Which state government launched the “Poshan Abhiyan” nutrition campaign with the aim of eradicating or sharply reducing malnutrition among children and women?

Introduction / Context:
Malnutrition is a serious public health challenge in many parts of India, especially among children and women. To tackle this, both the central government and several state governments have launched targeted campaigns. One such effort is Poshan Abhiyan, a name that has been used for large scale nutrition initiatives. This question focuses on which state government launched a Poshan Abhiyan campaign aimed at eradicating or significantly reducing malnutrition.

Given Data / Assumptions:

• The question is about a state level nutrition campaign named Poshan Abhiyan.
• The main goal mentioned is to eradicate or control malnutrition, particularly among vulnerable groups.
• The options list Gujarat, Maharashtra, Mizoram and Tripura.
• We assume familiarity with recent health and nutrition related schemes in India.

Concept / Approach:
India has a national level Poshan Abhiyaan, but some states have also adopted the name and launched their own specific programmes. To answer this question, you need to remember which state government prominently launched a Poshan Abhiyan campaign with a focus on malnutrition. Gujarat is known for implementing a state level Poshan Abhiyan that works through local health workers, anganwadi centres and community outreach to combat undernutrition and anaemia.

Step-by-Step Solution:
Step 1: Recognise that the name Poshan Abhiyan has been used both at the national level and by some state governments for their own initiatives. Step 2: Recall that Gujarat launched a state level Poshan Abhiyan, integrating various nutrition and health programmes to reduce malnutrition among children and women. Step 3: Consider the other options. While Maharashtra, Mizoram and Tripura have their own health programmes, the name Poshan Abhiyan is particularly associated in exam material with Gujarat at the state level. Step 4: Check that Gujarat appears among the options provided. Step 5: Conclude that Gujarat is the correct answer for this question.

Verification / Alternative check:
To verify, you can look at official government documents and press releases from Gujarat, which describe the state level Poshan Abhiyan. These documents highlight objectives such as reducing stunting, wasting and underweight in children, improving maternal health and strengthening service delivery through anganwadis and health centres. Media coverage and exam oriented capsules on state schemes also mention Gujarat in this context.

Why Other Options Are Wrong:
Maharashtra, Mizoram and Tripura may have launched nutrition or health campaigns, but they are not as commonly linked in exam based general knowledge with a specific state level Poshan Abhiyan by this exact name. Since the question expects you to identify the state usually associated with Poshan Abhiyan in a competitive exam context, choosing any of these states would not match the intended answer.

Thus, although other states work on malnutrition issues, the question here points to Gujarat.

Common Pitfalls:
A common mistake is to confuse the central Poshan Abhiyaan with state campaigns and assume that any state could be the answer. Another pitfall is not tracking state specific schemes separately from national schemes. To avoid confusion, maintain separate notes for central government programmes and for major state initiatives, especially when they share similar names.

Final Answer:
The Poshan Abhiyan nutrition campaign referred to in this question was launched by the government of Gujarat.
