented with Fe tablets. But this was not surprising as our intervention was addressing only behavioural change to improve the women's dietary status with regard to Fe. In fact, the small but significant improvements in the non-supplemented group assure that the intervention has effectively improved their knowledge with regard to consumption of GLV, which was also confirmed through food frequency data. Increase in the consumption of greens through nutrition education intervention has also been reported among women from Mysore( Reference Hemalatha and Prakash 28 ). We observed that the intervention undertaken in the present study improved the actual consumption of GLV and fruits significantly in both the supplemented and non-supplemented group. In particular, the proportion of women consuming GLV more than twice weekly increased from 36 % to 76 % among those attending meetings and those repeating the recipes at home more frequently, highlighting the impact of our intervention. The implication is that this will not only provide Fe but also combinations of micronutrients, resulting in the improved Hb status of the women in the study.

Finally, even after adjusting for other confounders, the multiple logistic regression analysis revealed the odds associated with no gain in Hb to be almost three times higher for women with low participation compared with those having high participation, thus emphasising the need for health education programmes for dietary diversification. It is believed that a lack of knowledge of the causes and consequences of nutritional deficiencies may influence food choices even in resource-poor populations( Reference Jones, Specio and Shrestha 29 ). Therefore, education to change knowledge, attitudes and household dietary practices may be required to effect positive changes in consumption and nutritional status. Food-based approaches to combat deficiencies of micronutrients deserve great attention because they are likely to be sustainable in the long term and will facilitate simultaneous increase in intake of all the micronutrients.

It is worthwhile to mention that the interventional activities offered several social impacts. First, the women learned many recipes and were certainly appreciated at home for offering variety in the diet. Second, although we measured Hb of women enrolled in the study, other family members must have benefited from the increased consumption of GLV owing to our intervention. Finally, the impact at the community level was that the village heads and multipurpose workers from neighbouring villages often attended the live demonstration meetings, thus spreading nutritional knowledge and awareness related to anaemia beyond the project villages.

Conclusion

Our observations indicate that the massive problem of anaemia in rural India, where ignorance is one of the root causes of the disease, needs education to change knowledge, attitudes and household dietary practices. Although technical solutions like fortification are possible for reducing Fe-deficiency anaemia at the population level, our study underscores the fact that nutrition education around social actions leading to dietary modification will bring about behavioural change resulting in sustainable improvement in the overall quality of the diet. It thus provides a feasible opportunity to attain high-priority health goals. Second, efforts to generate nutritional awareness through kitchen garden activity or arranging food exhibitions etc. may also be helpful. In Indonesia, social marketing played a critical role in increasing the consumption of vitamin A from plant and animal sources( Reference De Pee and Bloem 13 ). It is beyond doubt that not only operational research on how best to improve the existing Fe supplementation programme is needed( Reference Bentley and Griffiths 30 ), but also new and innovative strategies are required to improve the overall health and nutritional status of young rural mothers in India.
