Convincing evidence exists for a beneficial effect of physical activity (PA) on health and well-being for elderly women. Nevertheless, many women in Germany are insufficiently physically active. Activity promotion programmes should target women in particular need. Thus, we examined subject-related determinants of PA for postmenopausal women in Germany.

Associations of sociodemographic, anthropometric, lifestyle and health-related factors with activity since the age of 50 years were assessed with multiple linear and logistic regression models, regarding overall leisure-time PA (LPA) in metabolic equivalent hours per week, engagement in sports (ever v. never), cycling (yes v. no) and walking (≥3·5 v. <3·5 h/week).

All controls from a population-based case–control study carried out in 2002–2005 in Germany (MARIE study).

A total of 6569 postmenopausal women.

We found significant associations of overall LPA, sports, cycling and walking in postmenopausal years with several characteristics, among others: obese v. normal BMI (adjusted OR: ORsports = 0·73; ORcycling = 0·60; ORwalking = 0·63), tall v. short (ORsports = 1·49), worker v. medium employee (ORsports = 0·47), working full time v. unemployed/retired (ORsports = 0·80; ORwalking = 0·56), current v. non-smoker (ORsports = 0·62; ORcycling = 0·62; ORwalking = 0·82), non-German nationality (ORsports = 0·58; ORcycling = 0·41). Parity seemed more relevant than marital status for sports or cycling activity. Further, CVD, hypertension and diabetes were significantly associated with lower activity (ORsports = 0·77, 0·79 and 0·80; ORcycling = 0·80, 0·75 and 0·85, respectively).

Our results suggest potential target groups for promoting sports, cycling or walking activity. Postmenopausal women with chronic diseases may need to be stronger encouraged by their physicians to engage in adequate PA for the management of their diseases.

The present study aimed to investigate weight retention and body composition in the postpartum period between adolescent girls and older women.

A prospective cohort study. Anthropometry and skinfold thickness measurements were performed at the first antenatal visit and at 6 weeks postpartum. An FFQ was administered at 6 weeks postpartum to explore the relationship between diet and postpartum weight retention.

Clinics at the University of the West Indies, Kingston, Jamaica.

Recruitment included women aged 19 years and younger (adolescent girls) and 20 years and older (older women).

Three hundred and forty women were studied. Adolescent girls had significantly lower measurements compared with the older women at the first antenatal visit and at 6 weeks postpartum. Dietary intakes of energy and macronutrients were similar in both groups. Postnatal assessments showed that adolescent girls retained more weight (P = 0·003) and a greater percentage of body fat (P < 0·002) than older women. In multiple regression analyses, 0·982 kg more fat mass was retained postpartum in the adolescent group compared with the older women, while there was no significant difference in lean body mass retained between the two groups.

Adolescent girls retained more weight postpartum and this was predominantly fat mass as opposed to lean body mass.

To assess the impact of an integrated community-based micronutrient and health (MICAH) programme on anaemia (Hb < 120 g/l) among non-pregnant rural Malawian women aged 15–49 years from communities that participated in the 1996–2005 MICAH programme.

Prospective study of two large-scale cross-sectional surveys conducted in 2000 and 2004 as part of programme evaluation in MICAH and Comparison areas.

Rural areas across Malawi. The MICAH programme implemented a comprehensive package of interventions to reduce anaemia, based on a broad range on direct and indirect causes in Malawi. The project approaches included: Fe supplementation; dietary diversification and modification; food fortification; and strengthening primary health care.

Non-pregnant women of childbearing age (15–49 years old, n 5422), from randomly selected households that responded to a household questionnaire, had their Hb measured from finger-prick blood samples using the HemoCue®.

In 2000, there was no significant difference in Hb concentration between MICAH and Comparison areas (mean (se): 117·4 (0·4) v. 116·8 (0·5) g/l, P > 0·05) and the corresponding prevalence of anaemia (53·5 % v. 52·9 %, P > 0·05). By 2004, Hb concentration had increased significantly in MICAH but not in Comparison areas (mean (se): 121·0 (0·4) v. 115·7 (0·6) g/l, P < 0·001), and the prevalence of anaemia had declined significantly in MICAH areas (53·5 % to 44·1 %, χ2 = 28·2, P < 0·0001) but not in Comparison areas (52·8 % to 54·0 %, χ2 = 0·3, P = 0·6).

The MICAH programme was an effective public health nutrition programme that was associated with significant reductions in the prevalence of anaemia among non-pregnant rural Malawian women.

To examine changes in breast-feeding and impacts on child health during the Bosnian conflict.

Four linked representative cross-sectional household surveys, 1994 to 1997.

The countries of former Yugoslavia largely missed the international wave of enthusiasm for breast-feeding of the 1980s and early 1990s. The concern is that breast-feeding deteriorates during humanitarian emergencies, when children need it most.

The four surveys visited a random sample of clusters from population registers in the Federation of Bosnia and Herzegovina (BiH) and the Republica Srpska (RS). Interviewers asked about breast-feeding and other factors related to child health, and measured mid upper-arm circumference in 1123 infants aged 1–12 months.

One-fifth of infants were not breast-fed at all (220/1087). Muslim and displaced children were less likely to breast-feed; 59 % of Muslim displaced children never breast-fed. Among infants in sites visited by all four surveys, there was no change in the proportion ever breast-fed and a significant increase in duration of breast-feeding and exclusive breast-feeding between 1994 and 1997. Children were breast-fed for shorter durations in male absent households, in frontline communities, the RS, and households that did not receive remittances from abroad. Non-breast-fed children and those who breast-fed for less than 4 months were more likely to be malnourished, as were those with complementary foods added either before or after their sixth month of life.

If relief agencies had promoted and supported breast-feeding, this might have avoided some of the increased malnutrition that occurred during the conflict.

To examine the association between energy density and energy costs in single food items and composed diets, and to explore differences in energy density and energy cost between income levels.

A cross-sectional study using data from two Dutch cohort studies and recent national food prices. Food prices were retrieved from two market leader supermarkets. Data on dietary intake were measured using a computerized face-to-face interview (cohort 1) and 24 h recalls (cohort 2).

The Netherlands.

A sample of 373 young adults from the Amsterdam Growth and Health Longitudinal Study (AGHLS, measured in 2000) and a sample of 200 community-dwelling elderly from the Longitudinal Ageing Study Amsterdam (LASA, measured in 2007).

We found significant inverse associations between energy density and energy costs in single food items (r = −0·436, P < 0·01) and composed diets (AGHLS men r = −0·505, women r = −0·413, P < 0·001; LASA men r = −0·559, women r = −0·562, P < 0·001). Furthermore, we found that people stratified into higher energy density quartiles consumed significantly more energy per day, less fruits and vegetables, and had significantly lower diet costs. Explorative analyses on income did not reveal significant differences regarding energy density, costs, or fruit and vegetable intake.

In the Netherlands also, energy density was inversely related with energy costs, implying that healthier diets cost more. However, we could not find differences in energy density or costs between income levels. Future research, using precise food expenditures, is of main importance in studying the economics of obesity and in the aim of making the healthier choice easier.

The present study was designed to determine household food security status and factors associated with food insecurity among high-school students in Esfahan, Iran.

Cross-sectional surveys.

The present study was conducted in autumn 2008 in Esfahan, Iran. The samples were selected using systematic cluster sampling. Socio-economic questionnaires, food security questionnaires and FFQ were filled out during face-to-face interviews. In addition, data on participants’ weights and heights were collected.

A total of 580 students (261 boys and 319 girls) aged 14–17 years from forty high schools in Esfahan, Iran, were selected.

The prevalence of household food insecurity according to the US Department of Agriculture food security questionnaire was 36·6 % (95 % CI 0·33, 0·40). Food insecurity was positively associated with number of members in the household (P < 0·05) and negatively associated with parental education level and job status and household economic status (P < 0·05). Moreover, students living in food-insecure households more frequently consumed bread, macaroni, potato and egg (P < 0·05), while they less frequently consumed rice, red meat, sausage and hamburger, poultry, fish, green vegetables, root and bulb (coloured) vegetables, melons, apples and oranges, milk and yoghurt (P < 0·05).

Food insecurity was prevalent among households in Esfahan, Iran, and food security status was associated with socio-economic factors. Students who belonged to food-secure households more frequently consumed healthy foods (except sausage and hamburger), whereas those living in food-insecure households more frequently consumed cheap foods containing high energy per kilogram. The present study suggests that intervention programmes be designed and carried out.

To investigate community engagement with the health benefits of dietary fibre (DF) and its potential as a framework for the promotion of increased consumption of resistant starch (RS).

A nationwide postal Food and Health Survey conducted in Australia by CSIRO Human Nutrition.

Adults aged 18 years and above, selected at random from the Australian Electoral Roll (n 849).

A cross-sectional design was employed to analyse ratings of (i) the importance of various RS health and functional claims and (ii) receptiveness to different foods as RS delivery vehicles, according to the respondents’ level of fibre engagement as classified under the Precaution Adoption Process Model (PAPM) of Health Behaviour.

There was a high level of recognition (89·5 %) of DF as being important for health. Significant gender differences were found for ratings of RS attributes and RS delivery options. Women were both more fibre-engaged than men and more receptive than men to RS and its potential benefits. Ratings of the acceptability of several foods as means of delivering RS revealed a general preference for healthy staples over indulgences, with the margin between acceptability of staples and indulgences increasing markedly with increased fibre engagement.

Application of the PAPM to awareness of DF reveals a ready-made target group for health messages about RS and pockets of differential potential receptiveness. The findings support the promotion of RS as providing health benefits of DF with the added reduction of risk of serious disease, its delivery through healthy staples and the targeting of messages at both fibre-engaged individuals and women in general.

The CSIRO Total Wellbeing Diet (TWD) publication is an evidence-based weight management strategy utilising a structured higher protein diet as part of a nutritionally balanced lifestyle programme. Despite its popularity, the impact of TWD on weight status, weight loss and food choices of Australians was unknown.

An independent representative survey was conducted in 2006. Sociodemographic differences in awareness, use of TWD and the impact on weight status and well-being were investigated via computer-aided telephone interviews and web-based surveys.

Australia.

A total of 5026 men and women aged 18–60 years.

Consumers were highly aware of TWD (66 %) with personal use reported by 7·5 % of the total sample (n 5026). An additional 2·5 % (126 people) were members of a household that used TWD. In all, 80 % of TWD purchasers actively used the eating plan with approximately 3·8 % losing an average self-reported weight loss of 5·7 kg (sd = 1·72 kg; range = 1–13 kg). Results showed that awareness was greatest among women (73·79 % v. 58·27 %), those over 50 years of age (69·39 % v. 62·88 %) with no children in the household (69·00 % v. 64·88 %), tertiary educated people (72·58 % v. 63·22 %) and those with more previous weight loss attempts (79·66 % v. 70·24 %). Logistic regression was unable to predict an identifiable sociodemographic profile of TWD users.

The present study shows widespread uptake of TWD in Australia with few sociodemographic differences. Self-reported increased awareness of nutrition and well-being as well as weight loss indicates that TWD has been a successful delivery mechanism for lifestyle advice.
